“The dislike of philosophy is perennial, and the seeds of the condemnation of Socrates are present at all times”

Introduction to the Bhagavad-Gita (1944)
Context: I have tried to show that the Perennial Philosophy and its ethical corollaries constitute a Highest Common Factor, present in all the major religions of the world. To affirm this truth has never been more imperatively necessary than at the present time. There will never be enduring peace unless and until human beings come to accept a philosophy of life more adequate to the cosmic and psychological facts than the insane idolatries of nationalism and the advertising man’s apocalyptic faith in Progress towards a mechanized New Jerusalem. All the elements of this philosophy are present, as we have seen, in the traditional religions. But in existing circumstances there is not the slightest chance that any of the traditional religions will obtain universal acceptance. Europeans and Americans will see no reason for being converted to Hinduism, say, or Buddhism. And the people of Asia can hardly be expected to renounce their own traditions for the Christianity professed, often sincerely, by the imperialists who, for four hundred years and more, have been systematically attacking, exploiting, and oppressing, and are now trying to finish off the work of destruction by “educating” them. But happily there is the Highest Common Factor of all religions, the Perennial Philosophy which has always and everywhere been the metaphysical system of prophets, saints and sages. It is perfectly possible for people to remain good Christians, Hindus, Buddhists, or Moslems and yet to be united in full agreement on the basic doctrines of the Perennial Philosophy.

Introduction to the Bhagavad-Gita (1944)
Context: The Bhagavad-Gita is perhaps the most systematic scriptural statement of the Perennial Philosophy. To a world at war, a world that, because it lacks the intellectual and spiritual prerequisites to peace, can only hope to patch up some kind of precarious armed truce, it stands pointing, clearly and unmistakably, to the only road of escape from the self-imposed necessity of self-destruction.

1940s, Philosophy for Laymen (1946)
Context: There are a number of purely theoretical questions, of perennial and passionate interest, which science is unable to answer, at any rate at present. Do we survive death in any sense, and if so, do we survive for a time or for ever? Can mind dominate matter, or does matter completely dominate mind, or has each, perhaps, a certain limited independence? Has the universe a purpose? Or is it driven by blind necessity? Or is it a mere chaos and jumble, in which the natural laws that we think we find are only a phantasy generated by our own love of order? If there is a cosmic scheme, has life more importance in it than astronomy would lead us to suppose, or is our emphasis upon life mere parochialism and self-importance? I do not know the answer to these questions, and I do not believe that anybody else does, but I think human life would be impoverished if they were forgotten, or if definite answers were accepted without adequate evidence. To keep alive the interest in such questions, and to scrutinize suggested answers, is one of the functions of philosophy.

Interview (23 September 1966), published posthumously in Der Spiegel (31 May 1976), as translated by Maria P. Alter and John D. Caputo in The Heidegger Controversy : A Critical Reader (1991), edited by Richard Wolin.
Context: Philosophy will not be able to effect an immediate transformation of the present condition of the world. This is not only true of philosophy, but of all merely human thought and endeavor. Only a god can save us. The sole possibility that is left for us is to prepare a sort of readiness, through thinking and poeticizing, for the appearance of the god or for the absence of the god in the time of foundering [Untergang] for in the face of the god who is absent, we founder. Only a God Can Save Us.
