27 ideas
Democritus says soul consists of smooth round bodies brought together in accidental collision [Democritus, by Cicero]
     Full Idea: Since Democritus makes the soul consist of minute smooth round bodies brought together in some sort of accidental collision, let us pass him over.
     From: report of Democritus (fragments/reports [c.431 BCE]) by M. Tullius Cicero - Tusculan Disputations I.xi.23
     A reaction: If we accept that Democritus thought the collision of atoms 'accidental', then it doesn't sound like a very good theory. What would Cicero say if we replaced 'accidental' with 'naturally selected'?
Atomists say soul has a rational part in the chest, and a diffused non-rational part [Democritus, by Aetius]
     Full Idea: Democritus and Epicurus say the soul has two parts, one which is rational and is situated in the chest area, and the other which is non-rational and is spread throughout the entire compound of the body.
     From: report of Democritus (fragments/reports [c.431 BCE]) by Aetius - fragments/reports 4.4.6
     A reaction: The spread part corresponds to such things as feeling fear in the stomach, or excitement throughout the limbs. I can't think what grounds there would be for choosing the chest as the home of reason. I suppose you can hear reason thumping in there..
The soul is the same as the mind [Democritus, by Aristotle]
     Full Idea: Democritus says the soul is the same thing as the mind.
     From: report of Democritus (fragments/reports [c.431 BCE], A101) by Aristotle - De Anima 405a10
     A reaction: This is not in contrast to the Christian concept of the soul, but in contrast to the normal view of psuché, which is more like the life that permeates the whole body. Democritus was more in tune than Aristotle with modern thought on this.
Soul causes the body to live, and gives it power to breathe and to be revitalized [Plato]
     Full Idea: Those who named the soul thought that when the soul is present in the body, it causes it to live and gives it the power to breathe the air and be revitalized [anapsuchon].
     From: Plato (Cratylus [c.377 BCE], 399d)
     A reaction: I quote this to emphasis that Greek psuché is very different from the consciousness which is largely discussed in modern philosophy of mind. I find it helpful to make a real effort to grasp the Greek concept. The feeling of life within you.
Soul is what is defined by 'self-generating motion' [Plato]
     Full Idea: The entity which we call 'soul' is precisely that which is defined by the expression 'self-generating motion'.
     From: Plato (The Laws [c.348 BCE], 896a)
     A reaction: We may suspect that he defines soul in this way for a particular context, aimed at proving the existence of a First Mover. He must think there is more to soul than the generation of movement.
The soul is self-motion [Plato]
     Full Idea: Self-motion is of the very nature of the soul.
     From: Plato (Phaedrus [c.366 BCE], 245e)
     A reaction: This culminates a length discussion of the soul. He gives an implausible argument that the soul is immortal, because it could never cease its self-motion. Why are we so unimpressed by motion, when the Greeks were amazed by it?
Psychic conflict is clear if appetite is close to the body and reason fairly separate [Plato, by Modrak]
     Full Idea: Plato makes psychic conflict intelligible by appeal to a conception of the soul such that the soul is closely connected to the body at the level of appetite and relatively separate from the body at the level of reason.
     From: report of Plato (The Republic [c.374 BCE], 339b) by Deborah K.W. Modrak - Classical theories of Mind
     A reaction: I'm not sure about this at the level of biology or ontology, but at the phenomenal level this is obviously right. Hunger makes consciousness feel like a physical event, but doing arithmetic doesn't seem remotely physical.
There is a third element to the mind - spirit - lying between reason and appetite [Plato]
     Full Idea: Is the third element of the mind a form of reason, so that there are only two elements to it, reason and appetite? There must be a third element, if spirit ('thumos') can be shown to be distinct - and you can see it in children when they are born.
     From: Plato (The Republic [c.374 BCE], 441a)
     A reaction: This is Plato's famous tripartite doctrine of the soul, though in other dialogues he says that there is only reason and appetite. The suspicion is that he fixed the soul having three parts, to match the three parts of his republic's social structure.
Plato says the soul is ordered by number [Plato, by Plutarch]
     Full Idea: Plato regards the substance of soul not as number but as being ordered by number.
     From: report of Plato (Timaeus [c.349 BCE]) by Plutarch - 68: Generation of the soul in 'Timaeus' 1023
     A reaction: This remark points towards Plato's esoteric doctrines, which are some sort of mathematical metaphysics. The idea that order and numbers are in some way connected is one of the most powerful in western civilization, with undeniable appeal.
