The belief that value judgments are not subject, in the last analysis, to rational control, encourages the inclination to make irresponsible assertio… - Leo Strauss

“Our ideas” are only partly our ideas. Most of our ideas are abbreviations or residues of the thought of other people, of our teachers (in the broadest sense of the term) and of our teachers’ teachers; they are abbreviations and residues of the thought of the past. These thoughts were once explicit and in the center of consideration and discussion. It may even be presumed that they were once perfectly lucid. By being transmitted to later generations they have possibly been transformed, and there is no certainty that the transformation was effected consciously and with full clarity. … This means that the clarification of our political ideas insensibly changes into and becomes indistinguishable from the history of political ideas.

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.

For a philosophy based on faith is no longer philosophy. Perhaps it was this unresolved conflict which has prevented Western thought from ever coming to rest. Perhaps it is this conflict which is at the bottom of a kind of thought which is philosophic indeed but no longer Greek: modern philosophy. It is in trying to understand modern philosophy that we come across Machiavelli. Machiavelli is the only political thinker whose name has come into common use for designating a kind of politics, which exists and will continue to exist independently of his influence, a politics guided exclusively by considerations of 'expediency, which uses all means, fair or foul, iron or poison, for achieving its ends-its end being the ag­grandizement of one's country or fatherland-but also using the father­ land in the service of the self-aggrandizement of the politician or statesman or one's party.
