'''John''' ''(Johannes, Ioannes)'' '''Duns Scotus''', [[Order of Friars Minor|O.F.M.]] (c. 1265&nbsp;– November 8, 1308) is generally reckoned to be one of the three most important philosopher-theologians of the [[High Middle Ages]].<ref>Together with [[Thomas Aquinas]] and [[William of Ockham]]. See e.g. the articles [http://plato.stanford.edu/entries/duns-scotus/ Duns Scotus] and [http://plato.stanford.edu/entries/ockham/ William of Ockham]</ref> Scotus has had considerable influence on both [[Roman Catholic|Catholic]] and secular thought. The doctrines for which he is best known are the "[[univocity]] of being," that existence is the most abstract concept we have, applicable to everything that exists; the [[formal distinction]], a way of distinguishing between different aspects of the same thing; and the idea of [[haecceity]], the property supposed to be in each individual thing that makes it an individual. Scotus also developed a complex argument for the [[existence of God]], and argued for the [[Immaculate conception]] of [[Mary (mother of Jesus)|Mary]].

Little is known of Scotus' life. He was probably born in 1265 or 1276,<ref>Brampton 'Duns Scotus at Oxford, 1288-1301', Franciscan Studies, 24 (1964) 17.</ref> probably at [[Duns]], in [[Berwickshire]], [[Scotland]]. In 1291 he was ordained as a priest in [[Northampton, England|Northampton]], [[England]]. A note in Codex 66 of [[Merton College, Oxford]], records that Scotus "flourished at [[Cambridge, England|Cambridge]], [[Oxford, England|Oxford]] and [[Paris]].<ref>Frank & Wollter p.5</ref> He began lecturing on [[Peter Lombard|Peter Lombard's]] [[Sentences]] at the prestigious [[University of Paris]] in the Autumn of 1302. Later in that academic year, however, he was expelled from the University of Paris for siding with then [[Pope Boniface VIII]] in his feud with [[Philip IV of France|Philip the Fair]] of France, over the taxation of church property.
Little is known of Scotus apart from his work. His date of birth is generally given as 1265, based on his ordination to the priesthood in the Order of Friars Minor (the [[Franciscan]]s) at Saint Andrew's Priory in Northampton, England, on 17 March 1291. On the assumption that the minimum age for ordination was 25, and that he would have been ordained as soon as this was permitted, this places his birth some time before 17 March 1266.<ref>Brampton 'Duns Scotus at Oxford, 1288–1301', Franciscan Studies, 24 (1964) 17</ref> That his contemporaries called him ''Johannes Duns'', after the medieval practice of calling people by their Christian name followed by their place of origin, suggests that he came from [[Duns]], in [[Berwickshire]], now in [[Scotland]].<ref>Although Vos (2006, p. 23) has objected that ‘Duns’ was actutally his family name, as someone from Duns would have been known as ‘de Duns’</ref>


According to tradition, he was educated at the Franciscan ''[[studium]]'' at Oxford, a house behind [[St Ebbe's Church, Oxford|St Ebbe's Church]], in a triangular area enclosed by Pennyfarthing Street and running from [[St Aldate's, Oxford|St Aldate's]] to the Castle, the Baley and the old wall,<ref>Vos 2006 p. 27. See also Roest 2000, 21–24.</ref> where the Franciscans had moved when the [[University of Paris]] was dispersed in 1229–30. At that time there would have been about 270 persons living there, of whom about 80 would have been Franciscans.<ref>Vos ibid.</ref>
Scotus was back in Paris before the end of 1304, probably returning in May. He continued lecturing there until, for reasons which are still mysterious, he was dispatched to the Franciscan ''studium'' at [[Cologne]], probably in October 1307. He died there in 1308; the date of his death is traditionally given as 8 November.


He appears to have been in Oxford in 1300–01, taking part in a disputation under the regent master, Philip of Bridlington. He began lecturing on [[Peter Lombard|Peter Lombard's]] ''[[Sentences]]'' at the prestigious University of Paris in the Autumn of 1302. Later in that academic year, however, he was expelled from the University of Paris for siding with [[Pope Boniface VIII]] in his feud with [[Philip IV of France|Philip the Fair]] of France, over the taxation of church property.
He is buried in the Church of the [[Franciscans]] in Cologne. His sarcophagus bears the Latin inscription: ''Scotia me genuit. Anglia me suscepit. Gallia me docuit. Colonia me tenet.'' (trans. "Scotland brought me forth. England sustained me. France taught me. Cologne holds me.") He was [[beatification|beatified]] by [[Pope John Paul II]] on March 20, 1993. According to an old tradition, Scotus was buried alive following his lapse into a coma.

