Searle: We need not ponder upon the term ‘mind’ because it does not exist and it is unreal. Sir, you pointed out that mind and body influence each other. At the same time, why don’t you consider that mind is the part of body? I think the study of mind needs a satisfactory conclusion because we are arguing upon an imaginary thing without proof. When you say that the process of though proves the existence of mind, why can’t you say that the same process of thought proves that thought is an inseparable part of brain, which is real?
Descartes: For the sake of argument, please think that you do not exist in this world. You cannot prove your argument because you are real.
