'.4.VII. Functions of Logic - or, Functions to the performance or exercise of which, in relation to other arts and sciences, Logic gives direction and assistance.

By the word functions, if it be not considered as an exact synonym to the word operations, the mind will naturally be led to the idea of the sort of person expressed by its conjugate functionary - a functionary, considered in the character of a person, by whom in virtue of some special engagement taken or task undertaken by him, these several operations will, in the prosecution of some special design or other, in relation to this or that subject or subjectmatter, have come to be performed.

1. Learning - 2. Using, practising, employing, or applying - 3. Teaching - 4. Improving - viz. the acquirement in question - the art - the science - to one or other of these heads may be referred whatsoever courses of operations, considered as having for their ideal subjectmatter any branch of art or science, have been in use to be considered as capable by the name of functions any or all of them capable of being at the same or different times exercised by the same hand, but all of them capable of being considered as the work of so many different hands, or if of the same hand, at different points of time.

Of the course or mode of action for the designation of which the word operation was employed, some there may be that may be found preeminently or even exclusively applicable to this or that branch of art or science, inapplicable to this or that other.

Of the more extensive courses of action for the designation of which the word function is here employed, there is not one that is not alike applicable without exception or distinction to every branch of art and science.