Scotus was back in Paris before the end of 1304, probably returning in May. He continued lecturing there until, for reasons which are still mysterious, he was dispatched to the Franciscan ''studium'' at [[Cologne]], probably in October 1307. According to the fifteenth century writer [[William Vorilong]], his departure was sudden and unexpected. He was relaxing or talking with students in the ''Prato clericorum'' or ''Pre-aux-Clercs'' – an open area of the [[Left Bank]] used by scholars for recreation, when orders arrived from the Franciscan Minister General. Scotus left immediately, taking few or no personal belongings.<ref>''Narratur de Doctori Subtili qui in Prato clericorum, visa Generalis Ministri obedentia, dum actu Regens esse in scholis Parisiensibus, aut pauca aut nulla de rebus habita dispositione, Parisis exivit ut Coloniam iret, secundum ministri sententiam''. William Vorilong, Opus super IV libros Sententiarum II, d. 44, q. 1 f. 161va</ref>

He died there in 1308; the date of his death is traditionally given as 8 November. He is buried in the Church of the [[Franciscans]] in Cologne. His sarcophagus bears the Latin inscription: ''Scotia me genuit. Anglia me suscepit. Gallia me docuit. Colonia me tenet.'' (trans. "Scotland brought me forth. England sustained me. France taught me. Cologne holds me.") He was [[beatification|beatified]] by [[Pope John Paul II]] on March 20, 1993. The story about Scotus being buried alive, in the absence of his servant who alone knew of his susceptibility to coma, is probably a myth. It was reported by [[Sir Francis Bacon]] in his ''Historia vitae et mortis''.<ref>1638</ref>

The colophon of Codex 66 of [[Merton College, Oxford]] says that Scotus was also at [[Cambridge, England|Cambridge]], but we do not know for certain if this is true, or if it was, when he was there.<ref>(''Haec de ordinatione ven. Fratris J. duns de ordine fratrum Minorum, qui floruit Cant Oxon et Parisius et obiit in Colonia.'' – quoted in Little 1932, p. 571, citing Callebaut 1928</ref>

== Work ==

Scotus’ great work is his commentary on the [[sentences]] of Peter Lombard, which contains nearly all the philosophical views and arguments for which he is well known, including the univocity of being, the [[formal distinction]], less-than-numerical unity, individual nature or ‘thisness' ([[haecceity]]), his critique of [[illuminationism]] and his renowned argument for the [[existence of God]]. It exists in several versions. The standard version is the ''Ordinatio'' (also known as the ''Opus oxoniense''). It is a revised version of lectures he gave as a bachelor at Oxford. The initial revision was probably begun in the summer of 1300 – see the remarks in the Prologue, question 2, alluding to the [[Third Battle of Homs]] in 1299, news of which probably reached Oxford in the summer of 1300. It was still incomplete when Scotus left for Paris in 1302. The original lectures were also transcribed and recently published as the ''Lectura''.

The two other versions of the work are Scotus' notes for the Oxford lectures, recently published as the ''Lectura'', the first book of which was probably written in Oxford in the late 1290s<ref>"Univocity in Scotus’s Quaestiones super Metaphysicam: The Solution to a Riddle" (Medioevo 30 2005, 69–110)</ref>", and the ''Reportatio parisiensis'' (or ''Opus parisiense''), consisting of transcriptions of the lectures on the Sentences given by Scotus when he was in Paris. A reportatio is a student report or transcription of the original lecture of a master. A version that has been checked by the master himself is known as a ''reportatio examinata''.

By the time of Scotus, these 'commentaries' on the Sentences were no longer literal commentaries. Instead, Peter Lombard's original text was used as a starting point for highly original discussions on topics of theological or philosophical interest.<ref>See e.g. Wollter 1995, p.76 and ''passim''</ref> For example, Book II distinction 2, about the location of angels, is a starting point for a complex discussion about continuous motion, and whether the same thing can be in two different places at the same time. In the same book, distinction 3, he uses the question of how angels can be different from one another, given that they have no material bodies, to investigate the difficult question of individuation in general.

Scotus wrote purely philosophical and logical works at an early stage of his career, consisting of commentaries on Aristotle's [[Organon]]. These are the ''questions'' on Porphyry's ''[[Isagoge]]'' and Aristotle's ''[[Categories (Aristotle)|Categories]]'', ''[[De Interpretatione|Peri hermeneias]]'', and ''[[Sophistical Refutations|De sophisticis elenchis]]'', probably dating to around 1295.<ref>see the introduction to the critical edition: ''Duns Scoti Quaestiones in librum Porphyrii Isagoge et Quaestiones super Praedicamenta Aristotelis'' (''Opera philosophica'', I), xxix–xxxiv, xli–xlii.</ref> His commentary on [[Metaphysics (Aristotle)|Aristotle's Metaphysics]] was probably written in stages, the first version having started around 1297,<ref>according to Pini, 2005</ref> with significant additions and amendments possibly after the completion of the main body of the ''Ordinatio''.<ref>Pini, 2005, although this is speculative</ref> His ''Expositio'' on the Metaphysics was lost for centuries but was recently rediscovered and edited by Giorgio Pini.

