"I mean, the piano, of course, but I think the piano should be taught in school just like mathematics, just like reading, writing and arithmetic. I'd say reading, writing, arithmetic and rhythm. But that should be a prerequisite, because then the quality of music in the world at least in the United States, would be much better, if everyone knew something about the piano and about music, they would know this is not good. Right now, there is so much music out that's not good, but no one knows the public doesn't know."

Man is a rational animal—so at least I have been told. … Aristotle, so far as I know, was the first man to proclaim explicitly that man is a rational animal. His reason for this view was … that some people can do sums. … It is in virtue of the intellect that man is a rational animal. The intellect is shown in various ways, but most emphatically by mastery of arithmetic. The Greek system of numerals was very bad, so that the multiplication table was quite difficult, and complicated calculations could only be made by very clever people.
