In reality we have not advanced one step. I will not insist on the point that Instinct is a name for we know not what (to say that migratory birds find their way by instinct is only to say that we do not know how migratory birds find their way), for I think it is here being used in a fairly definite sense, to mean an unreflective or spontaneous impulse widely felt by the members of a given species. In what way does Instinct, thus conceived, help us to find "real" values? Is it maintained that we must obey instinct, that we cannot do otherwise? But if so, why are the Green Books and the like written? Why this stream of exhortation to drive us where we cannot help going? Why such praise for those who have submitted to the inevitable?

I can only conclude that I either misunderstand or that it is easy to confuse sexual orientation with romantic love, platonic love, brotherly fellowship, and other expressions of appropriate intimacy, all of which are genuine needs that would remain were sexual orientation to evolve.
