A distinctly first-world problem, but no less annoying.
We live in an age in which ideas, important ideas, are worn like articles of fashion.
I would put Facebook activists and armchair social justice warriors in this circle.
We must be careful to make a distinction between the intellectual and the person of intellectual achievement. The two are very, very different animals. There are people of intellectual achievement who increase the sum of human knowledge, the powers of human insight, and analysis. And then there are the intellectuals. An intellectual is a person knowledgeable in one field who speaks out only in others. Starting in the early twentieth century, for the first time an ordinary storyteller, a novelist, a short story writer, a poet, a playwright, in certain cases a composer, an artist, or even an opera singer could achieve a tremendous eminence by becoming morally indignant about some public issue. It required no intellectual effort whatsoever. Suddenly he was elevated to a plane from which he could look down upon ordinary people.
