It appears Sigmund Freud had a strong emotional attachment to his sexual theory, he cleaved to it quite strongly, and ultimately this attachment prevented him from finding the absolute truth because he dismissed deeper truths that could possibly undermine his own ideas.Jung speaking of Freud:
“I can still recall vividly how Freud said to me “My dear Jung, promise me never to abandon the sexual theory. That is the most essential thing of all. You see, we must make a dogma of it, an unshakable bulwark.â€
He said that to me with great emotion, in the tone of a father saying, “And promise me this one thing, my dear son: that you will go to church every Sunday.†In some astonishment I asked him, “A bulwark—against what?†To which he replied, “Against the black tide of mud†–and he hesitated for a moment, then added – “of occultism.†… What Freud seems to mean by “occultism†was virtually everything that philosophy and religion, including the rising contemporary science of parapsychology had learned about the psyche.
And about the earlier 1907 meeting, Jung reveals:
Above all, Freud’s attitude toward the spirit seemed to me highly questionable. Whenever, in a person or in a work of art, an expression of spirituality (in the intellectual, not the supernatural sense) came to light, he suspected it, and insinuated that it was repressed sexuality. Anything that could not be directly interpreted as sexuality he referred to as “psychosexuality.†I protested that this hypothesis, carried to its logical conclusion, would lead to an annihilating judgment upon culture. Culture would then appear as a mere farce, the morbid consequence of repressed sexuality. “Yes.†He assented. “so it is, and that is just a curse of fate against which we are powerless to contend.â€â€¦ There was no mistaking the fact that Freud was emotionally involved in his sexual theory to an extraordinary degree. When he spoke of it, his tone became urgent, almost anxious…. A strange, deeply moved expression came over his face…â€
Ernest Becker:
“A base cause for his own lifelong twisting was that he would never cleanly leave the sexual dogma, never clearly see or admit that the terror of death was the basic repressionâ€
“The fiction of death as an ‘instinct’ allowed Freud to keep the terror of death outside his formulations as the primary human problem of ego masteryâ€
“As Rank says: Freud disposed of the ‘death problem’ and made it into a ‘death instinct’….â€even when he finally stumbled upon the inescapable death problem, he sought to give a new meaning to that also in harmony with the wish, since he spoke of death instinct instead of death fear, the fear itself he had meantime disposed of elsewhere, where it was not so threateningâ€
The yearning for the self-preservation of his sexual theories seems closely related to the nagging fear of his own mortality, which he wasn’t able to resolve.
