"The reason consciousness seems like a mystery to us is that we don't have a clear idea of ​​how anything in the brain could cause conscious states."
 
John Searle
             

“Know thyself” said the oracle of the temple of Delphi and quoted by Socrates 2500 years ago. Yet we have not resolved the fundamental question concerning our true nature. Is consciousness a mere "excretion of the brain" like the liver secretes bile, or is it the manifestation of a spirit capable of surviving after death? This question is undoubtedly one of the most crucial that Humanity can attempt to study scientifically today.
