Here’s a letter to the Wall Street Journal:
It’s impossible, of course, for any one quotation to adequately capture the essence of the thought of someone who’s contributed so much knowledge and wisdom to humanity as has Mr. Sowell. But a quotation that comes close – one that I never tire of sharing – consists of the final two sentences of Mr. Sowell’s soaring 1980 book, Knowledge and Decisions:
Freedom is not simply the right of intellectuals to circulate their merchandise. It is, above all, the right of ordinary people to find elbow room for themselves and a refuge from the rampaging presumptions of their “betters.” *
No one in the past half-century has done more to help create for ordinary people such a refuge – and to encourage them to take it – than has Thomas Sowell.