In addition, there are 46 short disputations called ''Collationes'' probably dating from 1300–1305; a work in natural theology (''De primo principio''), and his ''Quaestiones Quodlibetales'' probably dating to Advent 1306 or Lent 1307.

A number of works once attributed to Scotus are now known to be inauthentic. There were already concerns about this within two centuries of his death, when the sixteenth-century logician [[Jacobus Naveros]] noted inconsistencies between these texts and his commentary on the ''Sentences'', leading him to doubt whether he had written any logical works at all.<ref>Ashworth 1987</ref> The Questions on the Prior Analytics (''In Librum Priorum Analyticorum Aristotelis Quaestiones'') were also discovered to be mistakenly attributed.<ref>R.P.E. Longpre</ref> In 1922, [[Martin Grabmann| Grabmann]] showed that the logical work ''De modis significandi'' was actually to be by [[Thomas of Erfurt]], a fourteenth-century logician of the [[modist]] school. Thus the claim that [[Martin Heidegger]] wrote his ''Habilitationsschrift'' on Scotus is only half true, as the second part is actually based on the work by Erfurt.

It reads ''Explicit Scriptum super Primum Sententiarum: editum a fratre Johanne Duns: ordinis fratrum minorum'' Printed versions of scholastic manuscripts became popular in the late fifteenth century.]]Owing to Scotus' early and unexpected death, he left behind a large body of work in an unfinished or unedited condition. His students and disciples extensively edited his papers, often confusing them with works by other writers, in many cases leading to misattribution and confused transmission. Most thirteenth-century Franciscans followed [[Bonaventure|Bonaventura]], but the influence of Scotus (as well as that of his arch-rival [[William of Ockham]]) spread in the fourteenth century. Franciscan theologians in the late Middle Ages were thus divided between so-called Scotists and Ockhamists.<ref>Janz</ref> Fourteenth century followers included [[Francis of Mayrone]] (d. 1325), [[Antonius Andreas]] (d. 1320), [[William of Alnwick]] (d. 1333), and John of Bassolis (d. 1347), supposedly Scotus' favourite student.<ref>Courtenay, W., "Early Scotists at Paris: A Reconsideration", ''Franciscan Studies'' 69, 2011, pp. 175–229</ref>

Scotus is considered one of the most important [[Franciscan]] theologians and was the founder of [[Scotism]], a special form of [[Scholasticism]]. He came out of the Old Franciscan School, to which [[Haymo of Faversham]] (d. 1244), [[Alexander of Hales]] (d. 1245), [[John of Rupella]] (d. 1245), [[William of Melitona]] (d. 1260), St. [[Bonaventure]] (d. 1274), [[Cardinal (Catholicism)|Cardinal]] [[Matthew of Aquasparta]] (d. 1289), [[John Peckham]], Archbishop of Canterbury (d. 1292), [[Richard of Middletown]] (d. about 1300), etc., belonged. He was known as "Doctor Subtilis" because of the subtle distinctions and nuances of his thinking. Later philosophers in the sixteenth century were less complimentary about his work, and accused him of [[Sophism|sophistry]]. This led to his name, "[[dunce]]" (which developed from the name "Dunse" given to his followers in the 1500s) to become synonymous for "somebody who is incapable of [[Scholarly method|scholarship]]". Duns Scotus is usually considered the beginning of the formal Scottish tradition of philosophy which moved through Duns Scotus, [[Adam Smith]], [[David Hume]], [[Thomas Reid]] and [[John Stuart Mill]].
His reputation suffered during the [[English reformation]], probably due to its association with the Franciscans. In a letter to [[Thomas Cromwell]] about his visit to Oxford in 1535, [[Richard Layton]] described how he saw the court of New College full of pages from Scotus's work "the wind blowing them into every corner".<ref>R.W. Dixon, ''History of the Church of England from the Abolition of the Roman Jurisdiction'', 1:303</ref> [[John Leland (antiquary)|John Leland]] described the Oxford Greyfriar's library in 1538 (just prior to its dissolution) as an accumulation of 'cobwebs, moths and bookworms'.<ref>Catto, J., "Franciscan Learning in England, 1450–1540", in ''The Religious Orders in Pre-Reformation England'', ed. Clarke 2002</ref> There is a story that the name "dunce" (which developed from the name "Dunse" given to his followers in the 1500s) became synonymous for "somebody who is incapable of scholarship".

