Aristotle first used the term "ethics" to name a field of study developed by his predecessors Socrates and Plato. Philosophical ethics is the attempt to offer a rational response to the question of how humans should best live. Aristotle regarded ethics and politics as two related but separate fields of study, since ethics examines the good of the individual, while politics examines the good of the city-state (Greek polis).
Aristotle's writings have been read more or less continuously since ancient times, and his ethical treatises in particular continue to influence philosophers working today. Aristotle emphasized the importance of developing excellence (virtue) of character (Greek ethikē aretē), as the way to achieve what is finally more important, excellent activity (Greek energeia). As Aristotle argues in Book II of the Nicomachean Ethics, the man who possesses character excellence does the right thing, at the right time, and in the right way. Bravery, and the correct regulation of one's bodily appetites, are examples of character excellence or virtue. So acting bravely and acting temperately are examples of excellent activities. The highest aims are living well and eudaimonia a Greek word often translated as well-being, happiness or "human flourishing". Like many ethicists, Aristotle regards excellent activity as pleasurable for the man of virtue. For example, Aristotle thinks that the man whose appetites are in the correct order actually takes pleasure in acting moderately.
Aristotle emphasized that virtue is practical, and that the purpose of ethics is to become good, not merely to know. Aristotle also claims that the right course of action depends upon the details of a particular situation, rather than being generated merely by applying a law. The type of wisdom which is required for this is called "prudence" or "practical wisdom" (Greek phronesis), as opposed to the wisdom of a theoretical philosopher (Greek sophia). But despite the importance of practical decision making, in the final analysis the original Aristotelian and Socratic answer to the question of how best to live, at least for the best types of human, was to live the life of philosophy.
Three ethical treatises
Three Aristotelian ethical works survive today which are considered to be either by Aristotle, or from relatively soon after:
- Nicomachean Ethics, abbreviated as the NE or sometimes (from the Latin version of the name) as the EN. The NE is in 10 books, and is the most widely read of Aristotle's ethical treatises.
- Eudemian Ethics, often abbreviated as the EE.
- Magna Moralia, often abbreviated as the MM.
The exact origins of these texts is unclear, although they were already considered the works of Aristotle in ancient times. Textual oddities suggest that they may not have been put in their current form by Aristotle himself. For example, Books IV-VI of Eudemian Ethics also appear as Books V-VII of Nicomachean Ethics. The authenticity of the Magna Moralia has been doubted, whereas almost no modern scholar doubts that Aristotle wrote the Nicomachean Ethics and the Eudemian Ethics himself, even if an editor also played some part in giving us those texts in their current forms.
The Nicomachean Ethics has received the most scholarly attention, and is the most easily available to modern readers in many different translations and editions. Some critics consider the Eudemian Ethics to be "less mature," while others, such as Kenny (1978), contend that the Eudemian Ethics is the more mature, and therefore later, work.
Traditionally it was believed that the Nicomachean Ethics and the Eudemian Ethics were either edited by or dedicated to Aristotle's son and pupil Nicomachus and his disciple Eudemus, respectively, although the works themselves do not explain the source of their names. Although Aristotle's father was also called Nicomachus, Aristotle's son was the next leader of Aristotle's school, the Lyceum, and in ancient times he was already associated with this work.
A fourth treatise, Aristotle's Politics, is often regarded as the sequel to the Ethics, in part because Aristotle closes the Nicomachean Ethics by saying that his ethical inquiry has laid the groundwork for an inquiry into political questions (NE X.1181b6-23). Aristotle's Ethics also states that the good of the individual is subordinate to the good of the city-state, or polis.
Fragments also survive from Aristotle's Protrepticus, another work which dealt with ethics.
Aristotle as a Socratic
Some scholars regarded Aristotle as a Socratic thinker. Aristotle's ethics builds upon earlier Greek thought, particularly that of his teacher Plato and Plato's teacher, Socrates. While Socrates left no written works, and Plato wrote dialogues and a few letters, Aristotle wrote treatises in which he sets forth philosophical doctrines directly. To be more precise, Aristotle did write dialogues, but they unfortunately survive only in fragments.
