Pythagoras or Pre-socratics knew the truth (Sophers). Plato knew from his masters that there is an ultimate truth but did not know what exactly it was. He did not achieved it and hence he fantasized and wrote about it so much (Philosopher) but the reader will feel some inconsistency and hence remained unsatisfied. Aristotle, although far more superior and honest intellectually than Plato, did not believe many of the the "Plato's truth", and rejected it. Rival (Aristotle) of the rival (Plato) of Truth does not mean that he has found the Truth itself. 

Similarly, Jesus knew the truth. Organized Christianity knows that there is the ultimate truth but don't know exactly what it is, except, maybe at best, a handful of High Priests. Fascinated and fantasize by the truth of Jesus they created a religion much later, but there are some self contradictory issues and inconsistency. Seeing the inconsistency, the atheist started the doctrine that there is no truth unless I can see it and prove it. If I can not do it in my method nobody can and if somebody can then their method is not valid [not suspecting that there is a hidden flaw in this method]. Poor organized christianity and poor atheist. Both are misguided.

This is the cycle inside the cycle. The entire history is repeating the events that of small groups of people's lives. And a small group of people is repeating what one single person is doing to achieve knowledge. Whatever going on inside you, the whole world is doing that and vice versa. As above so below. Can you see it?
