We have already shewn, under the head NAMING, when explaining the purpose to which Predication is subservient, that all Predication may be strictly considered as of one kind, the application to the same thing of another name of greater extent; in other words, that Predication by what Logicians call the Difference, Property, or Accident of a thing, may be reduced to Predication by the Genus or Species; but as there is a seeming difference in these latter cases, a short illustration of them will probably be useful. Thus, suppose I say, "Man is rational," and that I choose to expound it, without the aid of the word animal, understood; what is there in the case? The word "man," marks a certain cluster of ideas. "Rational" marks a portion of that cluster. In the {391} cluster marked "man," the cluster marked "rational" is included. To recognise this, is also called believing the proposition. But to have one cluster of ideas, and know what it is; then another, and know what it is, is merely to have the two clusters. To have a second cluster, part of a first, and to know that it is a part of the first, is the same thing. The peculiar property of that class of words to which "Rational" belongs, must here be recollected. They are the _connotative_ class. Beside marking some thing peculiarly, they mark something else in conjunction; and this last, they are said to _connote_. Thus the word "rational," beside the part of the cluster, man, which it peculiarly marks, connotes, or marks in conjunction with it, the part included under the word animal It will be easy to apply the same explanation to all other cases. I say, the rose is red. Red is a connotative term, distinctively marking the idea of red. The idea of red is part of the cluster I mark by the word rose. Take a more obscure expression; Fire burns. It is very obvious, that in the cluster of ideas I mark by the word fire, the idea of burning is included. To have the idea, "fire," therefore, and the idea "burning," called up by the names standing in predication, is to believe the proposition. The Predications, "Virtue is lovely," "Vice is hateful," and the like, all admit of a similar exposition. In the cluster "virtue," the idea of loveliness is included; in the cluster "vice," that of hatefulness is included. Such propositions, therefore, merely say, that what is a part of a thing, is a part of it. The {392} two words call up the two ideas; and to have two ideas, one a part of another, and know that one is part of another, is not two things, but one and the same thing. To have the idea of rose, and the idea of red, and to know that red makes part of rose, is not two things, but one and the same thing.
