There are, of course, inherent tendencies to repetition in music itself. Our poetry, our ballads, our songs are full of repetition; nursery rhymes and the little chants and songs we use to teach young children have choruses and refrains. We are attracted to repetition, even as adults; we want the stimulus and the reward again and again, and in music we get it. Perhaps, therefore, we should not be surprised, should not complain if the balance sometimes shifts too far and our musical sensitivity becomes a vulnerability.

Mathematics is not a deductive science - that's a cliche. When you try to prove a theorem, you don't just list the hypotheses, and then start to reason. What you do is trial and error, experimentation, guesswork.

The major religions on the Earth contradict each other left and right. You can't all be correct. And what if all of you are wrong? It's a possibility, you know. You must care about the truth, right? Well, the way to winnow through all the differing contentions is to be skeptical. I'm not any more skeptical about your religious beliefs than I am about every new scientific idea I hear about. But in my line of work, they're called hypotheses, not inspiration and not revelation.

Hypotheses like professors, when they are seen not to work any longer in the laboratory, should disappear.

This does not mean that the one presenting the hypothesis should be resolute to disbelieve his or her postulate but rather the person should be resolute to leave the expressed opinion should they be thoroughly convinced of its lack of accuracy and poignant truth. Whether this truth is made through poetic license and artistic dramatic presentation or through clinical analysis of facts or both, the truth must be embraced not merely denied by blind faith of either new atheism or religious ideals. New or old is of no consequence, only truth and compassion are of value.

There are apparently two hypotheses about jealousy: that it is a product of civilization and that it is a basic instinct of animals.
