What’s dangerous is not to evolve.

People cited violation of the First Amendment when a New Jersey schoolteacher asserted that evolution and the Big Bang are not scientific and that Noah's ark carried dinosaurs. This case is not about the need to separate church and state; it's about the need to separate ignorant, scientifically illiterate people from the ranks of teachers.

Nothing in biology makes sense except in the light of evolution.

We are going to die, and that makes us the lucky ones. Most people are never going to die because they are never going to be born.

I didn't know what kind of creature I was supposed to be until I woke on a hospital cot and was informed I had died. Nobody ever told me what I was. I figured I was broken. But it turns out that my scars were divine signs that I was granted a chance to begin again.

If your consciousness is without form, without quality, and without characteristics of any kind, would that not imply that the consciousness in every other being is also formless? And if they are all without form, how can you distinguish their consciousness from your own? What forms would you use to compare them? Isn’t the observing you exactly the same as the observing them?

If you seek small things to do, and do them well, great things will seek you, and demand to be performed.

[E]very major religion today is a winner in the Darwinian struggle waged among cultures, and none ever flourished by tolerating its rivals.

If man were infinitely malleable, there would have been nor revolutions; there would have been no change because a culture would have succeeded in making man submit to its patterns without resistance. But man, being only relatively malleable, has always reacted with protest against conditions which made the disequilibrium between the social order and his human needs too drastic or unbearable. The attempt to reduce this disequilibrium and the need to establish a more acceptable and desirable solution is at the very core of the dynamism of the evolution of man in history. Man's protest arose not only because of material suffering; specifically human needs...Are an equally strong motivation for revolution and the dynamics of change.

Permanence of instinct must go with permanence of form...The history of the present must teach us the history of the past.[Referring to studying fossil remains of the weevil, largely unchanged to the present day.].
