The nature of sexuality, understood as an aspect of the evolution of consciousness in general and the descent of the potency in particular, is a subject of some prominence in Unancestral Voice.

The work of the British novelist and poet D. H. Lawrence, one of the most controversial commentators on sexuality in this century, occasions several of Barfield's reflections.

Lawrence [Barfield has his mouthpiece Burgeon say] had had the penetration to see below the symptom. Twentieth century man was dimly, gropingly, feebly finding the potency where it actually was--within; within the physical frame where a man was separate and alone. But Lawrence had also divined the truth that, although it was within him, it did not belong to him. It was his surviving real link with the cosmos, out of which even his separateness had been born. It was his present being. (31)

Contemporary sexuality is thus not universal or timeless but a facet of our interiorization. Though "desperately wrong" in most of their philosophy of sexuality (especially the conviction that "enthusiastic copulation is pretty well all that is required to set [things] right" [UV 33]), Lawrence and his followers, Barfield firmly acknowledged,

were right, a thousand times, in their insistence that the everlasting "sex" with which the twentieth century is obsessed to the verge of demonic possession is infinitely more than the surface thrill as which it was mostly accepted, infinitely more also than a basis of intimate companionship between persons of opposite sex; infinitely more than the means to the procreation of children. They were right in divining through it a mightiness that had been shackled and should now be set free. (32-33)
