Men must always have distinguished (e.g. in judicial matters) between hearsay and seeing with one's own eyes and have preferred what one has seen to what he has merely heard from others. But the use of this distinction was originally limited to particular or subordinate matters. As regards the most weighty matters the first things and the right way the only source of knowledge was hearsay.
Leo StraussAll political action aims at either preservation or change. When desiring to preserve, we wish to prevent a change for the worse; when desiring to change, we wish to bring about something better. All political action is then guided by some thought of better or worse.
Leo StraussThe clarification of our political ideas insensibly changes into and becomes indistinguishable from the history of political ideas.
Leo StraussWhen 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 StraussOur understanding of the thought of the past is liable to be the more adequate, the less the historian is convinced of the superiority of his own point of view, or the more he is prepared to admit the possibility that he may have to learn something, not merely about the thinkers of the past, but from them.
