ction is, to be the name or sign of something or some
multitude of things, which are said to be called or denoted by the term.
Its connotative function is, to suggest certain qualities and
characteristics of the things denoted, so that it cannot be used
literally as the name of any other things; which qualities and
characteristics are said to be implied or connoted by the term. Thus
'sheep' is the name of certain animals, and its connotation prevents its
being used of any others. That which a term directly indicates, then,
is its _Denotation_; that sense or customary use of it which limits the
Denotation is its _Connotation_ (ch. iv.). Hamilton and others use
'Extension' in the sense of Denotation, and 'Intension' or
'Comprehension' in the sense of Connotation. Now, terms may be
classified, first according to what they stand for or denote; that is,
according to their _Denotation_. In this respect, the use of a term is
said to be either Concrete or Abstract.

A term is Concrete when it denotes a 'thing'; that is, any person,
object, fact, event, feeling or imagination, considered as capable of
having (or consisting of) qualities and a determinate existence. Thus
'cricket ball' denotes any object having a certain size, weight, shape,
colour, etc. (which are its qualities), and being at any given time in
some place and related to other objects--in the bowler's hands, on the
grass, in a shop window. Any 'feeling of heat' has a certain intensity,
is pleasurable or painful, occurs at a certain time, and affects some
part or the whole of some animal. An imagination, indeed (say, of a
fairy), cannot be said in the same sense to have locality; but it
depends on the thinking of some man who has locality, and is definitely
related to his other thoughts and feelings.

A term is Abstract, on the other hand, when it denotes a quality (or
qualities), considered by itself and without determinate existence in
time, place, or relation to other things. 'Size,' 'shape,' 'weight,'
'colour,' 'intensity,' 'pleasurableness,' are terms used to denote such
qualities, and are then abstract in their denotation. 'Weight' is not
something with a determinate existence at a given time; it exists not
merely in some particular place, but wherever there is a heavy thing;
and, as to relation, at the same moment it combines in iron with
solidity and in mercury with liquidity. In fact, a quality is a point of
agreement in a multitude of different things; a
