'.3.VIII Uses of Logic or, Uses to which Logic is applicable.

VI. Uses of Logic: uses capable of being made of this branch of art and science: art: uses to which it is capable of being put.

In this case as on[?] any other - in the instance of this art as in regard to every other, an use is either a modification of the universal end, i.e. well-being: or a subordinate and subservient end, i.e. a means, capable of being employed towards the attainment of that same universal end.

Be the thing, be the object what it may, if it neither performs nor contributes to the performance of service in either of these shapes, it is of no use - use, real use, it has none.

 Refer here to tit. Ethics, or take from thence some of the most general matter and insert it here.

If it has any use belonging to it that can with propriety and intelligibility be termed use, it must be either by a direct way to encrease the aggregate mass of pleasure or applying defalcation to the aggregate mass of pain: or else by contributing or tending to contribute in some way or other less immediate to the production of one or other or both of those ever desirable and ultimately only desirable effects.

Of the field of exercise of this art a sketch has been already given above: the aggregate of its uses is coextensive with that field.
