Body mind and soul Flashcards
What is dualism?
the belief in a separate body and soul
what did plato believe on the soul?
- The soul and the body are separate substances
- At death, the soul separates from the body and returns to the realm of the forms. It resides in the Realm of the Forms until it is born into a new body on earth.
- Plato believed that how a person lives their life now directly impacts on their soul. If they get into bad habits then this will have a negative impact on the soul and its reincarnation in later lives.
How does Plato use the charioteer analogy to define the soul?
-The soul (the charioteer) is made up of the mind (horse one) and the body (horse two).
- The soul represents reason, the mind represents emotion and the body represents appetite.
how does plato view the soul?
- Contains hopes, motives, opinions, and emotions
- Has to keep the body and mind balanced
- The immaterial essence of a person
- Is immortal and unchanging
- Is a source of truth as it contains innate knowledge of the forms
- Must be trained to remember the forms and to be virtuous
- Has the ability to know the truth through reason
How does plato view the body?
- Belongs to the physical world
- Bodily needs can get in the way of the soul’s quest for truth if given too much time
- Is mortal
- I am a body vs I have a body - suggests we are more than a body so it is separate to the soul
How does plato view the mind?
- Needs to be controlled
- Has to recall the realm of the forms
What did descartes argue?
○ Descartes argued that we have a clear and distinct idea of ourselves as a thinking thing
○ He used hyperbolic doubt (extreme doubt) to realise that he could doubt everything except the fact that he was a thinking being as doubt is a form of thought
○ This led him to come up with “I think therefore I am”
○ He believed that the body is divisible but the mind is not, meaning the mind cannot be destroyed as only divisible things can be destroyed.
○ He argued that minds and bodies have different properties so are distinct.
What did descartes believe connected the mind and body?
the pineal gland
How does Leibniz’s law support Descartes?
○ Leibniz’s law says that if two things have exactly the same properties then they are one, not two. If they are different properties then they are two. For Descartes, the mind and body have different properties and so are two distinct things.
What did descartes call physical substances ?
res extensa (as they are extended in space)
What did descartes call mental substances?
res cogitans
How does the Masked man fallacy undermine descartes?
just because you doubt something doesn’t mean it isn’t true
What are the strengths of Plato’s dualism? (5)
- NDEs eg Pam Reynolds
- evidence of innate knowledge (slave boy)
- Past lives show soul reincarnation
- Plato argues that everything in nature has an opposite. e.g. hot is opposite to cold. We only know something is hot because we have experienced cold so one comes from the other. Therefore, death has an opposite life and life’s opposite is death. Death comes from life and life from death.
- Plato argued that the body is divisible but the soul is not. This is because the soul is unseen and so is simple. To destroy something, it had to be broken into parts. As the soul has no parts it can not be destroyed.
What are the weaknesses of Plato’s dualism? (5)
- NDEs explained by lack of oxygen to brain
- no concrete evidence for ROF
- Past lives unreliable - could be made up
- Plenty of things are not brought about by their opposites e.g. black does not bring about white.
- Lacewing - Destruction does not have to come from breaking something into its separate parts. If something has come from nothing (like the soul) then it could be destroyed by being annihilated back to nothing
What are the strengths of Descartes’ dualism? (5)
- Descartes argued that we have a clear and distinct idea of ourselves as a thinking thing and we also have an idea of ourselves as a body which is a non-thinking thing. This shows that we are distinct from our bodies.
- we can often have thoughts without displaying them through our bodies.
- Descartes argues that the body is divisible (I could take my arms and legs off etc.) but the mind is not divisible. This means that the mind cannot be destroyed as only things that are divisible can be destroyed.
- Can doubt body as senses are unreliable, but cannot doubt mind as to doubt it to think
- Descartes argues that minds and bodies have different properties and so are distinct. An essential property of anything existing in space is to have parts, so the body, existing in space must have parts. However, the mind is not in space and therefore has a different property which is thought, it does not have parts. Therefore, mind and body are distinct.
How does Swinburne support Descartes?
He said that it is logically possible to think of ourselves without a body, therefore, we could be without our bodies. For example it is logically possible that we could move objects without using our bodies. If we can be without our bodies, then we are not our bodies.
How does Davies support Descartes?
Davies points out that we often talk about ourselves as though we are not our bodies. For example, we often say that we have a body, not that we are a body. We also recognise that we are the same person over many years, even though our bodies have changed.
What is a weakness of Descartes?
Just because we may talk about ourselves as having a distinct mind and body, it does not follow that we do have a distinct mind and body.
How does Ryle criticise Descartes?
Gilbert Ryle would argue that just thinking something does not mean it is true is a language category mistake. He referred to Descartes mind as the “ghost in the machine”. Descartes is using the term “mind” as though it is separate but really it is a term to cover physical things like our thoughts, personality etc. He has misused language.
How does Davies criticise Descartes? (6)
- Our thoughts about ourselves can be wrong
- Eventually we will show through our bodies what we are thinking.
- Argues how do we know that our mind is not divisible? For Example, if our body is chopped up, how do we know that our mind is not chopped up?
- Argues that just because you doubt something, it does not mean that it is not the case.
- Argues that just because something is logically possible, it does not mean that it is the case. He gives the example that it is logically possible for him to escape death by drowning, but it does not mean that he will escape death by drowning.
- Furthermore, is it possible to conceive of ourselves as disembodied? To be a person is to engage in activities which would be impossible without a body.
How does Hume criticise Descartes/support Davies?
Hume says that we may be aware that we are thinking beings but that does not establish the fact that our thinking is separate to our physical nature.
How does Lacewing criticise Descartes?
- Descartes is presupposing that the mind does exist in this argument. If it does not, then it has no properties and we are just a body.
- Destruction does not just have to be about breaking something down into parts. Destruction can be by annihilation.
Why was Aristotle a monist/soft materialist?
He believes the body and soul depend on each other, so are inseparable
What book did Aristotle write and what did he call the soul in it?
The De Anima - called the soul the psyche
What analogy did Aristotle use to show the body and soul are inseparable?
Imprint in wax analogy - a wax tablet which has been stamped cannot be separated from the impression of the stamp – just as the soul cannot be separated from the body
