I've always interpreted it to refer to an orientation towards looking at the world in terms of separation rather than unification. All is one, and perfect, but one can subjectively choose to look at it through the eyes of "perversity", or opposition to nature, and see and interpret it through the lens of separation.
So essentially it boils down to how we, in our illusory egoic separation, choose to relate to the rest of creation. Do we try to see how we are ultimately the same being, or do we try to see how we are different and separate from one another? Looking for reasons to see and feel separation, and finding satisfaction in that, would be "examining the perversities of nature". A perversion is a kind of reversal, so "perversities of nature" would connote a reversal of that which is natural (i.e. oneness). Oneness is real, and separation is an unreal, interpretation of the real.
It is also important to note, at our level of existence, our orientation, even as STO beings, which is towards oneness is also an unreal interpretation. We are still looking at reality through a lens, or separated perspective of consciousness, and thus both STS and STO perspectives are distorted with regard to actual reality. Both polarities as they gain power and awareness become more acutely conscious of the line in the sand between truth/falsity, but they both wield this awareness in precisely opposite ways: to illuminate (accept/unify), or to deceive (control/separate).
