In the last decade or two there has grown up in this country, principally under the leadership of Professor Milton Friedman, a school calling itself the Monetarists. The leaders sometimes sum up their doctrine in the phrase: "Money matters," and even sometimes in the phrase: "Money matters most."

The dilemma is this. In the modern world knowledge has been growing so fast and so enormously, in almost every field, that the probabilities are immensely against anybody, no matter how innately clever, being able to make a contribution in any one field unless he devotes all his time to it for years. If he tries to be the Rounded Universal Man, like Leonardo da Vinci, or to take all knowledge for his province, like Francis Bacon, he is most likely to become a mere dilettante and dabbler. But if he becomes too specialized, he is apt to become narrow and lopsided, ignorant on every subject but his own, and perhaps dull and sterile even on that because he lacks perspective and vision and has missed the cross-fertilization of ideas that can come from knowing something of other subjects.

If the money was raised by taxation, we saw, then for every dollar that the government spent on public works one less dollar was spent by the taxpayers to meet their own wants, and for every public job created one private job was destroyed.
