It is not always easy to diagnose. The simplest form of stupidity - the mumbling, nose-picking, stolid incomprehension - can be detected by anyone. But the stupidity which disguises itself as thought, and which talks so glibly and eloquently, indeed never stops talking, in every walk of life is not so easy to identify, because it marches under a formidable name, which few dare attack. It is called Popular Opinion.

The result of a single action may spread like the circles that expand when a stone is thrown into a pond, until they touch places and people unguessed at by the person who threw the stone.
