Slavoj Žižek:
“One should introduce the distinction between pleasure and enjoyment elaborated by the psychoanalyst Jacques Lacan: what Lacan calls jouissance (enjoyment) is a deadly excess beyond pleasure, which is by definition moderate. We thus have two extremes: on the one hand the enlightened hedonist who carefully calculates his pleasures to prolong his fun and avoid getting hurt, on the other the jouisseur propre, ready to consummate his very existence in the deadly excess of enjoyment – or, in the terms of our society, on the one hand the consumerist calculating his pleasures, well protected from all kinds of harassments and other health threats, on the other the drug addict or smoker bent on self-destruction. Enjoyment is what serves nothing, and the great effort of today’s hedonist-utilitarian “permissive” society is to tame and exploit this un(ac)countable excess into the field of (ac)counting.
Enjoyment is tolerated, solicited even, but on condition that it is healthy, that it doesn’t threaten our psychic or biological stability: chocolate, yes, but fat-free; Coke, yes, but diet; coffee, yes, but without caffeine; beer, yes, but without alcohol; mayonnaise, yes, but without cholesterol; sex, yes, but safe sex …” (To the full article “Fat-free chocolate and absolutely no smoking: why our guilt about consumption is all-consuming”)
