I can only assume that our social obsession with the representation of the human body only proves its constant position as a major political issue. In the aftermath of the current excess of flesh, we've paradoxically become less tolerant to fleshly thoughts. On the one hand, I feel this attitude mirrors a culture that is far more influenced by religious ethics than by humanities. On the other hand, and since all religions has first condemned women, I would say it reflects this archetypical dichotomy of the Mother/Whore complex: the asexual woman is still the reliable Woman.
In a nutshell, we're becoming more irrational and superstitious although we're becoming more publicly undressed. And, to quote Stevie Wonder, ' 'When you believe in things that you don't understand, then you suffer, Superstition ain't the way''. In the contemporary pursuit of happiness through social connections, fear and suffering conquered rationality. Interestingly, in Greek philosophy, on the antipode of superstition (deisidaimonía, dis for bad + daímōn for spirit, demon) is eudaimonia (eu for good + daímōn for spirit, demon). It describes a state of fulfillment which, unlike happiness, can only be achieved by knowing thyself and becoming, according to Aristotle, one perfect whole (incidentally, this is the first time I've realized the link between Stevie Wonder songs and Aristotle's philosophy!)
Definitely, I don't believe the nude has lost its ability to be subversive - it depends on its context. However, I believe we should pursue through the use of the nude, at its most or at its less, naked, to become complete and self-sufficient.
Erotica, nudity or pornography are the discourse of our sexuality and human condition. For this reason, to represent more facets of the psychological, physical and fleshly aspects of the body is as crucial to our culture as to our own fulfillment.
