1 What is it like to be me? Trying to understand consciousness.

2 Socrates “…and the reason, my friend, is this: I am not yet able, as the Delphic inscription has it, to know myself; so it seems to me ridiculous, when I do not yet know that, to investigate irrelevant things.” Plato, Phaedrus

3 Socrates “This man, on one hand, believes that he knows something, while not knowing [anything]. On the other hand, I – equally ignorant – do not believe [that I know anything].” Plato, Apology

4 Descartes But I have convinced myself that there is absolutely nothing in the world, no sky, no earth, no minds, no bodies. Does it now follow that I, too, do not exist? No. If I convinced myself of something [or thought anything at all], then I certainly existed… after considering everything very thoroughly, I must finally conclude that the proposition, I am, I exist, is necessarily true whenever it is put forward by me or conceived in my mind. ( Meditations II)

5 Descartes “I attentively examined what I was, and as I observed that I could suppose that I had no body, and that there was no world or any plaice in which I might be; but that I could not therefore suppose that I was not; and that, on the contrary, from the very circumstances that I thought to doubt the truth of other things, it must clearly and certainly follow that I was…

6 Descartes …I thence concluded that I was a substance whose whole essence or nature consists only in thinking, and which, that it may exist, has need of no place, nor is dependent on any material thing; so that “I,” that is to say, the mind by which I am what I am, is wholly distinct from the body, and is even more easily known that the latter.” (Discourse of Method, Part IV)

7 Descartes’ argument for Dualism. I can doubt that my body exists I cannot doubt that I myself do not exist. Therefore, I myself am totally distinct from my body.

8 Descartes’ Dualism Human Mental stuff Material Stuff

9 Pineal Gland

10 Materialism Everything in the world, including our minds, is made up on matter. That is material physical stuff (energy, mass etc.) Material Stuff

11 Avicenna’s Flying Man Imagine you were created in a perfect state but suspended in mid air, isolated from all sensation (blindfolded, ear’s plugged, not able to smell or taste). Would you be able to affirm the existence of your self?
