I have two luxuries to brood over in my walks, your loveliness and the hour of my death. O that I could have possession of them both in the same minute.
Cats are very independent animals. They're very sexy, if you want. Dogs are different. They're familiar. They're obedient. You call a cat, you go, 'Cat, come here.' He doesn't come to you unless you have something in your hand that he thinks might be food. They're very free animals, and I like that.
It is one thing for the human mind to extract from the phenomena of nature the laws which it has itself put into them; it may be a far harder thing to extract laws over which it has no control.
