[I]t makes little difference where we draw the line between the pruning and shaping [of behavior] by natural selection which is genetically transmitted to offspring (the wiring you are born with), and the pruning and shaping that later takes place in the individual (the rewiring you end up with, as a result of experience or training). Nature and nurture blend seamlessly together.

Natural selection, the blind, unconscious, automatic process which Darwin discovered, and which we now know is the explanation for the existence and apparently purposeful form of all life, has no purpose in mind. It has no mind and no mind's eye. It does not plan for the future. It has no vision, no foresight, no sight at all. If it can be said to play the role of watchmaker in nature, it is the blind watchmaker.
Richard Dawkins
Professor Eddington has recently remarked that 'The law that entropy always increases - the second law of thermodynamics - holds, I think, the supreme position among the laws of nature'. It is not a little instructive that so similar a law [the fundamental theorem of natural selection] should hold the supreme position among the biological sciences.
Ronald Fisher
No one is without Christianity, if we agree on what we mean by the word. It is every individual's individual code of behavior by means of which he makes him or herself a better human being than their nature wants to be, if they followed their nature only. Whatever its symbol -- cross or crescent or whatever -- that symbol is man's reminder of his duty inside the human race.
William Faulkner
For though ours is a godless age, it is the very opposite of irreligious. The true believer is everywhere on the march, and both by converting and antagonizing he is shaping the world in his own image. And whether we are to line up with him or against him, it is well that we should know all we can concerning his nature and potentialities.
Eric Hoffer
Our whole life can go on in observation of the laws of nature, if we gain dominion over our desires from the beginning and if we do not kill, by various means of a perverse art, the human offspring, born according to the designs of divine providence; for these women who, in order to hide their immorality, use abortive drugs which expel the child completely dead, abort at the same time their own human feelings.
