In Kant’s description, ethical duty functions like a foreign traumatic intruder that from the outside disturbs the subject’s homeostatic balance, its unbearable pressure forcing the subject to act “beyond the pleasure principle,” ignoring the pursuit of pleasures. For Lacan, exactly the same description holds for desire, which is why enjoyment is not something that comes naturally to the subject, as a realization of her inner potential, but is the content of a traumatic superego injunction.
