The most terrifying fact of the universe is not that it is hostile but that it is indifferent; but if we can come to terms with this indifference and accept the challenges of life within the boundaries of death — however mutable man may be able to make them — our existence as a species can have genuine meaning and fulfillment.

However vast the darkness, we must supply our own light.

This is one of the most beautiful and true things I have ever read.