Despite this, Scotism grew in Catholic Europe. Scotus' works were collected into many editions, particularly in the late fifteenth century with the advent of [[printing]]. His school was probably at the height of its popularity at the beginning of the seventeenth century; during the sixteenth and the seventeenth centuries there were even special Scotist chairs, e.g. at Paris, Rome, Coimbra, Salamanca, Alcalá, Padua, and Pavia. It flourished well into the seventeenth century, and its influence can be seen in such writers as [[Descartes]] and Bramhall. Interest dwindled in the eighteenth century, and the revival of scholastic philosophy, known as [[Neo-Scholasticism]], was essentially a revival of Thomistic thinking. The twentieth century, however, has seen a resurgence of interest in Scotus, particularly among secular philosophers such as Peter King, Gyula Klima, Paul Vincent Spade and others.

=== Realism ===
=== Realism ===
Scotus is generally considered to be a [[Philosophical realism|realist]] (as opposed to a [[nominalist]]) in that he treated universals as real. He attacks a position close to that later defended by [[William of Ockham|Ockham]], arguing that things have a common nature – for example the humanity common to both Socrates and Plato.

=== Univocity of Being ===
=== Univocity of Being ===
He followed [[Aristotle]] in asserting that the subject matter of [[metaphysics]] is "being qua being" (''ens inquantum ens''). Being in general (''ens in communi''), as a univocal notion, was for him the first object of the intellect. Metaphysics includes the study of the transcendentals, so called because they transcend the division of being into finite and infinite and the further division of finite being into the ten [[Categories (Aristotle)|Aristotelian categories]]. Being itself is a transcendental, and so are the "attributes" of being — "one," "true," and "good" — which are coextensive with being, but which each add something to it.

The doctrine of the univocity of being implies the denial of any real distinction between [[essence]] and [[existence]]. [[Aquinas]] had argued that in all finite being (i.e. all except God), the essence of a thing is distinct from its existence. Scotus rejected the distinction. Scotus argued that we can not conceive of what it is to be something, without conceiving it as existing. We should not make any distinction between whether a thing exists (''si est'') and what it is (''quid est''), for we never know whether something exists, unless we have some concept of what we know to exist.<ref>''Opus Oxoniense'' I iii 1-2, quoted in Grenz p.55</ref>

=== Categories ===
The study of the Aristotelian categories belongs to metaphysics insofar as the categories, or the things falling under them, are studied as beings. (If they are studied as concepts, they belong instead to the logician.) There are exactly ten categories, according to orthodox Aristotelianism. The first and most important is the category of [[Substance theory|substance]]. Substances are beings in a primary sense, since they have an independent existence (''entia per se''). Beings in any of the other nine categories, called [[Accident (philosophy)|accidents]], exist in substances. The nine categories of accidents are quantity, quality, relation, action, passion, place, time, position, and state (or ''habitus'').


=== Individuation ===
=== Individuation ===
Duns elaborates a distinct view on [[hylomorphism]], with three important strong theses that differentiate him. He held: 1) that there exists [[matter]] that has no form whatsoever, or prime matter, as the stuff underlying all change, against Aquinas (cf. his ''Quaestiones in Metaphysicam'' 7, q. 5; ''Lectura'' 2, d. 12, q. un.), 2) that not all created substances are composites of form and matter (cf. ''Lectura'' 2, d. 12, q. un., n. 55), that is, that purely spiritual substances do exist, and 3) that one and the same substance can have more than one substantial form — for instance, humans have at least two substantial forms, the soul and the form of the body (''forma corporeitas'') (cf. ''Ordinatio'' 4, d. 11, q. 3, n. 54). He argued for an original principle of [[individuation]] (cf. ''Ordinatio'' 2, d. 3, pars 1, qq. 1-6), the "[[haecceity]]" as the ultimate unity of a unique individual (''haecceitas'', an entity's 'thisness'), as opposed to the common [[Nature (philosophy)|nature]] (''natura communis''), feature existing in any number of individuals. For Scotus, the axiom stating that only the individual exists is a dominating principle of the understanding of reality. For the apprehension of individuals, an intuitive cognition is required, which gives us the present existence or the non-existence of an individual, as opposed to abstract cognition. Thus the human soul, in its separated state from the body, will be capable of knowing the spiritual intuitively.

=== Formal distinction ===
=== Formal distinction ===
Like other realist philosophers of the period (such as Aquinas and [[Henry of Ghent]]) Scotus recognised the need for an intermediate distinction that was not merely conceptual, but not fully real or mind-dependent either. Scotus argued for an [[formal distinction]] (''distinctio formalis a parte rei''), which holds between entities which are inseparable and indistinct in reality, but whose definitions are not identical. For example, the personal properties of the [[Trinity]] are formally distinct from the Divine essence. Similarly, the distinction between the 'thisness' or ''haecceity'' of a thing is intermediate between a real and a conceptual distinction.<ref>Honderich p. 209</ref> There is also a formal distinction between the divine attributes and the powers of the soul.

