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.
— Henri Poincar?, Science and Method

For this will cure him that is sick,

For this will cure him that is sick, and rouse him that is in dumps; one that has loved, it will remember of it; one that has not, it will instruct. For there was never any yet that wholly could escape love, and never shall there be any, never so long as beauty shall be, never so long as eyes can see. But help me that God to write the passions of others; and while I write, keep me in my own right wits.
