If we agree with Hegel's opinion that philosophy is "an era grasped by thought," then we have to admit that some philosophers managed to "grab" (to grasp) their epoch with thought, others - not their own. Someone - retrospectively - the previous one, and someone - the one that was not yet at the time of his life. The number of the latter in the first place should most likely include Heraclitus. It is about him that will be discussed in our extremely concise essay. To say about Heraclitus, that he, with his views, "has outstripped his time", means not to say practically anything about him. At least, substantial. For our misunderstanding of what was said by Heraclitus two and a half thousand years ago, we are still paying the price, including the most expensive thing we have, with millions of human lives. How we "manage" to do this - read in the book.
