Utility, n.
Etymology: [OE. utilite, F. utilité, L. utilitas, fr. utilis useful. See Utile.]
1. The quality or state of being useful; usefulness; production of good; profitableness to some valuable end; as, the utility of manure upon land; the utility of the sciences; the utility of medicines. The utility of the enterprises was, however, so great and obvious that all opposition proved useless. Macaulay.
2. (Polit. Econ.)
Adaptation to satisfy the desires or wants; intrinsic value. See Note under Value, 2. Value in use is utility, and nothing else, and in political economy should be called by that name and no other. F. A. Walker.
3. Happiness; the greatest good, or happiness, of the greatest number, -- the foundation of utilitarianism. J. S. Mill.
1 more senses
Syn. -- Usefulness; advantageous; benefit; profit; avail; service. -- Utility, Usefulness. Usefulness has an Anglo-Saxon prefix, utility is Latin; and hence the former is used chiefly of things in the concrete, while the latter is employed more in a general and abstract sense. Thus, we speak of the utility of an invention, and the usefulness of the thing invented; of the utility of an institution, and the usefulness of an individual. So beauty and utility (not usefulness) are brought into comparison. Still, the words are often used interchangeably.
Shades of meaning
Utility (L. utilis, useful) signifies primarily the quality of being useful, but is somewhat more abstract and philosophical than usefulness or use, and is often employed to denote adaptation to produce a valuable result, while usefulness denotes the actual production of such result. We contrast beauty and utility. We say of an invention, its utility is questionable, or, on the other hand, its usefulness has been proved by ample trial, or I have found it of use; still, utility and usefulness are frequently interchanged. Expediency (L. ex, out, and pes, foot; literally, the getting the foot out) refers primarily to escape from or avoidance of some difficulty or trouble; either expediency or utility may be used to signify profit or advantage considered apart from right as the ground of moral obligation, or of actions that have a moral character, expediency denoting immediate advantage on a contracted view, and especially with reference to avoiding danger, difficulty, or loss, while utility may be so broadened as to cover all existence through all time, as in the utilitarian theory of morals. Policy is often used in a kindred sense, more positive than expediency but narrower than utility, as in the proverb, "Honesty is the best policy." Compare profit.
