The disrepute into which Formal Logic has fallen is entirely unjustified; and its neglect is the root cause of nearly all those disquieting symptoms which we have noted in the modern intellectual constitution. Logic has been discredited, partly because we have come to suppose that we are conditioned almost entirely by the intuitive and the unconscious. There is no time to argue whether this is true; I will simply observe that to neglect the proper training of the reason is the best possible way to make it true.
Another cause for the disfavor into which Logic has fallen is the belief that it is entirely based upon universal assumptions that are either unprovable or tautological. This is not true. Not all universal propositions are of this kind. But even if they were, it would make no difference, since every syllogism whose major premise is in the form “All A is B” can be recast in hypothetical form. Logic is the art of arguing correctly: “If A, then B.” The method is not invalidated by the hypothetical nature of A. Indeed, the practical utility of Formal Logic today lies not so much in the establishment of positive conclusions as in the prompt detection and exposure of invalid inference.
Let us now quickly review our material and see how it is to be related to Dialectic. On the Language side, we shall now have our vocabulary and morphology at our fingertips; henceforward we can concentrate on syntax and analysis (i.e., the logical construction of speech) and the history of language (i.e., how we came to arrange our speech as we do in order to convey our thoughts).
Our Reading will proceed from narrative and lyric to essays, argument and criticism, and the pupil will learn to try his own hand at writing this kind of thing. Many lessons–on whatever subject–will take the form of debates; and the place of individual or choral recitation will be taken by dramatic performances, with special attention to plays in which an argument is stated in dramatic form.
