The scientific observer of the realm of nature is in a sense naturally and inevitably disinterested. At least, nothing in the natural scene can arouse his bias. Furthermore, he stands completely outside of the natural so that his mind, whatever his limitations, approximates pure mind.

God grant me the serenity to accept the things I cannot change, the courage to change the things I can, and the wisdom to know the difference.
