Indeed, we may safely postulate that a large portion of what we call our individuality is a function of those chronic postures which our habits have hitherto established in our motor mechanism,—which postures ever thereafter determine what we shall do, say, and believe. 4. As deduced from Class D. Here the word “right” is used to signify “the hand which is normally the stronger,” whence, by association, it refers to a variety of related things, as hitherto indicated. We have previously noted that the concept “right” is a term we often use when the attainment of a purpose is under consideration, and here we again see the same motif displayed. Everybody knows that the “right” hand is important in the acquisition of skill of all sorts, and in getting in touch with the things we call “good.” Evidences of the paramount usefulness of the “right” hand to carry out overt actions are ubiquitous. Moreover, levers, pliers, and a hundred other tools are simply extensions of its functions and magnifications of its powers. What, then, are the action-patterns suggested by this use of our concept? The answer is extremely simple. The action-patterns we seek are the innumerable activities of the _right_ hand itself. For, as we have previously shown, even to think of the hand involves neuro-muscular activity in it. What the right hand _does_, is what the concept “right,” as applied to the hand, _means_. And if, for any reason, the “right” hand is incapacitated or missing, some other part of the body executes the appropriate gesture or manœuvre.
