Heidegger, Martin. Logic: The Question of Truth.
Heidegger notes that genuinely philosophical logic has had only two masters: Aristotle, "the Father of Logic," and Hegel, his "only-begotten and co-equal son." He adds: "In order to advance philosophically, [logic] needs a new lineage. When that will come about, no one knows. We of today are certainly not up to it." Not hoping to further the brief history of logic, Heidegger's more modest goal was to revive the question: "What is truth?", first by examining Husserl's critique of psychologism in the Logical Investigations and then by showing "the need to take the question of the essence of truth back to Aristotle." Preparation for thinking further about logic leads Heidegger to a phenomenological analysis of human be-ing as existence (Dasein). The fundamental mode of the being (Sein) of existence is shown to be care (Sorge) and the "basic determination of being itself' is revealed as time or ur-temporality (Temporalitat). These words and Existenz are, of course, the basic vocabulary of Sein und Zeit, which Heidegger went on to complete soon after giving the last lecture of the course.
Heidegger's lectures focus on the Greek notion of [TEXT NOT REPRODUCIBLE IN ASCII] in its various senses, but especially as speech, where "we understand speech as the revealing of something by speaking about it, and as a thinking that determines and orders it. Language, speaking, thinking: they coincide as the human way of being." His achievement is to show that the hidden theme of propositional (scholastic) logic is time, but not as Aristotle had understood it. We require a new concept of time, which Heidegger had offered a year earlier, in the summer of 1924, to the Theological Society at Marbug. A retrieval of Kant's understanding of time is the theme of much of Part II of Heidegger's course. While Kant seems to have been on the way to a breakthrough and a new lineage for logic, he too is shown to have merely taken over via medieval philosophy (as mediated by Leibniz) Aristotle's concept of time. Hegel and Bergson are also shown to be beholden to Aristotle.
Thomas Sheehan has here set the standard of excellence against which all future translations of Heidegger into English must be measured. At long last, the English-speaking reader is spared the unnecessary mystification of the word Dasein. Only Existenz is left untranslated. In his lectures on Holderlin's poem "Der Ister," read in the summer of 1942, Heidegger said to his students: "Tell me what you think about translating and I will tell you who you are." Professor Sheehan shows us who he is by making accessible the way of thinking of the Heidegger of Sein und Zeit.--Miles Groth, Wagner College.
