Man and Animal

[apstudent]

OK, I have a quote in my mind, and I believe someone famous said it. I don't remember it exactly, so help me out please.

"The only thing that separates man from animal is man's ability to_____."

Please, correct any part of it and help with the original author.

I found one site (not a quote site) containing the following text:

"The only thing that separates man from animal is man's ability to conceptualize the perceptions."

Other possibilities to fill the blank: imagine, love, and create. Can't help ya' in regards to the author.

Thanx, but anyone with the author. I was thinking that it was love in the slot, but I don't quite remember.