The existence of God can be proven only ''a posteriori'', through its effects. The Causal Argument he gives for the existence of [[God]] says that an infinity of things that are essentially ordered is impossible, as the totality of caused things that are essentially caused is itself caused, and so it is caused by some cause which is not a part of the totality, for then it would be the cause of itself; for the whole totality of dependent things is cause, and not on anything belonging to that totality. The argument is relevant for Scotus' conception of metaphysical inquiry into being by searching the ways into which beings relate to each other.

Scotus argued against the version of [[illuminationism]] that had been defended earlier in the century by [[Henry of Ghent]]. In his ''Ordinatio'' (I.3.1.4) he argued against the sceptical consequences that Henry claimed would follow from abandoning divine illumination. Scotus argued that if our thinking were fallible in the way Henry had believed, such illumination could not, even in principle, ensure "certain and pure knowledge."<ref>[http://plato.stanford.edu/entries/illumination/ Stanford Encyclopedia of Philosophy]</ref>

=== Immaculate Conception ===
=== Immaculate Conception ===
Perhaps the most influential point of Duns Scotus' theology was his defense of the [[Immaculate Conception]] of [[Blessed Virgin Mary|Mary]]. At the time, there was a great deal of argument about the subject. The general opinion was that it was appropriately deferential to the [[Mother of God]], but it could not be seen how to resolve the problem that only with [[Jesus|Christ]]'s death would the stain of [[original sin]] be removed. The great philosophers and theologians of the West were divided on the subject (indeed, it appears that even [[Thomas Aquinas]] sided with those who denied the doctrine, though some [[Thomism|Thomists]] dispute this). The [[feast of the Immaculate Conception|feast day]] had existed in the East (though in the East, the feast is just of the Conception of Mary as the Immaculate Conception of Mary is seen as a heresy in the East) since the seventh century and had been introduced in several dioceses in the West as well, even though the philosophical basis was lacking. Citing [[Anselm of Canterbury]]'s principle, "''potuit, decuit, ergo fecit''" ([[God]] could do it, it was appropriate, therefore he did it), Duns Scotus devised the following argument: Mary was in need of redemption like all other human beings, but through the merits of Jesus' [[crucifixion]], given in advance, she was conceived without the stain of original sin. God could have brought it about (1) that she was never in original sin, (2) she was in sin only for an instant, (3) she was in sin for a period of time, being purged at the last instant. Whichever of these options was most excellent should probably be attributed to Mary.<ref>''Ordinatio'' III, d.3, q.1</ref> This apparently careful statement provoked a storm of opposition at Paris, and suggested the line 'fired France for Mary without spot' in the famous poem "Duns Scotus's Oxford," by [[Gerard Manley Hopkins]].

This argument appears in [[Pope Pius IX]]'s declaration of the [[dogma]] of the Immaculate Conception. [[Pope John XXIII]] recommended the reading of Duns Scotus' theology to modern theology students.

The authenticity of Scotus' [[Logic|logical works]] has been questioned. Some of the logical and metaphysical works originally attributed to him are now known to be by other authors. There were already concerns about this within two centuries of his death, when the sixteenth-century logician [[Jacobus Naveros]] noted inconsistencies between these texts and his commentary on the ''Sentences'', leading him to doubt whether he had written any logical works at all.<ref>Ashworth 1987</ref> The Questions on the Prior Analytics (''In Librum Priorum Analyticorum Aristotelis Quaestiones'') were also discovered to be mistakenly attributed.<ref>R.P.E.

* [[Dunce]]
Modern editors have identified only four works as authentic: the commentaries on Porphyry's [[Isagoge]], on Aristotle's Categories, [[On Interpretation]] (in two different versions), and on [[Sophistical Refutations]], probably written in that order. These are called the ''parva logicalia''. These are dated at around 1295, when Scotus would have been in his late twenties, working in Cambridge.

John (Johannes, Ioannes) Duns Scotus, O.F.M. (c. 1265 – November 8, 1308) is generally reckoned to be one of the three most important philosopher-theologians of the High Middle Ages.[1] Scotus has had considerable influence on both Catholic and secular thought. The doctrines for which he is best known are the "univocity of being," that existence is the most abstract concept we have, applicable to everything that exists; the formal distinction, a way of distinguishing between different aspects of the same thing; and the idea of haecceity, the property supposed to be in each individual thing that makes it an individual. Scotus also developed a complex argument for the existence of God, and argued for the Immaculate conception of Mary.

He was given the medieval accolade Doctor Subtilis (Subtle Doctor) for his penetrating and subtle manner of thought.

Life

Plaque commemorating Duns Scotus in the University Church, Oxford.

