An empty stomach knows no morality. - Pierre-Joseph Proudhon

Yes: all men believe and repeat that equality of conditions is identical with equality of rights; that property and robbery are synonymous terms; that every social advantage accorded, or rather usurped, in the name of superior talent or service, is iniquity and extortion. All men in their hearts, I say, bear witness to these truths; they need only to be made to understand it.

...if there be some points which correspondence can never settle, but which can be made clear by conversation in two minutes, at other times just the opposite is the case: an objection clearly stated in writing, a doubt well expressed, which elicits a direct and positive reply, helps things along more than ten hours of oral intercourse!

For me, the response is simple. All ideas are false, that is to say contradictory and irrational, if one takes them in an exclusive and absolute sense, or if one allows oneself to be carried away by that sense; all are true, susceptible to realization and use, if one takes them together with others, or in evolution.
