The more we know, the better we realize that our knowledge is a little island in the midst of an ocean of ignorance.

Man is the only living being who has a developed self-awareness and death-awareness.

Seen in retrospect, evolution as a whole doubtless had a general direction, from simple to complex, from dependence on to relative independence of the environment, to greater and greater autonomy of individuals, greater and greater development of sense organs and nervous systems conveying and processing information about the state of the organism's surroundings, and finally greater and greater consciousness.
