It will soon be two Thousand years since one of the earliest Christians, the wise author of the Fourth Gospel, a man who according to tradition was one of the twelve disciples of Jesus of Nazareth, wrote his famous sentence :

Ἐν ἀρχῇ ἦν ὁ λόγος

At the beginning there was the Word

But as we know, half a millenium earlier, another sage, Heraclitus of Ephesus, was the first man ever to use the word λόγος to express a philosophical and theological concept. It is he who gave to the word λόγος a conceptual pregnancy and gravity which it never lost ever since.
