The Millions wallops Clive James for his naff biographies.
In light of Sartre's socialist sins, Being and Nothingness is written off here as an update of Heidegger's "high-flown philosophical flapdoodle" the product of "a mind that could not grant itself freedom to speculate in [...] its own compromises with reality." Now, in Heidegger, we have a man whose conduct under totalitarian rule deserves all the opprobrium that can possibly be heaped upon it. But Being and Time cannot be dismissed as "flapdoodle" on the grounds of biography alone. Nor can Being and Nothingness, whose author has the advantage of having participated in the Resistance. In fact, both Sartre and Heidegger were keenly interested in the mind's compromises with reality, though they didn't conceive of it in those terms (see, for example, Being and Time, Part One, Division I, Section V).
It's likely that Heidegger's agnosticism on the subject the Other (later critiqued by that self-interested Witch-Doctor Emmanuel Lewinas) enabled his early political enthusiasm for Hitler. But it's also possible to hang Heidegger out to dry on the grounds of his own definition of authenticity. Sartre, too, for that matter . To the extent that they endorsed or downplayed (respectively) totalitarian regimes, Heidegger and Sartre could be seen to have fallen short of their own philosophies. But to reach this nuanced verdict, one has to have actually tried to understand the philosophies in question, and James can't be bothered with philosophy (not a great quality in a cultural critic). Even Hegel and Kant get his goat. I had always thought of the anti-intellectualism and paranoia as a combination peculiar to the American far right, but apparently it can afflict Aussie humanists, too.
