The universe of modern science, in its very 'meaninglessness', involves the gesture of 'traversing the fantasy', of abolishing the dark spot, the domain of the Unexplained which harbours fantasies and thus guarantees Meaning: instead, we get the meaningless mechanism. This is why, for Heidegger, modern science stands for metaphysical 'danger': it poses a threat to the universe of meaning. There is no meaning without some dark spot, without some forbidden/impenetrable domain into which we project fantasies which guarantee our horizon of meaning. Perhaps this very growing disenchantment with our actual social world accounts for the fascination exerted by cyberspace …

I appeal to the philosophers of all countries to unite and never again mention Heidegger or talk to another philosopher who defends Heidegger. This man was a devil. I mean, he behaved like a devil to his beloved teacher [i.e., Husserl ], and he has a devilish influence on Germany. … One has to read Heidegger in the original to see what a swindler he was.

The thing I object to the most about Heidegger was that he was a guru. He practiced philosophy not as a Socratic practice of exchange, where you and I are equal, and it's just a matter of who has the better argument. But no, he was an authority figure, and he fed people's desire to submit themselves to authority. So I think actually his way of teaching was anti-philosophical.

The tenor of Derridian philosophy shares with Heidegger’s a dangerous proclivity towards the bombastic translations of problems of being and knowledge into strident moral dilemmas. Like the cosmic drama of Being repressed by being in Heidegger, Derrida’s protests against phonocentrism sound more like lay sermonizing than genuine analytical argument.

It is rather difficult to describe Heidegger’s face because he could never look straight into one’s eyes for long. His natural expression revealed a reflective brow, an inscrutable countenance, and downcast eyes, which now and again would cast a quick glance to assess the situation. Forced, in conversation, to look one straight in the face, he would appear reserved and insecure, for he lacked the gift of candid communication with other people. Hence his natural expression was one of cautious, peasant-sly mistrust

One can forgive many Germans, but there are some Germans it is difficult to forgive. It is difficult to forgive Heidegger.

What has happened to those who, like Heidegger, have tried to find their ways in immediacy, in intuition, in nature, would be too sad to retell—and is well known anyway. What is certain is that those pathmarks off the beaten track led indeed nowhere.

Ask professional philosophers of today to name the five most significant philosophers of the twentieth century and, whether they love him or loathe him, most will include Heidegger on the list.

When, in the summer of 1953, that is, still during my university studies in Bonn, I read a recently published lecture by Heidegger from the year 1935, the Introduction to Metaphysics, the jargon, the choice of terminology and the style told me at once that the spirit of fascism was manifested in these motives, thoughts and phrases. The book really unsettled me because I had regarded myself up till then as a student of Heidegger. The newspaper article, in which I poured out my great political and philosophical disappointment the same weekend, is therefore entitled: “Thinking with Heidegger against Heidegger”. At the time it was impossible to know that Heidegger had written anti-Semitic letters to his wife as early as 1916 and that he had become a convinced Nazi long before 1933. The fact that he had remained an unrepentant Nazi, however, could be known by 1953 at the latest.

It should be added, perhaps, that the forcefulness of Heidegger's "aristocratic" arguments depends in large part on the personality of the lecturer. One is caught as in a political rally by the slow intensity of his speech. The contemptuous epigrams with which he dismisses the protests of logic or good sense sting the listeners ears with their acidity; and his prophetic solemnity when he invokes the quest for being ties one as spellbound as if one were a novice taking his first steps into the Eleusinian mysteries.
