Descartes's Concept of the Self

Summary

René Descartes' concept of the self is rooted in mind-body dualism, asserting that humans consist of a material body and an immaterial mind or soul. He posits that mental states like thinking and imagining are more fundamental to our personhood than physical states. Descartes' famous 'I think, therefore I am' establishes the certainty of one's existence through thought. He argues that while the body is extended and can be deceived, the mind is non-extended and the true self, capable of thought and perception. Descartes suggests the mind and body interact, yet are distinct, with the mind potentially immortal, separate from the body's decay.

Takeaways

• 🧠 Descartes' concept of the self is based on mind-body dualism, suggesting that humans are composed of both a material body and a non-material mind.
• 💭 For Descartes, the mind or soul is superior to the body and is where mental states such as thinking and imagining occur, which are fundamental to our existence as persons.
• 🌟 The famous statement 'I think, therefore I am' (Cogito, ergo sum) by Descartes establishes the certainty of one's existence through the act of thinking.
• 🤔 Descartes argues that the mind is an immaterial substance that thinks and is conscious of itself and its thoughts, making it the true self of humans.
• 🚫 Descartes distinguishes between the clear and distinct ideas of the mind and the body, asserting that they can exist independently of each other.
• 🔍 He uses the wax analogy to demonstrate that it is the mind, not the senses, that distinguishes the essence of things, such as recognizing wax in both solid and melted states.
• 🌐 Descartes views the body as a material entity defined by extension (size, shape, and motion), in contrast to the non-extended nature of the mind.
• 🔑 The mind's ability to perceive and think is central to Descartes' philosophy, with sensation being one of its functions, but true perception belonging to the intellect.
• 🔗 Despite their distinctness, Descartes suggests a union between the mind and body that allows for interaction, with the mind influencing the body and vice versa.
• 💡 Descartes' dualism aims to establish the immortality of the soul, as the decay of the body does not imply the destruction of the soul, based on their separate existence.

Q & A

What is the core idea of Descartes' concept of the self?

Descartes' concept of the self revolves around mind-body dualism, suggesting that a human person is composed of two distinct parts: a material body and a non-material mind or soul.

How does Descartes view the mind in relation to the body?

For Descartes, the mind or soul is superior to the body as it is the seat of mental states such as thinking, imagining, and analyzing, which are fundamental to our existence as persons.

What does Descartes mean by 'extension' in the context of the body?

Descartes uses 'extension' to refer to the material essence of bodies, which includes size, shape, and the ability to endure, be movable, and changeable.

Why does Descartes consider the mind as the real self?

Descartes considers the mind as the real self because it is the thinking entity that makes us human, and it is the mind that one can be certain of, even in the face of doubt.

What is the significance of the statement 'I think, therefore I am' in Descartes' philosophy?

The statement 'I think, therefore I am' (Cogito, ergo sum) is fundamental to Descartes' philosophy as it establishes the certainty of one's own existence through the act of thinking.

How does Descartes differentiate between primary and secondary qualities in the material world?

Descartes differentiates primary qualities, such as size and shape, which are clear and distinct, from secondary qualities like color and taste, which he considers obscure and confused, and not essential to the constitution of a thing.

What role does perception play in Descartes' view of the mind?

In Descartes' view, the mind is capable of both thought and perception. Perception, or sensation, is one of the functions of the mind, but it is the intellect that properly perceives physical objects, not the senses.

How does Descartes explain the interaction between the mind and the body?

Despite the real distinction between mind and body, Descartes argues that they are unified in some sense, allowing for interaction. He suggests that the mind can cause changes in the body and vice versa, although the specifics of this interaction are not clearly defined.

What is the purpose of establishing the distinction between mind and body in Descartes' philosophy?

Establishing the distinction between mind and body allows Descartes to argue for the immortality of the soul, as the decay of the body does not imply the destruction of the soul.

How does Descartes justify the independence of the mind and body?

Descartes justifies the independence of the mind and body through the clear and distinct conceptions of each as complete entities that do not require the qualities of the other to exist.

What is Descartes' explanation for the specific causal relations between mind and body?

Descartes appeals to God to explain the specific causal relations between mind and body, suggesting that God sets up the most conducive relations for the well-being of the composite of mind and body.

🧠 Descartes' Mind-Body Dualism

Descartes' concept of the self is centered on mind-body dualism, where he posits that a human is composed of a material body and a non-material mind or soul. He considers the mind superior to the body as it is the seat of mental states like thinking and imagining, which are fundamental to our existence as persons. Descartes asserts that the mind is the true self and introduces the idea that the mind is an immaterial substance that thinks. He is famous for the statement 'I think, therefore I am,' which he argues is the most certain knowledge one can have. Descartes also discusses the clear and distinct perception of the mind and body as separate entities, setting the stage for the argument of the soul's immortality.

