Adjectives of profit or disprofit, need prepositions to mark their connexion with the things benefited or hurt; as, hurtful to the crop; good for the health. These adjectives afford a good example of the manner in which generical adjectives are divided into numerous sub-species, without the inconvenience of new names, by the aid of the prepositions: thus, hurtful, which notes all kinds of hurtfulness, is made to note {206} its various species, in the following manner: hurtful to the health, hurtful to the eyes, hurtful to the stomach, hurtful to the crops, hurtful to the reputation: all different species of hurtfulness, which might be noted by adjectives severally appropriated to them. There is nothing particular to be remarked of the manner in which adjectives of plenty, or want, or those signifying an affection of the mind, are connected with the objects they connote, by prepositions; we shall, therefore, proceed to shew the manner in which verbs are connected with substantives, by their means. 3. All verbs are adjectives, either active or passive, put into a particular form, for the sake of a particular connotation. All actions, saving those which begin and end in the actor, have a reference to a patient, or something acted on; and the being acted on; the passion as it is called; has a reference to the actor. Action, therefore, and passion, are relative terms, standing in the order of cause and effect; agent and patient, are the names of the subjects of the action and the passion, the cause and the effect. Most actions are motions, or named by analogy to motions. In applying terms denoting motion, there is particular occasion for marking the two points of termination; the point at which it began, and the point at which it ended. This is effected by the name of the two places, and a preposition. The contrivance will be sufficiently illustrated by an obvious example: "John travelled from London to Dover:" "Travelled," the name of the motion; London, the point of commencement; Dover, the point of termination: from, a word denoting commencement, {207} connecting London with travelled; to, a word signifying completion, connecting the word Dover, with the word travelled. Some verbs, which imply motion, have their main, or only reference, to the point of its termination. Thus, he stopped at Dover: he struck him on the head: he stabbed him in the side. These prepositions, whatever their precise import, which we shall not now stop to inquire, mark, when thus applied to the name of the place at which the respective motions terminated, the connexion of the two names, that of the motion, and that of its point of termination.
