Friedrich A. Hayek said this quote

It is because every individual knows little and, in particular, because we rarely know which of us knows best best that we trust the independent and competitive efforts of many to induce the emergence of what we shall want when we see it.

I was quite depressed two weeks ago when I spent an afternoon at Brentano's Bookshop in New York and was looking at the kind of books most people read. Once you see that you lose all hope.

All political theories assume, of course, that most individuals are very ignorant. Those who plead for liberty differ from the rest in that they include among the ignorant themselves as well as the wisest. Compared with the totality of knowledge which is continually utilized in the evolution of a dynamic civilization, the difference between the knowledge that the wisest and that the most ignorant individual can deliberately employ is comparatively insignificant.
