Most psychiatrists assume that mental illnesses such as depression are caused by chemical imbalances in the brain, which can be treated by drugs. But most psychotherapy doesn't address the social causation of mental illness either.

The 21st century is oppressed by a crushing sense of finitude and exhaustion.

Identity politics is not politics at all, since it precisely negates the political as such by re-construing political positions in ethnic terms, subsuming 'ought' under 'is.'

The reality of nostalgia is nowhere better invoked than at the end of Tarkovsky's 'Solaris.' When the camera pans away from Kelvin embracing his father on the rain-soaked steps of his dacha, we realise that the scene is yet another of the simulations produced by the inscrutable planet.

What is remarkable about Joy Division is the way they are bereft of two of the mainstays of most other rock and pop: longing and supplication.

Nietzsche should not be taken seriously as a political theorist, at least not at the level of his positive prescriptions. But the Nietzsche who denounces the insipidity and mediocrity that result from democracy's levelling impulses could not be more acute.

Christopher Nolan's 'The Prestige' is an enthralling study of doubles, doubling and duplicity. Its twinned themes are obsession and the Secret: the Secret as objet-a, that which inspires, but which can never satisfy, obsession.

OK, so we all know that 'Borat' is humiliatingly, career-endingly unfunny (one trick too many for one-trick pony Sacha Double-Barelled) - but can anyone explain why the 'character' isn't roundly condemned for being as unacceptably racist as the one-dimensional stereotypes from 70s sitcoms such as 'Mind Your Language?'

Reality TV is flat with the anti-cultural imperatives of business: cheap to make, it does ideological work even when it is not giving guru status to dull business people. It fits in with capitalism's anti-mythic myth: the idea that we have liberated ourselves from the dangerous illusions allegedly propagated by art and politics.
