I largely agree, but I wonder about this:
This doesn't seem to correspond to how Heraclitus understood logos:Most cultures believed that there were two recognized ways of arriving at truth. The Greeks called them mythos and logos. Both were essential and neither was superior to the other; they were not in conflict but complementary, each with its own sphere of competence. Logos ("reason") was the pragmatic mode of thought that enabled us to function effectively in the world and had, therefore, to correspond accurately to external reality. But it could not assuage human grief or find ultimate meaning in life's struggle. For that people turned to mythos ...
For Heraclitus, evidently, the Logos was much more like the Tao.
This Logos holds always but humans always prove unable to understand it, both before hearing it and when they have first heard it. For though all things come to be in accordance with this Logos, humans are like the inexperienced when they experience such words and deeds as I set out, distinguishing each in accordance with its nature and saying how it is. But other people fail to notice what they do when awake, just as they forget what they do while asleep.