Little is known of Scotus apart from his work. His date of birth is generally given as 1265, based on his ordination to the priesthood in the Order of Friars Minor (the Franciscans) at Saint Andrew's Priory in Northampton, England, on 17 March 1291. On the assumption that the minimum age for ordination was 25, and that he would have been ordained as soon as this was permitted, this places his birth some time before 17 March 1266.[2] That his contemporaries called him Johannes Duns, after the medieval practice of calling people by their Christian name followed by their place of origin, suggests that he came from Duns, in Berwickshire, now in Scotland.[3]

According to tradition, he was educated at the Franciscan studium at Oxford, a house behind St Ebbe's Church, in a triangular area enclosed by Pennyfarthing Street and running from St Aldate's to the Castle, the Baley and the old wall,[4] where the Franciscans had moved when the University of Paris was dispersed in 1229–30. At that time there would have been about 270 persons living there, of whom about 80 would have been Franciscans.[5]

He appears to have been in Oxford in 1300–01, taking part in a disputation under the regent master, Philip of Bridlington. He began lecturing on Peter Lombard's Sentences at the prestigious University of Paris in the Autumn of 1302. Later in that academic year, however, he was expelled from the University of Paris for siding with Pope Boniface VIII in his feud with Philip the Fair of France, over the taxation of church property.

Scotus was back in Paris before the end of 1304, probably returning in May. He continued lecturing there until, for reasons which are still mysterious, he was dispatched to the Franciscan studium at Cologne, probably in October 1307. According to the fifteenth century writer William Vorilong, his departure was sudden and unexpected. He was relaxing or talking with students in the Prato clericorum or Pre-aux-Clercs – an open area of the Left Bank used by scholars for recreation, when orders arrived from the Franciscan Minister General. Scotus left immediately, taking few or no personal belongings.[6]

He died there in 1308; the date of his death is traditionally given as 8 November. He is buried in the Church of the Franciscans in Cologne. His sarcophagus bears the Latin inscription: Scotia me genuit. Anglia me suscepit. Gallia me docuit. Colonia me tenet. (trans. "Scotland brought me forth. England sustained me. France taught me. Cologne holds me.") He was beatified by Pope John Paul II on March 20, 1993. The story about Scotus being buried alive, in the absence of his servant who alone knew of his susceptibility to coma, is probably a myth. It was reported by Sir Francis Bacon in his Historia vitae et mortis.[7]

The colophon of Codex 66 of Merton College, Oxford says that Scotus was also at Cambridge, but we do not know for certain if this is true, or if it was, when he was there.[8]

Work

Scotus’ great work is his commentary on the sentences of Peter Lombard, which contains nearly all the philosophical views and arguments for which he is well known, including the univocity of being, the formal distinction, less-than-numerical unity, individual nature or ‘thisness' (haecceity), his critique of illuminationism and his renowned argument for the existence of God. It exists in several versions. The standard version is the Ordinatio (also known as the Opus oxoniense). It is a revised version of lectures he gave as a bachelor at Oxford. The initial revision was probably begun in the summer of 1300 – see the remarks in the Prologue, question 2, alluding to the Third Battle of Homs in 1299, news of which probably reached Oxford in the summer of 1300. It was still incomplete when Scotus left for Paris in 1302. The original lectures were also transcribed and recently published as the Lectura.

The two other versions of the work are Scotus' notes for the Oxford lectures, recently published as the Lectura, the first book of which was probably written in Oxford in the late 1290s[9]", and the Reportatio parisiensis (or Opus parisiense), consisting of transcriptions of the lectures on the Sentences given by Scotus when he was in Paris. A reportatio is a student report or transcription of the original lecture of a master. A version that has been checked by the master himself is known as a reportatio examinata.

By the time of Scotus, these 'commentaries' on the Sentences were no longer literal commentaries. Instead, Peter Lombard's original text was used as a starting point for highly original discussions on topics of theological or philosophical interest.[10] For example, Book II distinction 2, about the location of angels, is a starting point for a complex discussion about continuous motion, and whether the same thing can be in two different places at the same time. In the same book, distinction 3, he uses the question of how angels can be different from one another, given that they have no material bodies, to investigate the difficult question of individuation in general.

Scotus wrote purely philosophical and logical works at an early stage of his career, consisting of commentaries on Aristotle's Organon. These are the questions on Porphyry's Isagoge and Aristotle's Categories, Peri hermeneias, and De sophisticis elenchis, probably dating to around 1295.[11] His commentary on Aristotle's Metaphysics was probably written in stages, the first version having started around 1297,[12] with significant additions and amendments possibly after the completion of the main body of the Ordinatio.[13] His Expositio on the Metaphysics was lost for centuries but was recently rediscovered and edited by Giorgio Pini.

In addition, there are 46 short disputations called Collationes probably dating from 1300–1305; a work in natural theology (De primo principio), and his Quaestiones Quodlibetales probably dating to Advent 1306 or Lent 1307.

