A Short History of Philosophy





Theory. θεωρία. A beholding, from θεωρέε, to look at, to behold. Hence theory comes to mean mental contemplation as distinguished from practice, and knowledge is divided into theoretical and practical, according as its end is merely speculative or to be carried out in action.


These, however, cannot always or generally be kept separate. Mere theoretic knowledge, knowledge that furnishes no guide to any sort of action, is a rarer possession than might at first sight be imagined, if indeed such a possession exists, while no practical art can be exercised without some knowledge of means and of ends, of causes and effects, which will come under the head of theory.

The theoretical and the practical life are, the one that of the contemplative student, the other that of the man of business, of politics, and of affairs.

These are the true meanings of the words theory and theoretic. The making the former a synonym of conjecture is an abusive application of it, though it is one largely made. Even so distinguished a man as Reid is guilty of it.(1)
