In the earliest periods of civilization, translators have been the agents for propagating knowledge from nation to nation, and the value of their labours has been inestimable; but, in the present age, when so many different languages have become the depositories of the vast treasures of literature and science which have been accumulating for centuries, the utility of accurate translations has greatly increased, and it has become a more important object to attain perfection in the art.
The use of language is not confined to its being the medium through which we communicate our ideas to one another; it fulfils a no less important function as an instrument of thought; not being merely its vehicle, but giving it wings for flight. Metaphysicians are agreed that scarcely any of our intellectual operations could be carried on to any considerable extent, without the agency of words. None but those who are conversant with the philosophy of mental phenomena can be aware of the immense influence that is exercised by language in promoting the development of our ideas, in fixing them in the mind, and in detaining them for steady contemplation.
Into every process of reasoning, language enters as an essential element.