A number of works once attributed to Scotus are now known to be inauthentic. There were already concerns about this within two centuries of his death, when the sixteenth-century logician Jacobus Naveros noted inconsistencies between these texts and his commentary on the Sentences, leading him to doubt whether he had written any logical works at all.[14] The Questions on the Prior Analytics (In Librum Priorum Analyticorum Aristotelis Quaestiones) were also discovered to be mistakenly attributed.[15] In 1922, Grabmann showed that the logical work De modis significandi was actually to be by Thomas of Erfurt, a fourteenth-century logician of the modist school. Thus the claim that Martin Heidegger wrote his Habilitationsschrift on Scotus is only half true, as the second part is actually based on the work by Erfurt.

Reputation and influence

Colophon from the edition of Scotus' Sentences commentary edited by Thomas Penketh (d. 1487) and Bartolomeo Bellati (d.1479), printed by Johannes de Colonia and Johannes Manthen,Venice in 1477. It reads Explicit Scriptum super Primum Sententiarum: editum a fratre Johanne Duns: ordinis fratrum minorum Printed versions of scholastic manuscripts became popular in the late fifteenth century.

Owing to Scotus' early and unexpected death, he left behind a large body of work in an unfinished or unedited condition. His students and disciples extensively edited his papers, often confusing them with works by other writers, in many cases leading to misattribution and confused transmission. Most thirteenth-century Franciscans followed Bonaventura, but the influence of Scotus (as well as that of his arch-rival William of Ockham) spread in the fourteenth century. Franciscan theologians in the late Middle Ages were thus divided between so-called Scotists and Ockhamists.[16] Fourteenth century followers included Francis of Mayrone (d. 1325), Antonius Andreas (d. 1320), William of Alnwick (d. 1333), and John of Bassolis (d. 1347), supposedly Scotus' favourite student.[17]

His reputation suffered during the English reformation, probably due to its association with the Franciscans. In a letter to Thomas Cromwell about his visit to Oxford in 1535, Richard Layton described how he saw the court of New College full of pages from Scotus's work "the wind blowing them into every corner".[18] John Leland described the Oxford Greyfriar's library in 1538 (just prior to its dissolution) as an accumulation of 'cobwebs, moths and bookworms'.[19] There is a story that the name "dunce" (which developed from the name "Dunse" given to his followers in the 1500s) became synonymous for "somebody who is incapable of scholarship".

Despite this, Scotism grew in Catholic Europe. Scotus' works were collected into many editions, particularly in the late fifteenth century with the advent of printing. His school was probably at the height of its popularity at the beginning of the seventeenth century; during the sixteenth and the seventeenth centuries there were even special Scotist chairs, e.g. at Paris, Rome, Coimbra, Salamanca, Alcalá, Padua, and Pavia. It flourished well into the seventeenth century, and its influence can be seen in such writers as Descartes and Bramhall. Interest dwindled in the eighteenth century, and the revival of scholastic philosophy, known as Neo-Scholasticism, was essentially a revival of Thomistic thinking. The twentieth century, however, has seen a resurgence of interest in Scotus, particularly among secular philosophers such as Peter King, Gyula Klima, Paul Vincent Spade and others.

Metaphysics

Template:Expert-subject-multiple

Realism

Scotus is generally considered to be a realist (as opposed to a nominalist) in that he treated universals as real. He attacks a position close to that later defended by Ockham, arguing that things have a common nature – for example the humanity common to both Socrates and Plato.

Univocity of Being

He followed Aristotle in asserting that the subject matter of metaphysics is "being qua being" (ens inquantum ens). Being in general (ens in communi), as a univocal notion, was for him the first object of the intellect. Metaphysics includes the study of the transcendentals, so called because they transcend the division of being into finite and infinite and the further division of finite being into the ten Aristotelian categories. Being itself is a transcendental, and so are the "attributes" of being — "one," "true," and "good" — which are coextensive with being, but which each add something to it.

The doctrine of the univocity of being implies the denial of any real distinction between essence and existence. Aquinas had argued that in all finite being (i.e. all except God), the essence of a thing is distinct from its existence. Scotus rejected the distinction. Scotus argued that we can not conceive of what it is to be something, without conceiving it as existing. We should not make any distinction between whether a thing exists (si est) and what it is (quid est), for we never know whether something exists, unless we have some concept of what we know to exist.[20]

