History employs evolution to structure biological events in time.

As in 1925, creationists are not battling for religion. They have been disowned by leading church men of all persuasions, for they debase religion even more than they misconstrue science. They are a motley collection to be sure, but their core of practical support lies with the evangelical right, and creationism is a mere stalking horse or subsidiary issue in a political program...The enemy is not fundamentalism; it is intolerance. In this case, the intolerance is perverse since it masquerades under the 'liberal' rhetoric of 'equal time'.

The causes of life's history [cannot] resolve the riddle of life's meaning.

Evolution is one of the two or three most primally fascinating subjects in all the sciences.

Any decent writer writes because there's some deep internal need to keep learning.

Humans are not the end result of predictable evolutionary progress, but rather a fortuitous cosmic afterthought, a tiny little twig on the enormously arborescent bush of life, which if replanted from seed, would almost surely not grow this twig again.

Among people I have met, the few whom I would term “great” all share a kind of unquestioned, fierce dedication; an utter lack of doubt about the value of their activities (or at least an internal impulse that drives through any such angst); and above all, a capacity to work (or at least to be mentally alert for unexpected insights) at every available moment of every day of their lives.
