The contemporary rejection of natural right leads to nihilism - nay, it is identical with nihilism.
Leo StraussThe emancipation of the scholars and scientists from philosophy is according to [Nietzsche] only a part of the democratic movement, i.e. of the emancipation of the low from subordination to the high. ...

Leo StraussMen 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.

As regards the most weighty matters the first things and the right way the only source of knowledge was hearsay.
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.
