Historical (Dasein) was unable to hang onto the delicate and fragile pre-Socratic notion of truth. It was a house bound to collapse.Continued.
However, with this falsification of the true Logos as one with being as Physis, the science of logic was rendered possible, and came into being. It was Plato and Aristotle who were the true founders of logic; and as will be seen in the following section, it was with the help of logic that western philosophy has so successfully arrived to nihilism. Of course, any resemblance to the original notions of truth and being in the pre-Socratics and their intimate relation to one another, any inkling of being as the unconcealed (Seins als Unverborgenheit), is completely lost through the falsified Logos of logic. For the source of the essence of a thing is in being and in truth, a fact which logic cannot comprehend.
And even worse than all this, logic has come to determine our view of language, language which is itself the very dwelling place of being. All this begins when the being of things appears as Idea, or becomes simply the object of some science or other.
For when the Logos which anticipates the falsified Logos of logic comes to be the court of justice (Gerichtshof) over being, we have the beginning of the end of the great beginning of Greek philosophy. In Heidegger's view this end of the Anfang and the beginning of the Beginn of Greek philosophy comes to be in Plato and Aristotle. For as he has noted, in Plato it is Idea which becomes the predominant name for being.
