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 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.
Leo Strauss
