When speaking of a "body of knowledge" or of "the results of research," e.g., we tacitly assign the same cognitive status to inherited knowledge and to independently acquired knowledge. To counteract this tendency a special effort is required to transform inherited knowledge into genuine knowledge by revitalizing its original discovery, and to discriminate between the genuine and the spurious elements of what claims to be inherited knowledge.
Leo StraussThe belief that value judgments are not subject, in the last analysis, to rational control, encourages the inclination to make irresponsible assertions regarding right and wrong or good and bad. One evades discussion of serious issues by the simple device of passing them off as value problems, whereas, to say the least, many of these conflicts arose out of man's very agreement regarding values.
Leo StraussIt is true that the successful quest for wisdom might lead to the result that wisdom is not the one thing needful. But this result would owe its relevance to the fact that it is the result of the quest for wisdom: the very disavowal of reason must be reasonable disavowal.
Leo StraussTo avert the danger [posed by theory] to life, Nietzsche could choose one of two ways: he could insist on the strictly esoteric character of the theoretical analysis of life - that is, restore the Platonic notion of the noble delusion - or else he could deny the possibility of theory proper and so conceive of thought as essentially subservient to, or dependent on, life or fate... If not Nietzsche himself, at any rate his successors [Heidegger] adopted the second alternative.
Leo StraussWe somehow believe that our point of view is superior, higher than those of the greatest minds either because our point of view is that of our time, and our time, being later than the time of the greatest minds, can be presumed to be superior to their times; or else because we believe that each the greatest minds was right from his point of view, but not, as he claims, simply right.
