Incontrast...
Incontrast, there have been others, who chose to equate love with a sort of libido, or any persistent metabolic intensity of the sexual instinct. Evidently, they tended to assume that love is rather incapable of sublimation even in Divine terms. They treat love as if it has neither any spiritual origin, nor it is (or ought to be) humane in quality, nor it can be humanitarian in purpose.
Those who treat love as both Divine and human differentiate between the animal-like manifestation and the humane accomplishment of love. The others make no such distinction, so that love and lust become synonymous. Today, a third category of thinkers has become evident. They believe that all kinds of love are sexually prompted, but gradually the carnal motivation assumes a spiritual or contemplative aspect under specific conditions.
To them, love is primarily sexual, with only occasional platonic manifestations. However, this dual or two-fold quality of love is affirmed by them only in terms of its expression, objective and effects. There is no duality in so far as the origin and causation of love are concerned.
With regard to the last category of thinkers mentioned above, it is not a matter of surprise that they believe in a material basis of human spirituality They see no unsurmountable difficulty in the mutual transformation of the material and spiritual aspects of human behaviour. In fact, one of them claims that every spiritual affair has a natural basis and every natural thing has a spiritual extension.
[^1] Be that as it may, we need not discuss the above in any great psychological and philosophical depth. We can thus avoid going into the pros and cons of the many ancient and current interpretations of any basis of love. For the time being, it should be enough to suggest that love, in effect, can bring about creativity of the human intellect and spirit, as well as induce artistic and cultural refinements of sociological importance.
The above suggestion is valid, irrespective of whether or not love originates in the sexual instinct, and then becomes capable of expressing itself in physical and also spiritual terms, in an interchangeable manner. Any sublime effect of love is far different from its alleged instinctiveness, or simple animal-like concupiscenee, which seeks no more than its physiological gratification. Love does evidence itself as lust in some circumstances.
