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.

If old truths are to retain their hold on men’s minds, they must be restated in the language and concepts of successive generations. What at one time are their most effective expressions gradually become so worn with use that they cease to carry a definite meaning. The underlying ideas may be as valid as ever, but the words, even when they refer to problems that are still with us, no longer convey the same conviction; the arguments do not move in a context familiar to us; and they rarely give us direct answers to the questions we are asking This may be inevitable because no statement of an ideal that is likely to sway men’s minds can be complete: it must be adapted to a given climate of opinion, presuppose much that is accepted by all men of the time, and illustrate general principles in terms of issues with which they are concerned.