According to Aristotle in his Metaphysics, Socrates was the first Greek philosopher to concentrate on ethics, although he apparently did not give it this name, as a philosophical inquiry concerning how people should best live. Aristotle dealt with this same question but giving it two names, "the political" (or Politics) and "the ethical" (Ethics), both with Politics being the name for the two together as the more important part. The original Socratic questioning on ethics started at least partly as a response to sophism, which was a popular style of education and speech at the time. Sophism emphasized rhetoric, and argument, and therefore often involved criticism of traditional Greek religion and flirtation with moral relativism.
Aristotle's ethics, or study of character, is built around the premise that people should achieve an excellent character (a virtuous character, "ethikē aretē" in Greek) as a pre-condition for attaining happiness or well-being (eudaimonia). It is sometimes referred to in comparison to later ethical theories as a "character based ethics". Like Plato and Socrates he emphasized the importance of reason for human happiness, and that there were logical and natural reasons for humans to behave virtuously, and try to become virtuous.
Aristotle's treatment of the subject is distinct in several ways from that found in Plato's Socratic dialogues.
- Aristotle's presentation is obviously different from Plato's because he does not write in dialogues, but in treatises. Apart from this difference, Aristotle explicitly stated that his presentation was different from Plato's because he started from whatever could be agreed upon by well brought-up gentlemen, and not from any attempt to develop a general theory of what makes anything good. He explained that it was necessary not to aim at too much accuracy at the starting point of any discussion to do with controversial matters such as those concerning what is just or what is beautiful. (From this starting point however, he built up to similar theoretical conclusions concerning the importance of intellectual virtue and a contemplative life.)
- Rather than discussing only four "cardinal virtues" of Plato (courage, temperance, justice, and prudence), all three of the ethical works, starts with courage and temperance as the two typical moral virtues which can be described as a mean, then discusses a whole range of minor virtues and vices which can be described as a mean, and only then discusses justice and the intellectual virtues. Aristotle places prudence (phronēsis, often translated as practical wisdom) amongst these intellectual virtues. (Nevertheless, like Plato he eventually says that all the highest forms of the moral virtues require each other, and all require intellectual virtue, and in effect that the happiest and most virtuous life is that of a philosopher.)
- Aristotle emphasizes throughout all his analyses of virtues that they aim at what is beautiful (kalos), effectively equating the good, at least for humans, with the beautiful (to kalon).
- Aristotle's analysis of ethics makes use of his metaphysical theory of potentiality and actuality. He defines happiness in terms of this theory as an actuality (energeia); the virtues which allow happiness (and enjoyment of the best and most constant pleasures) are dynamic-but-stable dispositions (hexeis) which are developed through habituation; and this pleasure in turn is another actuality that compliments the actuality of happy living.
Aristotle believed that ethical knowledge is not only a theoretical knowledge, but rather that a person must have "experience of the actions in life" and have been "brought up in fine habits" to become good (NE 1095a3 and b5). For a person to become virtuous, he can't simply study what virtue is, but must actually do virtuous things.
|“||We are not studying in order to know what virtue is, but to become good, for otherwise there would be no profit in it. (NE II.2)||”|
Aristotle's starting point
The Aristotelian Ethics all aim to begin with approximate but uncontroversial starting points. In the Nicomachean Ethics Aristotle says explicitly that one must begin with what is familiar to us, and "the that" or "the fact that" (NE I.1095b2-13). Ancient commentators agree that Aristotle means here that his treatise must rely upon practical, everyday knowledge of virtuous actions as the starting points of his inquiry, and that he is supposing that his readers will have some kind of experienced understanding of such actions, and value noble and just actions to at least some degree.
Elsewhere, Aristotle also seems to rely upon common conceptions of how the world works. In fact, some regard his ethical inquiries as using a method that relies upon popular opinion (his so-called "endoxic method" from the Grk. endoxa). There is some dispute, however, about exactly how such common conceptions fit into Aristotle's method in his ethical treatises, particularly since he also makes use of more formal arguments, especially the so-called "function argument," which is described below.
