I cannot afford to waste my time making money

The resources of the Deity cannot be so meagre, that, in order to create a human being endowed with reason, he must change a monkey into a man.

The possibilities of existence run so deeply into the extravagant that there is scarcely any conception too extraordinary for Nature to realise.

Embryology furnishes, also, the best measure of true affinities existing between animals.

A laboratory of natural history is a sanctuary where nothing profane should be tolerated. I feel less agony at improprieties in churches than in a scientific laboratory.

The office of science is not to record possibilities; but to ascertain what nature does ... As far as Darwinism deals with mere arguments of possibilities or even probabilities, without a basis of fact, it departs from the true scientific method and injures science, as most of the devotees of the new ism have already done.

I will frankly tell you that my experience in prolonged scientific investigations convinces me that a belief in God-a God who is behind and within the chaos of vanishing points of human knowledge-adds a wonderful stimulus to the man who attempts to penetrate into the regions of the unknown.
