"Everyone knows what eroticism is. There's no need to talk about it. Everyone has their own sense of the erotic. [..] nothing can live without eroticism, not even insects, they need it too. Only if you have a totally primitive notion of the erotic, of course, that's no good, because I'm always at pains to go beyond the primitive. [..] I need neither a sister nor a mistress. You have all these things within yourself, and sometimes you use it if you feel like it. People always believe that if something is not mentioned directly, it's not there, but that's nonsense. An eighty-year-old man who's in bed somewhere and who hasn't had this love you're talking about for fifty years, he too has a sexual life. On the contrary, his is a much more amazing kind of sexual existence than the primitive. I prefer to see a dog doing it, where I can watch and stay strong."
