Those who might be tempted to give way

Those who might be tempted to give way to despair should realize that nothing accomplished in this order can ever be lost, that confusion, error and darkness can win the day only apparently and in a purely ephemeral way, that all partial and transitory disequilibrium must perforce contribute towards the greater equilibrium of the whole, and that nothing can ultimately prevail against the power of truth.

The scientist does not study nature because it

The scientist does not study nature because it is useful to do so. He studies it because he takes pleasure in it, and he takes pleasure in it because it is beautiful. If nature were not beautiful it would not be worth knowing, and life would not be worth living. I am not speaking, of course, of the beauty which strikes the senses, of the beauty of qualities and appearances. I am far from despising this, but it has nothing to do with science. What I mean is that more intimate beauty which comes from the harmonious order of its parts, and which a pure intelligence can grasp.
