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.
