It is a curious thing: man, the centre and creator of all science, is the only object which our science has not yet succeeded in including in a homogeneous representation of the universe. We know the history of his bones, but no ordered place has yet been found in nature for his reflective intelligence.

I think that man has a fundamental obligation to extract from himself and from the earth all that it can give; and this obligation is all the more imperative that we are absolutely ignorant of what limits - they may still be very distant - God has imposed on our natural understanding and power.

Progressively saved by the machine from the anxieties that bound his hands and mind to material toil, relieved of a large part of his work and compelled to an ever-increasing speed of action by the devices which his intelligence cannot help ceaselessly creating and perfecting, man is about to find himself abruptly plunged into idleness.

Religion and science are the two conjugated faces or phases of one and the same complete act of knowledge - the only one which can embrace the past and future of evolution and so contemplate, measure and fulfil them.

Thankfully, God's restraining grace keeps even the worst of us from being utterly depraved. The worst people who have ever lived could've been worse.

Faith in reason was the foundation stone of the United States.

God allows unjust disparities between rich and poor because He does not miraculously intervene to establish justice against human wills. Also, discrepancies are not unjust by themselves; justice does not mean equality of result but equality of opportunity.

My characters tend to be more dynamic because they're reaching that point in their lives where their old way of being is breaking down. They're conflicted by the idea that they don't know what's next. You could call it Kierkegaard's leap of faith, when you get tired of sort of reinventing yourself on a very superficial level.
