OK, here's a statement that a voice in my head has made: "People are nothing more than a mixture of water, protein, minerals and fat. The so called personality and "soul" are nothing more than merely chemical reactions in the brain- when the brain dies, they die too, just like the sound of musical instruments disappear once the instruments are destroyed, and the electrical signals disappear inside a computer when the computer is switched off or destroyed. No one with a rational mind should have any more pity upon humans than s/he has for a computer. Therefore as a scientist there is no room for passion, or mercy. People are objects, nothing more." Discuss (and please provide evidence for what you're saying: solid evidence like stuff from scientific papers and experiments; or simply flame away).
