{{about|the concept of hylomorphism in Aristotelian philosophy|the concept in computer science|Hylomorphism (computer science)}}Hylomorphism (or hylemorphism) is a philosophical theory developed by Aristotle, which conceives (wiktionary:being|being) (ousia) as a compound of matter and form. The word is a 19th-century term formed from the Greek words ὕλη hyle, "wood, matter", and μορφή, morphē, "form".

Matter and form

{{further|Aristotle's biology}}Aristotle defines X's matter as "that out of which" X is made.Physics 194b23-24 For example, letters are the matter of syllables.Physics 195a16 Thus, "matter" is a relative term:Physics 194b9 an object counts as matter relative to something else. For example, clay is matter relative to a brick because a brick is made of clay, whereas bricks are matter relative to a brick house.Change is analyzed as a material transformation: matter is what undergoes a change of form.Robinson 18-19 For example, consider a lump of bronze that's shaped into a statue. Bronze is the matter, and this matter loses one form (that of a lump) and gains a new form (that of a statue).Physics 195a6-8Metaphysics 1045a26-29According to Aristotle's theory of perception, we perceive an object by receiving its form with our sense organs.On the Soul 424a19 Thus, forms include complex qualia such as colors, textures, and flavors, not just shapes.On the Soul 418a11–12

Substantial form, accidental form, and prime matter

{{See also|Substantial form}}Medieval philosophers who used Aristotelian concepts frequently distinguished between substantial forms and accidental forms. A substance necessarily possesses at least one substantial form. It may also possess a variety of accidental forms. For Aristotle, a "substance" (ousia) is an individual thing—for example, an individual man or an individual horse.Categories 2a12-14 The substantial form of substance S consists of S's essential properties,Cross 34 the properties that S's matter needs in order to be the kind of substance that S is.Kenny 24 In contrast, S's accidental forms are S's non-essential properties,Cross 94 properties that S can lose or gain without changing into a different kind of substance.Kenny 24In some cases, a substance's matter will itself be a substance. If substance A is made out of substance B, then substance B is the matter of substance A. However, what is the matter of a substance that is not made out of any other substance? According to Aristotelians, such a substance has only "prime matter" as its matter. Prime matter is matter with no substantial form of its own.Leftow 136-37 Thus, it can change into various kinds of substances without remaining any kind of substance all the time.Kenny 25

Body–soul hylomorphism

Basic theory

{{See also|On the Soul|Aristotle's biology}}Aristotle applies his theory of hylomorphism to living things. He defines a soul as that which makes a living thing alive.On the Soul 413a20-21 Life is a property of living things, just as knowledge and health are.On the Soul 414a3-9 Therefore, a soul is a form—that is, a specifying principle or cause—of a living thing.On the Soul 412a20, 414a15-18 Furthermore, Aristotle says that a soul is related to its body as form to matter.On the Soul 412b5-7, 413a1-3, 414a15-18Hence, Aristotle argues, there is no problem in explaining the unity of body and soul, just as there is no problem in explaining the unity of wax and its shape.412b5-6 Just as a wax object consists of wax with a certain shape, so a living organism consists of a body with the property of life, which is its soul. On the basis of his hylomorphic theory, Aristotle rejects the Pythagorean doctrine of reincarnation, ridiculing the notion that just any soul could inhabit just any body.On the Soul 407b20-24, 414a22-24According to Timothy Robinson, it is unclear whether Aristotle identifies the soul with the body's structure.Robinson 45-47 According to one interpretation of Aristotle, a properly organized body is already alive simply by virtue of its structure.Robinson 46 However, according to another interpretation, the property of life—that is, the soul—is something in addition to the body's structure. Robinson uses the analogy of a car to explain this second interpretation. A running car is running not only because of its structure but also because of the activity in its engine.Robinson 46 Likewise, according to this second interpretation, a living body is alive not only because of its structure but also because of an additional property: the soul, which a properly organized body needs in order to be alive.Robinson 47 John Vella uses Frankenstein's monster to illustrate the second interpretation:Vella 92 the corpse lying on Frankenstein's table is already a fully organized human body, but it is not yet alive; when Frankenstein activates his machine, the corpse gains a new property, the property of life, which Aristotle would call the soul.

