Century Dictionary (33)

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. Logike hath eke in his degree Betwene the trouth and the falshede The pleyne wordes for to shede. Gower, Conf. Amant., vii. He that knoweth reason to be in man, and the same geven by the greate might of God, must nedes confesse the Logique also is in man, and that onely by God. For there is none other difference betwixt the one and thother but that Logique is a Greke worde and Reason is an Englishe woorde. … Logique is an arte to reason probably on bothe partes of al matiers that be putte foorth, so ferre as the nature of every thing can beare. Sir T. Wilson, Rule of Reason (1552).
[Dialectic and organon are generally synonyms of logic, though they have been variously distinguished at different times.]
Reasoning, or power of reasoning; ratiocination; argumentation; used absolutely, reason; sound sense. Ignorance in stilts, His cap well lined with logic not his own, With parrot tongue perform'd the scholar's part. Cowper, Task, ii. 737.
