Democracy in its human sense is not arbitrament by the majority; it is not even arbitrament by everybody.

Context

“Now this masculine love of an open and level camaraderie is the life within all democracies and attempts to govern by debate; without it the republic would be a dead formula. Even as it is, of course, the spirit of democracy frequently differs widely from the letter, and a pothouse is often a better test than a Parliament. Democracy in its human sense is not arbitrament by the majority; it is not even arbitrament by everybody. It can be more nearly defined as arbitrament by anybody. I mean that it rests on that club habit of taking a total stranger for granted, of assuming certain things to be inevitably common to yourself and him.” source
