Preface to the Phenomenology of Mind
Φ 40. Dogmatism as a way of thinking, whether in ordinary knowledge or in the study of philosophy, is nothing else but the view that truth consists in a proposition, which is a fixed and final result, or again which is directly known. To questions like, “When was Caesar born?”. “How many feet make a furlong?”, etc., a straight answer ought to be given; just as it is absolutely true that the square of the hypotenuse is equal to the sum of the squares of the other two sides of a right-angled triangle. But the nature of a so-called truth of that sort is different from the nature of philosophical truth.
I think Hegel would agree that philosophical truth is a manner of dealing with the Coherence of the underlying philosophy.
