The absolute, irrelative particle primarily created by the Volition of God, must have been in a condition of positive _normality_, or rightfulness—for wrongfulness implies _relation_. Right is positive; wrong is negative—is merely the negation of right; as cold is the negation of heat—darkness of light. That a thing may be wrong, it is necessary that there be some other thing in _relation_ to which it _is_ wrong—some condition which it fails to satisfy; some law which it violates; some being whom it aggrieves. If there be no such being, law, or condition, in respect to which the thing is wrong—and, still more especially, if no beings, laws, or conditions exist at all—then the thing can_not_ be wrong and consequently must be _right_. Any deviation from normality involves a tendency to return into it. A difference from the normal—from the right—from the just—can be understood as effected only by the overcoming a difficulty; and if the force which overcomes the difficulty be not infinitely continued, the ineradicable tendency to return will at length be permitted to act for its own satisfaction. Upon withdrawal of the force, the tendency acts. This is the principle of rëaction as the inevitable consequence of finite action. Employing a phraseology of which the seeming affectation will be pardoned for its expressiveness, we may say that Rëaction is the return from the condition of _as it is and ought not to be_ into the condition of _as it was, originally, and therefore ought to be_:—and let me add here that the _absolute_ force of Rëaction would no doubt be always found in direct proportion with the reality—the truth—the absoluteness—of the _originality_—if ever it were possible to measure this latter:—and, consequently, the greatest of all conceivable reactions must be that produced by the tendency which we now discuss—the tendency to return into the _absolutely original_—into the _supremely_ primitive. Gravity, then, _must be the strongest of forces_—an idea reached _à priori_ and abundantly confirmed by induction. What use I make of the idea, will be seen in the sequel.