Xenocrates held that the soul had no form or substance, but was number [Xenocrates, by Cicero]
     Full Idea: Xenocrates denied that the soul had form or any substance, but said that it was number, and the power of number, as had been held by Pythagoras long before, was the highest in nature.
     From: report of Xenocrates (fragments/reports [c.327 BCE]) by M. Tullius Cicero - Tusculan Disputations I.x.20
     A reaction: This shows how strong the Pythagorean influence was in the Academy. This is not totally stupid. Dawkins holds that the essence of DNA is information, which can be expressed mathematically. Xenocrates was a functionalist.
Aristotle led to the view that there are several souls, all somewhat physical [Aristotle, by Martin/Barresi]
     Full Idea: On the later views inspired by Aristotle's 'De Anima' there was no longer just one soul, but several, and each of them had a great deal in common with the body.
     From: report of Aristotle (De Anima [c.329 BCE]) by R Martin / J Barresi - Introduction to 'Personal Identity' p.17
     A reaction: Is this based on the faculties of sophia, episteme, nous, techne and phronesis, or is it based on the vegetative, appetitive and rational parts? The latter, I presume. Not so interesting, not so modular.
Soul is seen as what moves, or what is least physical, or a combination of elements [Aristotle]
     Full Idea: Three ways have been handed down in which people define the soul: what is most capable of moving things, since it moves itself; or a body which is the most fine-grained and least corporeal; or that it is composed of the elements.
     From: Aristotle (De Anima [c.329 BCE], 409b19)
     A reaction: A nice example of Aristotle beginning an investigation by idenfying the main explanations which have been 'handed down' from previous generations. These three aren't really in competition, and might all be true.
Psuché is the form and actuality of a body which potentially has life [Aristotle]
     Full Idea: Soul is substance as the form of a natural body which potentially has life, and since this substance is actuality, soul will be the actuality of such a body.
     From: Aristotle (De Anima [c.329 BCE], 412a20)
     A reaction: To understand what Aristotle means by 'form' you must, I'm afraid, read the 'Metaphysics'. Form isn't shape, but rather the essence which bestows the individual identity on the thing. 'Psuche is the essence of man' might be a better slogan.
The soul is the cause or source of movement, the essence of body, and its end [Aristotle]
     Full Idea: The soul is the cause [aitia] of its body alike in three senses which we explicitly recognise. It is (a) the source or origin of movement, it is (b) the end, and it is (c) the essence of the whole living body.
     From: Aristotle (De Anima [c.329 BCE], 415b09)
     A reaction: 'Aitia' also means explanation, so these are three ways to explain a human being, by what it does, why what it is for, and by what it intrinsically is. Activity, purpose and nature.
Everything that receives nourishment has a vegetative soul, with it own distinctive excellence [Aristotle]
     Full Idea: One can assume a vegetative part of the soul in everything that receives nourishment, even in embryos; thus the excellence of this faculty is common and not confined to man; ...because of its nature it has no part in human goodness.
     From: Aristotle (Nicomachean Ethics [c.334 BCE], 1102a33)
     A reaction: Presumably the excellences of this part of the soul would be strength, health and appropriate size. If plants have psuché, then neither 'soul' nor 'mind' seem very good translations. 'Vitality' seems a possibility - humans having it in a conscious form.
In a controlled person the receptive part of the soul is obedient, and it is in harmony in the virtuous [Aristotle]
     Full Idea: One element of the soul is irrational but receptive to reason; it struggles and strains against reason. ...In the continent (controlled) man it is obedient to reason, and is more amenable in the virtuous man, as it is in harmony with rational principle.
     From: Aristotle (Nicomachean Ethics [c.334 BCE], 1102b16)
     A reaction: The very core of Aristotle's theory, with an image of psychic harmony derived from Plato (who likens in to a well-tuned musical instrument). Aristotle's merely controlled man ('enkrateia') sounds like Kant's truly moral man, following duty.
The irrational psuché is persuadable by reason - shown by our criticism and encouragement of people [Aristotle]
     Full Idea: That the irrational part of the psuché is in some way persuaded by reason is indicated by our use of admonition, and of reproof and encouragement of all kinds.
     From: Aristotle (Nicomachean Ethics [c.334 BCE], 1102b33)
     A reaction: These attempts to influence people include disapproval of people's feelings, as well as their principles, or their interpretation of the facts. This doesn't prove that feelings can be changed, but it certainly shows that we sometimes want to change them.
If beings are dominated by appetite, this can increase so much that it drives out reason [Aristotle]
     Full Idea: In an irrational being the appetite for what gives it pleasure is insatiable and indiscriminate, and the exercise of the desire increases its innate tendency; and if these appetites are strong and violent, they actually drive out reason.
