Although I do not agree with the author's prophetic views and his numerous satirical, religious notions; however, his illustration on the futility of the doctrine of the trinity is quite apt.
Here it is:
"There was a fantastic episode of Star Trek Next Generation (Season 6, Episode 11, Chain of command II), where Captain Jean Luc Picard was captured by the Cardassians and tortured for information by Gul Madred.
The procedure that the Cardassians employed was very simple.
They shone 4 lights at him and asked him: How many lights do you see? He said: Four. Gul Madred falsely represented that there were 5. The aliens would then give him pain and torture every time Picard said that there were 4 lights, and then ask him the question again.
To cut a long story short he never broke and continued to represent throughout the entire process that there were precisely four lights.
When he was rescued by his ship mates they all congratulated him on his unbreakable will power and strength and told him what a great captain he was, and what a wonderful example to the crew he had set. But Jean Luc confided to one of the crew just how much he desperately wanted to convince himself that there were 5 lamps. He said that he was minutes away from cracking and agreeing that 4 was 5. Of course once he agrees to that, he has lost his objectivity and it is game over. You can get anything you want from him.
The plot is an adaption of George Orwell's 1984 where O'Brien tortures Winston by holding up 4 fingers in front of his face and then insisting that there are 5.
The Trinity Doctrine that began with the Catholic church and spread to many other churches is just that process. The trinity is the abolition of the number 3. The victim is asked to accept that 1 is 3 and 3 is 1."
