All is flux, nothing stays still - Plato

"[Dialogue between Solon and an Egyptian Priest]
In the Egyptian Delta, at the head of which the river Nile divides, there is a certain district which is called the district of Sais [...] To this city came Solon, and was received there with great honour; he asked the priests who were most skilful in such matters, about antiquity, and made the discovery that neither he nor any other Hellene knew anything worth mentioning about the times of old. On one occasion, wishing to draw them on to speak of antiquity, he began to tell about the most ancient things in our part of the world-about Phoroneus, who is called "the first man," and about Niobe; and after the Deluge, of the survival of Deucalion and Pyrrha; and he traced the genealogy of their descendants, and reckoning up the dates, tried to compute how many years ago the events of which he was speaking happened. Thereupon one of the priests, who was of a very great age, said: O Solon, Solon, you Hellenes are never anything but children, and there is not an old man among you. Solon in return asked him what he meant. I mean to say, he replied, that in mind you are all young; there is no old opinion handed down among you by ancient tradition, nor any science which is hoary with age."

And if the truth of all things that are is always in our soul, then the soul must be immortal, so you should take courage and whatever you do not happen to know, that is to remember, at present, you must endeavour to discover and recollect...I cannot swear to everything I have said in this argument – but one thing I am ready to fight for in word and deed, that we shall be better, braver and more active men if we believe it right to look for what we do not know, than if we think we cannot discover it and have no duty to seek it.

Writing is the geometry of the soul.