🔍 Perception and the Mind-Body Union

In this paragraph, Descartes explores the nature of perception and its relation to the mind. He argues that while the senses can deceive, the mind's ability to think and reason allows for the correct perception of the world. Using the analogy of wax, he illustrates that it is the mind's thought process, not the senses, that distinguishes between the solid and melted states of wax. Descartes further discusses the interaction between the mind and body, suggesting that despite their distinctness, they are unified in a way that allows for mutual influence. He also touches on the immortality of the soul, suggesting that the body's decay does not imply the soul's destruction. However, when pressed for details on the interaction between mind and body, Descartes defers to the role of God in establishing these relations.

🙏 God's Role in Mind-Body Interaction

The final paragraph delves into Descartes' view on the role of God in the interaction between the mind and body. Descartes suggests that God sets up the causal relations that are most beneficial for the well-being of the composite of mind and body. This divine intervention is what allows for the mind and body to interact despite their inherent differences. Descartes' reliance on the divine to explain the specifics of mind-body interaction highlights his philosophical commitment to the existence of a higher power that governs the natural world and the human experience.

Keywords

💡Mind-Body Dualism

Mind-body dualism is a philosophical concept that posits that the mind and the body are two distinct entities. In the context of Descartes' philosophy, this dualism is central to his understanding of human existence, suggesting that the mind, or soul, is non-material and separate from the physical body. The video script discusses this concept as the foundation of Descartes' view on the self, where the mind's ability to think and reason is what defines humanity, as opposed to the body's physical attributes.

💡Cogito, ergo sum (I think, therefore I am)

This famous phrase, attributed to Descartes, encapsulates his argument for the existence of the self through thought. It is a foundational statement in Western philosophy that asserts the certainty of one's own existence based on the act of thinking. The video script uses this phrase to illustrate Descartes' belief in the indubitable existence of the mind as a thinking entity, even in the face of potential deception by a 'malicious demon'.

💡Res extensa

Res extensa refers to the material aspect of reality, which Descartes believed could be defined by its extension in space, such as size, shape, and motion. In the video, this term is used to contrast the material body with the non-material mind. Descartes considered the body as a mechanical entity, understandable through its physical properties, unlike the mind which is defined by its thoughts and consciousness.

💡Res cogitans

Res cogitans, or 'thinking thing,' is Descartes' term for the immaterial substance of the mind. The video explains that for Descartes, the mind is an entity that thinks, doubts, understands, and wills, and it is through these mental actions that the essence of the self is revealed. This concept is central to Descartes' argument for the mind's existence independent of the body.

💡Clear and distinct perception

This concept refers to the clarity and distinctness of ideas in the mind, which Descartes believed were the basis for certain knowledge. The video script mentions that Descartes relied on clear and distinct perceptions to establish the real distinction between the mind and body. He argued that because we can have a clear and distinct idea of the mind without the body, and vice versa, they must be capable of existing separately.

💡Sensation/Perception

Sensation or perception, as discussed in the video, is the mind's ability to experience and interpret sensory input from the body. Descartes believed that while the senses can be deceived, the act of perceiving is a function of the mind. The video uses the analogy of the wax to illustrate that it is the mind's thought, not the senses, that can truly distinguish between different states of the same object.

💡Intellect

The intellect, in Descartes' philosophy, is the faculty of the mind that allows for understanding and reasoning. The video script explains that, for Descartes, it is the intellect that perceives the true nature of things, not the senses. This is evident in his argument that the mind's reasoning can discern the identity of wax in different states, which the senses alone cannot achieve.

💡Immortality of the soul

Descartes' distinction between the mind and body also leads to his belief in the immortality of the soul. The video script suggests that because the mind (or soul) is a non-material substance, it is not subject to the same decay and corruption as the physical body. This implies that the soul can exist independently of the body, thus supporting the idea of its immortality.

💡Interactionism

Interactionism is the philosophical position that the mind and body, while distinct, can interact with each other. The video explains that Descartes argued for a form of interactionism where the mind can cause changes in the body and vice versa, despite their essential difference. This interaction is what allows for the mind's thoughts to influence physical actions and for physical sensations to be perceived by the mind.

