Strato of Lampsacus (or Straton; Greek: Στράτων; c. 335 – c. 269 BC) was a Peripatetic philosopher, and the third director (scholarch) of the Lyceum after the death of Theophrastus. He devoted himself especially to the study of natural science, and increased the naturalistic elements in Aristotle's thought to such an extent, that he denied the need for an active god to construct the universe, preferring to place the government of the universe in the unconscious force of nature alone.
Strato, son of Arcesilaus or Arcesius, was born at Lampsacus between 340 and 330 BC. He might have known Epicurus during his period of teaching in Lampsacus between 310 and 306. He attended Aristotle's school in Athens, after which he went to Egypt as tutor to Ptolemy, where he also taught Aristarchus of Samos. He returned to Athens after the death of Theophrastus (c. 287 BC), succeeding him as head of the Lyceum. He died sometime between 270 and 268 BC,.
Strato devoted himself especially to the study of natural science, whence he obtained, or, as it appears from Cicero, assumed the name of Physicus (Greek: Φυσικός). Cicero, while speaking highly of his talents, blames him for neglecting the most important part of philosophy, that which concerns virtue and morals, and giving himself up to the investigation of nature. In the long list of his works, given by Diogenes Laërtius, several of the titles are upon subjects of moral philosophy, but the great majority belong to the department of physical science. None of his writings survive, his views are known only from the fragmentary reports preserved by later writers.
Strato emphasized the need for exact research, and, as an example of this, he made use of the observation of how water pouring from a spout breaks into separate droplets as evidence that falling bodies accelerate.
Whereas Aristotle defined time as the numbered aspect of motion, Strato argued that because motion and time are continuous whereas number is discrete, time has an existence independent of motion. He was critical of Aristotle's concept of place as a surrounding surface, preferring to see it as the space which a thing occupies. He also rejected the existence of Aristotle's fifth element.
He emphasized the role of pneuma, ('breath' or 'spirit') in the functioning of the soul; soul-activities were explained by pneuma extending throughout the body from the 'ruling part' located in the head. All sensation is felt in the ruling-part of the soul, rather than in the extremities of the body; all sensation involves thought, and there is no thought not derived from sensation. He denied that the soul was immortal, and attacked the 'proofs' put forward by Plato in his Phaedo.
Strato believed all matter consisted of tiny particles, but he rejected Democritus' theory of empty space. In Strato's view, void does exist, but only in the empty spaces between imperfectly fitting particles; Space is always filled with some kind of matter. Such a theory permitted phenomena such as compression, and allowed the penetration of light and heat through apparently solid bodies.
The opinions of Strato have given rise too much controversy; but unfortunately the result has been very unsatisfactory on account of lack of information. He seems to have denied the existence of any god outside of the material universe, and to have held that every particle of matter has a plastic and seminal power, but without sensation or intelligence; and that life, sensation, and intellect, are but forms, accidents, and affections of matter.
Nor does his pupil Strato, who is called the natural philosopher, deserve to be listened to; he holds that all divine force is resident in nature, which contains, he says, the principles of birth, increase, and decay, but which lacks, as we could remind him, all sensation and form.
Like the atomists (Leucippus and Democritus) before him, Strato of Lampsacus was a materialist and believed that everything in the universe was composed of matter and energy. Strato was one of the first philosophers to formulate a secular worldview, in which God is merely the unconscious force of nature.
You deny that without God there can be anything: but here you yourself seem to go contrary to Strato of Lampsacus, who concedes to God a pardon from a great task. If the priests of God were on vacation, it is much more just that the Gods would also be on vacation; in fact he denies the need to appreciate the work of the Gods in order to construct the world. All the things that exist he teaches have been produced by nature; not hence, as he says, according to that philosophy which claims these things are made of rough and smooth corpuscles, indented and hooked, the void interfering; these, he upholds, are dreams of Democritus which are not to be taught but dreamt. Strato, in fact, investigating the individual parts of the world, teaches that all that which is or is produced, is or has been produced, by weight and motion. Thus he liberates God from a big job and me from fear.
Strato endeavoured to replace the Aristotelian teleology by a purely physical explanation of phenomena, the underlying elements of which he found in heat and cold, with especially heat as the active principle. Although Strato's view of the universe can be seen as secular, he would probably have accepted the existence of lesser gods within the universe, and in the context of Greek religion it is unlikely that he would have regarded himself as an atheist.
Strabo passes on to the hypothesis of Strato, the natural philosopher, who had observed that the quantity of mud brought down by rivers into the Euxine was so great, that its bed must be gradually raised, while the rivers still continued to pour in an undiminished quantity of water. He therefore conceived that, originally, when the Euxine was an inland sea, its level had by this means become so much elevated that it burst its barrier near Byzantium, and formed a communication with the Propontis, and this partial drainage had already, he supposed, converted the left side into marshy ground, and that, at last, the whole would be choked up with soil. So, it was argued, the Mediterranean had once opened a passage for itself by the Columns of Hercules into the Atlantic, and perhaps the abundance of sea-shells in Africa, near the Temple of Jupiter Ammon, might also be the deposit of some former inland sea, which had at length forced a passage and escaped.
Strato's name meant little in the Middle Ages and the Renaissance, however, in the 17th century his name suddenly became famous because of the supposed similarities between his system and the pantheistic views of Spinoza. Ralph Cudworth, in choosing to attack atheism in 1678, chose Strato's system as one of four types of atheism, and in doing so, coined the term hylozoism to describe any system where primitive matter is endowed with a life-force. These ideas reached Pierre Bayle, who adopted Strato and 'Stratonism' as key components of his own philosophy. In his Continuation des Pensees diverses, published in 1705, Stratonism had become the most important ancient equivalent of Spinozism. For Bayle, Strato had made everything follow a fixed order of necessity, with no innate good or bad in the universe; the universe is not a living thing with intelligence or intent, and there is no other divine power but nature.
