Zizek on Viagra

[Peter Kilander]

"The superego inverts the Kantian 'You can, because you must' in a different
way, turning it into 'You must, because you can.' This is the meaning of
Viagra, which promises to restore the capacity of male erection in a purely
biochemical way, bypassing all psychological problems. Now that Viagra can
take care of the erection, there is no excuse: you should have sex whenever
you can; and if you don't you should feel guilty. "
