- n. The science of the distinction of true from false reasoning, with whatever is naturally treated in connection therewith. See the phrases below. The definition of logic has been much disputed, and many definitions of the word have been given. There was much discussion in ancient and medieval times of the questions whether logic was a mode of knowing, or an instrument of science, or an art, or a practical science, or a speculative science. There was also a great diversity of opinion as to the subject-matter of logic, some holding that it had to do with words, others that it treated of the ens rationis, or that which has its existence in thought, and still others that it related to argumentations or some instrument of knowing. In modern times, especially since Kant, the real divergence of conception has been very much greater, one party holding that the main business of logic consists in developing the true theory of the process of cognition, and a second that its chief work is to separate inferences into classes distinguished by their form, while a third maintains that the form and the matter of thought have to be evolved together.