Aristotle describes popular accounts about what life would be happy as dividing into three most common types: a life dedicated to vulgar pleasure; a life dedicated to fame and honor; or a life dedicated to contemplation (NE I.1095b17-19). To reach his own conclusion about the best life, however, Aristotle tries to isolate the function of humans. The argument he develops here is accordingly widely known as "the function argument," and is among the most-discussed arguments made by any ancient philosopher. He argues that while humans undergo nutrition and growth, so do other living things, and while humans are capable of perception, this is shared with animals (NE I.1098b22-1098a15). Thus neither of these characteristics is particular to humans. According to Aristotle, what remains and what is distinctively human is reason. Thus he concludes that the human function is some kind of excellent exercise of the intellect. And, since Aristotle thinks that practical wisdom rules over the character excellences, exercising such excellences is one way to exercise reason and thus fulfill the human function.
One common objection to Aristotle's function argument is that it uses descriptive or factual premises to derive conclusions about what is good. Such arguments are often thought to run afoul of the is-ought gap.
Moral virtue, or excellence of character, is the disposition (Grk hexis) to act excellently, which a person develops partly as a result of his upbringing, and partly as a result of his habit of action. Aristotle develops his analysis of character in Book II of the Nicomachean Ethics, where he makes this argument that character arises from habit—likening ethical character to a skill that is acquired through practice, such as learning a musical instrument. In Book III of the Nicomachean Ethics, Aristotle argues that a person's character is voluntary, since it results from many individual actions which are under his voluntary control.
Aristotle also claims that each specific character excellence lies between an excess and a deficiency, each of which is a different vice that deviates in some way from the virtuous character state. For example, the man who gets angry too easily is hot-headed, but the man who does not get angry easily enough is soft. This so-called "doctrine of the mean" is one of the best-known aspects of Aristotle's ethics. As Aristotle himself remarks, it is still possible to be "extremely brave," but what this actually means is to be extremely close to the mean. It is also a mistake to suppose that the mean is some mechanical average of the excess and deficiency. For example, Aristotle thinks that knowingly going to one's death is sometimes the right thing to do, but such an action is not moderate in the usual sense of that word.
Aristotle distinguishes the disposition to feel emotions of a certain kind from virtue and vice. But such emotional dispositions may also lie at a mean between two extremes, and these are also to some extent a result of up-bringing and habituation. Two examples of such dispositions would be modesty, or a tendency to feel shame, which Aristotle discusses in NE IV.9; and righteous indignation (nemesis), which is a balanced feeling of sympathetic pain concerning the undeserved pleasures and pains of others. Exactly which habitual dispositions are virtues or vices and which only concern emotions, differs between the different works which have survived, but the basic examples are consistent, as is the basis for distinguishing them in principle.
Some people, despite intending to do the right thing, cannot act according to their own choice. For example, someone may choose to refrain from eating chocolate cake, but finds himself eating the cake contrary to his own choice. Such a failure to act in a way that is consistent with one's own decision is called "akrasia", and may be translated as weakness of will, incontinence, or lack of self-mastery.
Aristotle devotes Book V of the Nicomachean Ethics to justice (this is also Book IV of the Eudemian Ethics). In this discussion, Aristotle defines justice as having two different but related senses—general justice and particular justice. General justice is virtue expressed in relation to other people. Thus the just man in this sense deals properly and fairly with others, and expresses his virtue in his dealings with them—not lying or cheating or taking from others what is owed to them. Particular justice is the correct distribution of just deserts to others. For Aristotle, such justice is proportional—it has to do with people receiving what is proportional to their merit or their worth. In his discussion of particular justice, Aristotle says an educated judge is needed to apply just decisions regarding any particular case. This is where we get the image of the scales of justice, the blindfolded judge symbolizing blind justice, balancing the scales, weighing all the evidence and deliberating each particular case individually.
The highest good
In his ethical works, Aristotle describes eudaimonia as the highest human good. In Book I of the Nicomachean Ethics he goes on to identify eudaimonia as the excellent exercise of the intellect, leaving it open whether he means practical activity or intellectual activity. With respect to practical activity, in order to exercise any one of the practical excellences in the highest way, a person must possess all the others. Aristotle therefore describes several apparently different kinds of virtuous person as necessarily having all the moral virtues, excellences of character.
