What is man?

What The Sound and the Fury says:

"Man the sum of his climactic experiences Father said. Man the sum of what have you. A problem in impure properties carried tediously to an unvarying nil: stalemate of dust and desire."
"Father said that man is the sum of his misfortunes. One day you'd think misfortune would get tired, but then time is your misfortune Father said. A gull on an invisible wire attached through space dragged. You carry the symbol of your frustration into eternity."
"Father was teaching us that all men are just accumulations dolls stuffed with sawdust swept from the trash heaps where all previous dolls had been thrown away the sawdust flowing from what wound in what side that not for me died not."

What White Noise says:

"But you said we had a situation."
"I didn't say it. The computer did. The whole system says it. It's what we call a massive data-base tally. Gladney, J. A. K. I punch in the name, the substance, the exposure time and then I tap into your computer history. Your genetics, your personals, your medicals, your psychologicals, your police-and-hospitals. It comes back pulsing stars. This doesn't mean anything is going to happen to you as such, at least not today or tomorrow. It just means that you are the sum total of your data. No man escapes that."
"Everything that goes on in your whole life is a result of molecules rushing around somewhere in your brain."
"Heinrich's brain theories. They're all true. We're the sum of our chemical impulses."

Interesting the difference 57 years make.  I wonder what answers the next decades will bring.