Individuation

Duns elaborates a distinct view on hylomorphism, with three important strong theses that differentiate him. He held: 1) that there exists matter that has no form whatsoever, or prime matter, as the stuff underlying all change, against Aquinas (cf. his Quaestiones in Metaphysicam 7, q. 5; Lectura 2, d. 12, q. un.), 2) that not all created substances are composites of form and matter (cf. Lectura 2, d. 12, q. un., n. 55), that is, that purely spiritual substances do exist, and 3) that one and the same substance can have more than one substantial form — for instance, humans have at least two substantial forms, the soul and the form of the body (forma corporeitas) (cf. Ordinatio 4, d. 11, q. 3, n. 54). He argued for an original principle of individuation (cf. Ordinatio 2, d. 3, pars 1, qq. 1–6), the "haecceity" as the ultimate unity of a unique individual (haecceitas, an entity's 'thisness'), as opposed to the common nature (natura communis), feature existing in any number of individuals. For Scotus, the axiom stating that only the individual exists is a dominating principle of the understanding of reality. For the apprehension of individuals, an intuitive cognition is required, which gives us the present existence or the non-existence of an individual, as opposed to abstract cognition. Thus the human soul, in its separated state from the body, will be capable of knowing the spiritual intuitively.

Formal distinction

Like other realist philosophers of the period (such as Aquinas and Henry of Ghent) Scotus recognised the need for an intermediate distinction that was not merely conceptual, but not fully real or mind-dependent either. Scotus argued for an formal distinction (distinctio formalis a parte rei), which holds between entities which are inseparable and indistinct in reality, but whose definitions are not identical. For example, the personal properties of the Trinity are formally distinct from the Divine essence. Similarly, the distinction between the 'thisness' or haecceity of a thing is intermediate between a real and a conceptual distinction.[21] There is also a formal distinction between the divine attributes and the powers of the soul.

Theology

Template:Expert-subject-multiple

Voluntarism

Scotus was an Augustinian theologian. He is usually associated with voluntarism, the tendency to emphasize God's will and human freedom in all philosophical issues. The main difference between Aquinas' rational theology and that of Scotus' is that Scotus believed certain predicates may be applied univocally — with exactly the same meaning — to God and creatures, whereas Aquinas insisted that this is impossible, and that only analogical predication can be employed, in which a word as applied to God has a meaning different from, although related to, the meaning of that same word as applied to creatures. Duns struggled throughout his works in demonstrating his univocity theory against Aquinas' analogy doctrine.

Existence of God

The existence of God can be proven only a posteriori, through its effects. The Causal Argument he gives for the existence of God says that an infinity of things that are essentially ordered is impossible, as the totality of caused things that are essentially caused is itself caused, and so it is caused by some cause which is not a part of the totality, for then it would be the cause of itself; for the whole totality of dependent things is cause, and not on anything belonging to that totality. The argument is relevant for Scotus' conception of metaphysical inquiry into being by searching the ways into which beings relate to each other.

Illuminationism

Scotus argued against the version of illuminationism that had been defended earlier in the century by Henry of Ghent. In his Ordinatio (I.3.1.4) he argued against the sceptical consequences that Henry claimed would follow from abandoning divine illumination. Scotus argued that if our thinking were fallible in the way Henry had believed, such illumination could not, even in principle, ensure "certain and pure knowledge."[22]

When one of those that come together is incompatible with certainty, then certainty cannot be achieved. For just as from one premise that is necessary and one that is contingent nothing follows but a contingent conclusion, so from something certain and something uncertain, coming together in some cognition, no cognition that is certain follows (Ordinatio I.3.1.4 n.221).

Immaculate Conception

Perhaps the most influential point of Duns Scotus' theology was his defense of the Immaculate Conception of Mary. At the time, there was a great deal of argument about the subject. The general opinion was that it was appropriately deferential to the Mother of God, but it could not be seen how to resolve the problem that only with Christ's death would the stain of original sin be removed. The great philosophers and theologians of the West were divided on the subject (indeed, it appears that even Thomas Aquinas sided with those who denied the doctrine, though some Thomists dispute this). The feast day had existed in the East (though in the East, the feast is just of the Conception of Mary as the Immaculate Conception of Mary is seen as a heresy in the East) since the seventh century and had been introduced in several dioceses in the West as well, even though the philosophical basis was lacking. Citing Anselm of Canterbury's principle, "potuit, decuit, ergo fecit" (God could do it, it was appropriate, therefore he did it), Duns Scotus devised the following argument: Mary was in need of redemption like all other human beings, but through the merits of Jesus' crucifixion, given in advance, she was conceived without the stain of original sin. God could have brought it about (1) that she was never in original sin, (2) she was in sin only for an instant, (3) she was in sin for a period of time, being purged at the last instant. Whichever of these options was most excellent should probably be attributed to Mary.[23] This apparently careful statement provoked a storm of opposition at Paris, and suggested the line 'fired France for Mary without spot' in the famous poem "Duns Scotus's Oxford," by Gerard Manley Hopkins.

This argument appears in Pope Pius IX's declaration of the dogma of the Immaculate Conception. Pope John XXIII recommended the reading of Duns Scotus' theology to modern theology students.