- Being of "great soul" (magnanimity), the virtue where someone would be truly deserving of the highest praise and have a correct attitude towards the honor this may involve. This is the first such case mentioned in the Nicomachean Ethics.
- Being just in the true sense. This is the type of justice or fairness of a good ruler in a good community.
- Phronesis or practical wisdom, as shown by good leaders.
- The virtue of being a truly good friend.
- Having the nobility kalokagathia of a gentleman.
Aristotle also says, for example in NE Book VI, that such a complete virtue requires intellectual virtue, not only practical virtue, but also theoretical wisdom. Such a virtuous person, if they can come into being, will choose the most pleasant and happy life of all, which is the philosophical life of contemplation and speculation.
Aristotle claims that a human's highest functioning must include reasoning, being good at what sets humans apart from everything else. Or, as Aristotle explains it, "The function of man is activity of soul in accordance with reason, or at least not without reason." He identifies two different ways in which the soul can engage: reasoning (both practical and theoretical) and following reasoning. A person that does this is the happiest because they are fulfilling their purpose or nature as found in the rational soul.
- (The wise person will) be more than human. A man will not live like that by virtue of his humanness, but by virtue of some divine thing within him. His activity is as superior to the activity of the other virtues as this divine thing is to his composite character. Now if mind is divine in comparison with man, the life of the mind is divine in comparison with mere human life. We should not follow popular advice and, being human, have only mortal thoughts, but should become immortal and do everything toward living the best in us. (NE 10.7)
In other words, the thinker is not only the 'best' person, but is also most like God.
Influence on later thinkers
Aristotle's work however continued to be taught as a part of secular education. Aristotle's teachings spread through the Mediterranean and the Middle East, where some early Islamic regimes allowed rational philosophical descriptions of the natural world. Alfarabi was a major influence in all medieval philosophy and wrote many works which included attempts to reconcile the ethical and political writings of Plato and Aristotle. Later Avicenna, and later still Averroes, were Islamic philosophers who commented on Aristotle as well as writing their own philosophy in Arabic. Averroes, a European Muslim, was particularly influential in turn upon European Christian philosophers, theologians and political thinkers.
In the twelfth century, Latin translations of Aristotle's works were made, enabling the Dominican priest Albert the Great and his pupil Thomas Aquinas to synthesize Aristotle's philosophy with Christian theology. Later the medieval church scholasticism in Western Europe insisted on Thomist views and suppressed non-Aristotelian metaphysics. Aquinas' writings are full of references to Aristotle, and he wrote a commentary on Aristotle's Nicomachean Ethics. Aquinas also departed from Aristotle in certain respects. In particular, his Summa Theologica argued that Eudaimonia or human flourishing was held to be a temporary goal for this life, but perfect happiness as the ultimate goal could only be attained in the next life by the virtuous. Aquinas also added new theological virtues were added to Arstotle's system: faith, hope and charity. And supernatural assistance could help people to achieve virtue. Nevertheless, much of Aristotle's ethical thought remained intact in Aquinas.
In modern times, Aristotle's writings on ethics remain among the most influential in his broad corpus, along with The Rhetoric, and The Poetics, while his scientific writings tend to be viewed as of more strictly historical interest. Modern science develops theories about the physical world based on experiments and careful observation—in particular, on the basis of exact measurements of time and distance. Aristotle, on the other hand, bases his science largely on qualitative and non-experimental observation. Accordingly, he made some inaccurate claims which have been overturned—such as the claim that objects of different mass accelerate at different rates due to gravity.
On the other hand, The Nicomachean Ethics continues to be relevant to philosophers today. In fact, Virtue Ethics takes its inspiration from Aristotle's approach to ethics—in particular, sharing his emphasis on character excellence, and ethical psychology. Some philosophers, in particular Bernard Williams, regard Aristotle's ethics as superior to the Utilitarian and Kantian traditions, which have come to be the dominant approaches to philosophical ethics. Aristotle's well-known function argument is less commonly accepted today, since he seems to use it in order to develop a claim about human perfection from an observation from what is distinctive about man. But the exact role of the function argument in Aristotle's ethical theory is itself a matter of dispute.