💡Substance

In the context of the video, 'substance' refers to the fundamental nature of reality that underlies all things. Descartes believed in two types of substances: material (res extensa) and immaterial (res cogitans). The video script uses this term to highlight Descartes' argument that both the mind and body are substances, but of entirely different kinds, each with its own distinct properties and modes of existence.

descartes concept

of the self

descartes concept of the self revolves

around the idea of

mind body dualism

for descartes a human person is composed

of two parts

namely a material body and a

non-material

mind it must be noted that

descartes idea of the mind is not

different from the idea

of the soul understood in antiquity for

instance

plato's concept of the soul

for descartes the mind or the soul

is superior to the body for it is in the

mind that mental states occur

this is because for descartes the mental

states

such as thinking imagining and

analyzing rather than the physical

states of the body

such as pain hunger and thirst

are fundamental to our life as persons

in other words for descartes it is

the mind that makes us humans

thus for descartes the mind is

the real self

but how does descartes view the soul as

the true self of humans and how does it

differ from the body

on the one hand descartes understanding

of the body

as a material entity consists in

extension raise extensa

in fact according to descartes all

things in the material world

can be understood and explained in terms

of

size shape and motion

hence to be a body for descartes is

first to have size and shape

second to endure and third

to be movable and changeable

the main reason why descartes puts

premium on extension

as the essence of bodies or material

things

is that the conception of the thing's

extension

such as size and shape is clear

and distinct in other words

one cannot doubt the size and shape of a

thing

for example if one is holding a pen

one cannot doubt that it is tube like

and a bit small

but if we talk about the other purported

features of a thing

such as color and taste descartes says

that they are obscure and confused

hence these attributes do not constitute

a thing

for example the color red is not what

makes a rose truly

a rose a rose flower

can be white or yellow it doesn't have

to be red

for it to be called a rose

well later on john locke calls these

qualities secondary qualities

which for him do not necessarily

constitute the thing

on the other hand as explained in his

second meditation

descartes argues that the mind or soul

is an immaterial non-extended substance

that thinks race cogitans

by thinking descartes means being

conscious of

oneself and the object of its thinking

thus for descartes the mind as the true

self of humans

is a thinking thing

and it is interesting to note that

according to descartes

knowledge of oneself as a subject of

conscious states and acts

is the most certain knowledge anyone can

have

but how does descartes view a thinking

thing

for descartes a thinking thing is

a being that doubts understands

asserts denies wills

imagines and the like

in meditation two of his seminal work

titled

meditations and first philosophy

descartes demonstrates

how certainty can be attained

as already mentioned descartes is

convinced that

he can be certain that he exists

because if he doubts there must be a

thinking mind that does the doubting

thus descartes famously say i think

therefore i am

according to descartes this statement is

injurable

because even if a powerful demon were to

deceive him

into thinking that he does not exist he

needs to exist

in order for the demon to deceive him

therefore whenever descartes thinks

he exists

from here dakot proceeds to addressing

the question

what is this i that does

the thinking descartes however concedes

that

though what he perceives with his senses

may be false

he cannot deny that he is perceiving

thus for descartes the human mind is

capable of both thought and perception

in other words for descartes sensation

or perception belongs to the mind

as a matter of fact sensation is one of

the functions of the mind

descartes uses the analogy of the walks

to prove his

point as we can see

a solid wax and melted walks are

the same walks for some thinkers

such as the empiricists it is the census

that distinguishes a solid wax from a

melted wax

for descartes however the ability to

distinguish

a solid wax from a melted wax

is not the function of the senses but

of thought in other words

it is thought or the reasoning mind

that makes the judgment that the solid

wax

and melted wax are the same walks

for descartes therefore because the

senses

can be deceived physical objects

including bodies

are properly perceived only by the

intellect

indeed for descartes the mind

is the only thing that one can be

certain of

finally descartes believes that the mind

and body are both substances

therefore for descartes mind and body

are completely distinct and that they

are independent from

each other although they are completely

distinct from

each other descartes argues that the

mind

and body are in some sense unified

for descartes this union is what makes

possible

the interaction between mind and body

so despite the real distinction between

mind and body

descartes argues that these substances

nevertheless interact with each other

according to descartes the mind causes

certain changes in the body

and the body in the mind

part of the reason why descartes aims to

establish the distinction between mind

and body

is to establish the fact that the soul

is immortal as we can see

the distinction between mind and body

opens up the possibility

of establishing the immortality of the

soul

since it involves the idea that the

decay

of the body does not imply the

destruction

of the soul but how

does descartes prove the crucial claim

that the mind

and body are capable of existing

apart from each other

here descartes invokes what he calls

first clear and distinct conception of

the mind as a thing

that is complete and does not require

any extended qualities

in order to exist and second

the corresponding clear and distinct

conception of the body

not requiring any mental properties in

order to exist

as we can see descartes real distinction

argument turns on the reliability of

so-called

clear and distinct perception

however descartes did not give a

concrete example of a mind existing

apart from the body and

a body existing apart from the mind

also when asked about the specificity of

this interaction

descartes was unable to answer and

instead

appeal to god

in descripts understanding god sets up

or institutes those particular causal

relations

between mind and body that are in

general

the most conducive to the well-being of

the composite

of mind and body
