Definitions of Logic

Definitions of Logic

Most treatises on logic begin with a discursion on the difficulty of defining the subject. Nevertheless, a definition is felt to be necessary. Here is a short summary of Definitions of logic that logicians throughout history have attempted, arranged in approximate chronological order.

* The tool for distinguishing between the true and the false (Averroes).
* The science of reasoning, teaching the way of investigating unknown truth in connection with a thesis (Robert Kilwardby).
* The art whose function is to direct the reason lest it err in the manner of inferring or knowing (John Poinsot).
* The art of conducting reason well in knowing things (Antoine Arnauld).
* The right use of reason in the inquiry after truth (Isaac Watts).
* The Science, as well as the Art, of reasoning (Richard Whately).
* The science of the operations of the understanding which are subservient to the estimation of evidence (John Stuart Mill).
* The science of the laws of discursive thought (James McCosh).
* The science of the most general laws of truth (Gottlob Frege).
* The science which directs the operations of the mind in the attainment of truth (George Hayward Joyce).
* The branch of philosophy concerned with analysing the patterns of reasoning by which a conclusion is drawn from a set of premisses (Collins English Dictionary)
* The formal systematic study of the principles of valid inference and correct reasoning (Penguin Encyclopedia).
