However, even if Lacan’s version [“If there is no God, then nothing is permitted”] appears an empty paradox, a quick look at our moral landscape confirms that it is much more appropriate to describe the universe of atheist liberal hedonists: they dedicate their life to the pursuit of pleasures, but since there is no external authority guaranteeing them the space for this pursuit, they become entangled in a thick web of self-imposed Politically Correct regulations, as if a superego much more severe than that of traditional morality is controlling them. They become obsessed by the idea that, in pursuing their pleasures, they may humiliate or violate others’ space, so they regulate their behavior with detailed prescriptions of how to avoid “harassing” others, not to mention the no less complex regulation of their own care of the self (bodily fitness, health food, spiritual relaxation …). Indeed, nothing is more oppressive and regulated than being a simple hedonist.
