The religion that is afraid of science dishonors God and commits suicide. . . . Every influx of atheism, of skepticism, is thus made useful as a mercury pill assaulting and removing a diseased religion, and making way for truth.
The first and last lesson of religion is, 'The things that are seen are temporal; the things that are not seen are eternal.' It puts an affront upon nature.

The way of Providence is a little rude. The habit of snake and spider, the snap of the tiger and other leapers and bloody jumpers, the crackle of the bones of his prey in the coil of the anaconda-these are in the system, and our habits are like theirs.
That which shows God in me, fortifies me. That which shows God out of me, makes me a wart and a wen.

Don't set out to teach theism from your natural history... You spoil both.
