“Revolutions usually begin as replacements for older certainties, and not as pristine discoveries in uncharted terrain.”

“Constrained optimization is the art of compromise between conflicting objectives. This is what design is all about. To find fault with biological design - as Stephen Jay Gould regularly does - because it misses some idealized optimum is therefore gratuitous. Not knowing the objectives of the designer, Gould is in no position to say whether the designer has proposed a faulty compromise among those objectives.”

“We reveal ourselves in the metaphors we choose for depicting the cosmos in miniature.”

“Cultural change works orders of magnitude faster then genetic change. Stephen Jay Gould”

“We pass through this world but once.”

“If I don't make it, I'll be very sad that there are things I didn't do, but I'm happy that I've done what I have.”

“What you see is that the most outstanding feature of life's history is a constant domination by bacteria.”

“With copious evidence ranging from Plato's haughtiness to Beethoven's tirades, we may conclude that the most brilliant people of history tend to be a prickly lot.”

“Death is the ultimate enemy - and I find nothing reproachable in those who rage mightily against the dying of the light.”

“People, as curious primates, dote on concrete objects that can be seen and fondled. God dwells among the details, not in the realm of pure generality. We must tackle and grasp the larger, encompassing themes of our universe, but we make our best approach through small curiosities that rivet our attention - all those pretty pebbles on the shoreline of knowledge. For the ocean of truth washes over the pebbles with every wave, and they rattle and clink with the most wondrous din.”
