To rephrase what Cicero wrote of Socrates, Paul called down modern economics from the skies and implanted it in the universities throughout the world. - Michael Szenberg

The Houses of Friedman and Samuelson disagreed on both methodology and policy. Nevertheless, the intellectual battles never encroached upon their personal respect for and friendship to each other.

In contrast to the natural sciences, where Isaac Newton and Albert Einstein made their major contributions, most economics masterpieces were written when the authors were middle aged. Adam Smith, Karl Marx, John Maynard Keynes, and Milton Friedman come to mind. However, Paul started much earlier, in his 20s; and, even now, his new articles influence the fields of economics and finance.

Paul has no problem with wealth, yet he advocates positions that work against his personal economic interests. He notes that, while advocating the closing of tax loopholes, he has no difficulty taking advantage of those that remain. Fundamentally, Paul represents a middle path, as expressed in the ancient dictum that "men with vision walk in the middle."
