Persons, Minds and Bodies Test One Study Notes The Issues: Indiscernability of Identicals If Clark = Superman , then Clark and Superman have exactly the same properties Transitivity of Identity (1) Clark = Superman (2) Clark = Kal-El (3) Superman = Kal-El The Mind-Body Problem - A man sees the colour green , he likes this shade of green, thinks that he should paint his room green , and has a conscious greenish experience - you could take away the green object and still have this experience - The mind - body problem is that how does the conscious experience relate to the self , the brain or the physical world ? Option One: The mind is one thing, the body is another - the conscious experience makes him say I like that shade of green - or a feeling of pain plays a causal role in making one say “ ouch - we can trace electrical/ chemical activity and it seems for every event or speech act there is a neural cause - what is the point of having the experience if the body does everything ? in this case, the mind is Foating free and makes no difference Option Two: The mind is identical with the body - a blind person asks: what do you see when you experience green ? - the man with sight tries to explain green in the relation to other colours , with the feelings it gives them and explains just how the eye , brian and light work - if you know everything about a bat , you do not know what it is like to be a bat Judith Jarvis Thompson Physical Thesis : People are their bodies Physical Criterion : x=y iff x’s body = y’s body Objections to Physical Criterion: 1.
