One cannot refute what one has not thoroughly understood.

The most superficial fact regarding the 'Discourses,' the fact that the number of its chapters equals the number of books of Livy's 'History,' compelled us to start a chain of tentative reasoning which brings us suddenly face to face with the only New Testament quotation that ever appears in Machiavelli's two books and with an enormous blasphemy.

Life is too short to live with any but the greatest books.

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.

Nothing ought to be said or done which could create the impression that unbiased reconsideration of the most elementary premises of philosophy is a merely academic or historical affair.

To 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.

Men are constantly attracted and deluded by two opposite charms: the charm of competence which is engendered by mathematics and everything akin to mathematics, and the charm of humble awe, which is engendered by meditation on the human soul and its experiences. Philosophy is characterized by the gentle, if firm, refusal to succumb to either charm.