     From: Aristotle (Nicomachean Ethics [c.334 BCE], 1119b09)
     A reaction: The end-result of this would be a person Aristotle describes as 'brutish'. The remark seems significant because, even though man is essentially a 'rational animal' (man's 'proper function'), it is actually possible to annihilate our reason.
The soul is fine parts distributed through the body, resembling hot breath [Epicurus]
     Full Idea: The soul is a body made up of fine parts distributed throught the entire aggregate, most closely resembling breath with a certain admixture of heat, in one way resembling breath and in another resembling heat
     From: Epicurus (Letter to Herodotus [c.293 BCE], 63)
     A reaction: Remember that 'psuché' refers as much to the life within a creature as it does to the consciousness. The stoics seem to have held a similar view.
Soul is made of four stuffs, giving warmth, rest, motion and perception [Epicurus, by Aetius]
     Full Idea: Epicurus says the soul is a blend of fiery stuff (for bodily warmth), airy stuff (rest), breath (motion), and a nameless stuff (sense-perception).
     From: report of Epicurus (fragments/reports [c.289 BCE]) by Aetius - fragments/reports 4.3.11
     A reaction: Obviously Epicurus thought the four stuffs were different combinations of atoms, rather than being elements. Is there no stuff which gives reason? Reason must reduce to motion, presumably.
The rational soul is in the chest, and the non-rational soul is spread through the body [Epicurus]
     Full Idea: Democritus and Epicurus say the soul has two parts, one which is rational and is situated in the chest area, and the other which is non-rational and is spread throughout the entire compound of the body
     From: Epicurus (fragments/reports [c.289 BCE])
     A reaction: [source Aetius 4.4.6]
Division of the soul divides a person, reducing responsibility for the nonrational part [Stoic school, by Frede,M]
     Full Idea: According to the Stoics, the division of the soul threatens the unity of the person and obscures the responsibility we have for our supposedly nonrational desires.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Michael Frede - A Free Will 3
     A reaction: Does this imply the concept of a 'person', if it places great store by unity? Disagreement over mental unity is one of the great threads running through philosophy. See Nietzsche on 'drives' for the rival view.
Stoics say the soul is a mixture of air and fire [Stoic school, by Galen]
     Full Idea: The Stoic view is clear: the substance of soul comes about through some mixture of air and fire.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Galen - The soul's dependence on the body Kiv.4.784
     A reaction: Most accounts seem to neglect the role of air (whatever that might be).
The soul is the heart, or blood in the heart, or part of the brain, of something living in heart or brain, or breath [Cicero]
     Full Idea: Some think the soul is the heart; Empedocles holds that the soul is blood in the heart; others said one part of the brain claimed the primacy of soul; others say the heart or brain are habitations of the soul; while others identify soul and breath.
     From: M. Tullius Cicero (Tusculan Disputations [c.44 BCE], I.ix.17-19)
     A reaction: A nice survey of views. Note that many of them identify the psuché/anima with physical parts of the body; only the fourth option seems to be dualist. This is despite the contemptuous response to Democritus' atomist theory of soul.
When the soul is intelligent and harmonious, it is part of god and derives from god [Plutarch]
     Full Idea: The soul, when it has partaken of intelligence and reason and concord, is not merely a work but also a part of god and has come to be not by his agency but both from him as source and out of his substance.
     From: Plutarch (67: Platonic Questions [c.85], II.1001)
     A reaction: A most intriguing shift of view from earlier concepts of the psuché. How did this come about? This man is a pagan. The history is in the evolution of Platonism. See 'The Middle Platonists' by John Dillon. Davidson is also very impressed by reason.
Some philosophers say the soul is light [Plutarch]
     Full Idea: Some philosophers hold that the soul is in its essence light.
     From: Plutarch (75: Is 'Live Unknown' a Wise Precept? [c.85], §6)
     A reaction: A nice idea, to rival the stoic view that the soul is fire. It is understandable to propose that the soul is some sort of lightweight and fast moving matter. How else could thought be achieved physically? Nowadays, parallel processing is our only model.
When Aristotle speaks of soul he means something like personality [MacIntyre]
     Full Idea: When Aristotle speaks of the soul we could very often retain his meaning by speaking of personality.
     From: Alasdair MacIntyre (A Short History of Ethics [1967], Ch. 7)
     A reaction: MacIntyre contrasts this strongly with Plato's dualist view. Famously Aristotle thinks the soul is the 'form' of the body, but this implies that he also includes the higher-level functions of the body. Soul is character?