Living bodies

Some scholars have pointed out a problem facing Aristotle's theory of soul-body hylomorphism.Shields, Aristotle 290-93 According to Aristotle, a living thing's matter is its body, which needs a soul in order to be alive. Similarly, a bronze sphere's matter is bronze, which needs roundness in order to be a sphere. Now, bronze remains the same bronze after ceasing to be a sphere. Therefore, it seems that a body should remain the same body after death.Shields, Aristotle 291 However, Aristotle implies that a body is no longer the same body after death.On the Soul 412b19-24 Moreover, Aristotle says that a body that has lost its soul is no longer potentially alive.412b15 But if a living thing's matter is its body, then that body should be potentially alive by definition.One approach to resolving this problemShields, Aristotle 293 relies on the fact that a living body is constantly replacing old matter with new. A five-year-old body consists of different matter than does the same person's seventy-year-old body. If the five-year-old body and the seventy-year-old body consist of different matter, then what makes them the same body? The answer is presumably the soul. Because the five-year-old and the seventy-year-old bodies share a soul—that is, the person's life—we can identify them both as the body. Apart from the soul, we cannot identify what collection of matter is the body. Therefore, a person's body is no longer that person's body after it dies.Another approach to resolving the problemShields, "A Fundamental Problem" relies on a distinction between "proximate" and "non-proximate" matter. When Aristotle says that the body is matter for a living thing, he may be using the word "body" to refer to the matter that makes up the fully organized body, rather than the fully organized body itself. Unlike the fully organized body, this "body" remains the same thing even after death. In contrast, when he says that the body is no longer the same after its death, he is using the word "body" to refer to the fully organized body.

Intellect

{{See also|Nous|Active intellect|Passive intellect}}Aristotle says that the intellect (nous), the ability to think, has no bodily organ (in contrast with other psychological abilities, such as sense-perception and imagination).On the Soul 429a26-27 In fact, he says that it is not mixed with the bodyOn the Soul 429a24-25 and suggests that it can exist apart from the body.On the Soul 413b24-26, 429b6 This seems to contradict Aristotle's claim that the soul is a form or property of the body. To complicate matters further, Aristotle distinguishes between two kinds, or two parts, of intellect.On the Soul 15-25'' These two intellectual powers are traditionally called the "passive intellect" and the "active (or agent) intellect".Robinson 50 Thus, interpreters of Aristotle have faced the problem of explaining how the intellect fits into Aristotle's hylomorphic theory of the soul.According to one interpretation, a person's ability to think (unlike his other psychological abilities) belongs to some incorporeal organ distinct from his body.Caston, "Aristotle's Psychology" 337 This would amount to a form of dualism.Caston, "Aristotle's Psychology" 337 However, according to some scholars, it would not be a full-fledged Cartesian dualism.Shields, "Some Recent Approaches" 165 This interpretation creates what Robert Pasnau has called the "mind-soul problem": if the intellect belongs to an entity distinct from the body, and the soul is the form of the body, then how is the intellect part of the soul?Pasnau 160Another interpretation rests on the distinction between the passive intellect and the agent intellect. According to this interpretation, the passive intellect is a property of the body, while the agent intellect is a substance distinct from the body.McEvilley 534Vella 110 Some proponents of this interpretation think that each person has his own agent intellect, which presumably separates from the body at death.Caston, "Aristotle's Two Intellects" 207Vella 110 Others interpret the agent intellect as a single divine being, perhaps the unmoved mover, Aristotle's God.Caston, "Aristotle's Psychology" 339Caston, "Aristotle's Two Intellects" 199A third interpretationShields, "Soul as Subject" relies on the theory that an individual form is capable of having properties of its own.Shields, "Soul as Subject" 142 According to this interpretation, the soul is a property of the body, but the ability to think is a property of the soul itself, not of the body. If that is the case, then the soul is the body's form and yet thinking need not involve any bodily organ.Shields, "Soul as Subject" 145

Universal hylomorphism

The Neoplatonic philosopher Avicebron (a.k.a.Solomon Ibn Gabirol) proposed a Neoplatonic version of this Aristotelian concept, according to which all things, including soul and intellect, are composed of matter and form.ENCYCLOPEDIA

Medieval modifications

Medieval theologians, newly exposed to Aristotle's philosophy, applied hylomorphism to Christian doctrines such as the transubstantiation of the Eucharist's bread and wine into the body and blood of Jesus. Theologians such as Duns Scotus and Thomas Aquinas developed Christian applications of hylomorphism.

