From the examples it will be seen that a general name logically is not necessarily a single word. Any word or combination of words that serves a certain function is technically a general name. The different ways of making in common speech the equivalent of a general name logically are for the grammarian to consider. In the definition of a general name attention is called to two distinct considerations, the individual objects to each of which the name is applicable, and the points of resemblance among them, in virtue of which they have a common name. For those distinctions there are technical terms. CLASS is the technical term for the objects, different yet agreeing, to each of which a general name may be applied. The points of resemblance are called the common ATTRIBUTES of the class. A class may be constituted on one attribute or on several. _Ratepayer_, _woman ratepayer_, _unmarried woman ratepayer_; _soldier_, _British soldier_, _British soldier on foreign service_. But every individual to which the general name can be applied must possess the common attribute or attributes. These common attributes are also called the NOTION of the class, inasmuch as it is these that the mind notes or should note when the general name is applied. CONCEPT is a synonym perhaps in more common use than notion; the rationale of this term (derived from _con_ and _capere_, to take or grasp together) being that it is by means of the points of resemblance that the individuals are grasped or held together by the mind. These common points are the one in the many, the same amidst the different, the identity signified by the common name. The name of an attribute as thought of by itself without reference to any individual or class possessing it, is called an ABSTRACT name. By contradistinction, the name of an individual or a class is CONCRETE. Technical terms are wanted also to express the relation of the individuals and the attributes to the general name. The individuals jointly are spoken of as the DENOTATION, or EXTENSION or SCOPE of the name; the common attributes as its CONNOTATION, INTENSION, COMPREHENSION, or GROUND. The whole denotation, etc., is the class; the whole connotation, etc., is the concept.[1] The limits of a "class" in Logic are fixed by the common attributes. Any individual object that possesses these is a member. The statement of them is the DEFINITION. To predicate a general name of any object, as, "This is a cat," "This is a very sad affair," is to refer that object to a class, which is equivalent to saying that it has certain features of resemblance with other objects, that it reminds us of them by its likeness to them. Thus to say that the predicate of every proposition is a general name, expressed or implied, is the same as to say that every predication may be taken as a reference to a class.
