Logic thus reformed will still be _formal_ Logic; it will study the true form or activity of thought, the concept, excluding individual and particular concepts. The old Logic is ill called formal; it would be better to call it _verbal_ or _formalistic._ Formal Logic will drive out formalistic Logic. To attain this object, it will not be necessary to have recourse, as some have done, to a real or material Logic, which is no longer a science of thought, but thought itself in action; not only a Logic, but the whole of Philosophy, in which Logic is also included. The science of thought (Logic) is that of the concept, as that of imagination (Æsthetic) is that of expression. The well-being of both sciences lies in exactly carrying out in every particular the distinction between the two domains. _Note to the Fourth Italian Edition._--The observations contained in this chapter on Logic, which are not all of them clear or accurate, should be clarified and corrected by means of the further treatment of the theme in the second volume of the _Philosophy of the Spirit,_ dedicated to Logic, where the distinction between logical and historical propositions is again examined and their synthetic unity demonstrated. VI THE THEORETIC ACTIVITY AND THE PRACTICAL ACTIVITY The intuitive and intellectual forms contain between them, as we have said, the whole theoretic domain of the spirit. But it is not possible to know them thoroughly, nor to criticize another series of erroneous æsthetic theories, without first establishing clearly the relations of the theoretic spirit with the _practical_ spirit. [Sidenote: _The will._] The practical form or activity is the _will._ We do not here employ this word in the sense of some philosophical systems, where the will is the foundation of the universe, the ground of things and the true reality. Nor do we employ it in the wide sense of other systems, which understand by will the energy of the spirit, spirit or activity in general, making of every act of the human spirit an act of will. Neither such metaphysical nor such metaphorical meaning is ours. For us, the will is, as generally understood, that activity of the spirit which differs from the merely theoretical contemplation of things, and is productive, not of knowledge, but of actions. Action is really action, in so far as it is voluntary. It is not necessary to remark that in the will to do, we include, in the scientific sense, also what is usually called not-doing: the will to resist, to reject, the will of a Prometheus, which also is action. [Sidenote: _The will as an ulterior stage in respect to knowledge._]