Plurality vs. unity of substantial form

Many medieval theologians and philosophers followed Aristotle in seeing a living being's soul as that being's form—specifically, its substantial form. However, they disagreed about whether X's soul is X's only substantial form. Some medieval thinkers argued that X's soul is X's only substantial form, responsible for all of the features of X's body.Kenny 26 In contrast, other medieval thinkers argued that a living being contains at least two substantial forms—(1) the shape and structure of its body, and (2) its soul, which makes its body alive.Cross 70

Thomistic hylomorphism

Thomas Aquinas claimed that X's soul was X's only substantial form, although X also had numerous accidental forms that accounted for X's nonessential features.Stump, "Resurrection, Reassembly, and Reconstitution: Aquinas on the Soul" 161 Aquinas defined a substantial form as that which makes X's matter constitute X, which in the case of a human being is rational capacity.Leftow, "Soul, Mind, and Brain" 397 He attributed all other features of a human being to accidental forms.Stump, "Resurrection, Reassembly, and Reconstitution: Aquinas on the Soul" 165 However, Aquinas did not claim that the soul was identical to the person.Eberl 340 He held that a proper human being is a composite of form and matter, specifically prime matter. Form and matter taken separately may retain some of the attributes of a human being but are nonetheless not identical to that person.Eberl 341 So a dead body is not actually or potentially a human being.Stump, "Resurrection, Reassembly, and Reconstitution: Aquinas on the Soul" 161Eleonore Stump describes Aquinas' theory of the soul in terms of "configuration". The body is matter that is "configured", i.e. structured, while the soul is a "configured configurer". In other words, the soul is itself a configured thing, but it also configures the body.Stump, "Non-Cartesian Substance Dualism and Materialism without Reductionism" 514 A dead body is merely matter that was once configured by the soul. It does not possess the configuring capacity of a human being.Aquinas believed that rational capacity was a property of the soul alone, not of any bodily organ.Stump,"Non-Cartesian Substance Dualism and Materialism without Reductionism" 512 However, he did believe that the brain had some basic cognitive function.Stump, "Non-Cartesian Substance Dualism and Materialism without Reductionism" 512 Aquinas’ attribution of rational capacity to the soul allowed him to claim that disembodied souls could retain their rational capacity, although he was adamant that such a state was unnatural.Stump, "Non-Cartesian Substance Dualism and Materialism without Reductionism" 519

Teleology and ethics

{{See also|Nicomachean Ethics}}Aristotle holds a teleological worldview: he sees the universe as inherently purposeful. Basically, Aristotle claims that potentiality exists for the sake of actuality.Irwin 237 Thus, matter exists for the sake of receiving its form,Metaphysics 1050a15 and an organism has sight for the sake of seeing.Irwin 237 Now, each thing has certain potentialities as a result of its form. Because of its form, a snake has the potential to slither; we can say that the snake ought to slither. The more a thing achieves its potential, the more it succeeds in achieving its purpose.Aristotle bases his ethical theory on this teleological worldview. Because of his form, a human being has certain abilities. Hence, his purpose in life is to exercise those abilities as well and as fully as possible.Nichomachean Ethics 1098a16-18 Now, the most characteristic human ability, which is not included in the form of any other organism, is the ability to think.Nichomachean Ethics 1098a1-5 Therefore, the best human life is a life lived rationally.Nichomachean Ethics 1098a7-8 .....

Modern physics

The idea of hylomorphism can be said to have been reintroduced to the world when Werner Heisenberg invented his duplex world of quantum mechanics. In his 1958 text Physics and Philosophy, Heisenberg states:}}
