Indulge me, allow me take a swing at a needed word that has been all but excommunicated from the English language among those called civilized company, enlightened company, politically correct company... the various forms of the word-symbol perversion. I'm going to be trying for a functional definition, as all such definitions must be to avoid the perils and pitfalls of circular social reasoning, an empirical definition that may be applied to the full spectrum of the human condition.
I'm going to begin by saying perversion is any empowered* structure of thought that in objective fact does more to compromise the lives of those within a common sphere of empathy than it compromises the life hosting the structure. Perversion is that which ultimately reduces all who come in contact with it in their ability to meet any of the three foundation requirements of all life (sustenance, security, procreation). When examined exclusively at the individual level perversion commonly seems fairly benign to the life hosting the thought, perhaps even beneficial in some ways, and yet when the field of view is expanded to consider the lives in immediate contact in the same frame of reference it is easily seen as bane and detriment to the lives around that life.
*(empowered: translated from the inner first reality by way of word or deed into the public second reality)
By the definition offered above perversion resolves as an erosive force rather than an explosive one, no sharp impact but rather a slow grinding whose effect is easily overlooked or mistakenly assigned to some other cause. Entertaining such a definition for even a few moments of thought makes it quite obvious there are more than a few things that are considered perversions in greater or lesser degree that really do not satisfy such a definition, and equally there are an even greater number things that meet such a definition that are not commonly called perverted. Such a definition actually does a pretty decent job of shuffling the deck of society, very little remains where it was.
There is however one facet of this definition that makes it possible to begin sorting the confusion with even more precision than before, that being the implications involved with the concept of empowerment. If it is accepted that perversion primarily works its' ill through the lives around the one hosting the perverted form of thought it then follows that the mechanisms transmitting perversion are available for inspection by those willing to risk exposing themselves to the toxin. So, for a grab and go guestimate on the amount of perversion actually active in our world set the number of perversions equal to the number of pornographies* in our world: sex porn, pain porn, pistol porn, power porn, political porn... and on and on and on etcetera ad nauseam. The list is long and heartbreaking. Just how much perversion is actually impacting on our world?
*(pornography: any offering on any media selling the fantasy some single focus can create the life desired rather than the solid fact that any all consuming single focus simply reflects the limits of the life already in existence)
The simple fact of the matter is that perversion of one sort or another permeates the full spectrum of the human condition. These days there is a movement defending those who host perversion as being necessary components, some psychological mutagen driving social evolution, a foundation element of the human condition. Perhaps. But I'm not prepared to subscribe to such a belief. I'm more of a mind to believe society has degraded to the point of saying to itself since no one has been able to fix the problems they must indeed be part of the foundations of humanity.
