The spectacle of so many and so various systems of philosophy suggests the necessity of defining more exactly the relation of Universal to Particular. When the universal is made a mere form and co-ordinated with the particular, as if it were on the same level, it sinks into a particular itself. Even common sense in every-day matters is above the absurdity of setting a universal beside the particulars. Would any one, who wished for fruit, reject cherries, pears, and grapes, on the ground that they were cherries, pears, or grapes, and not fruit? But when philosophy is in question, the excuse of many is that philosophies are so different, and none of them is the philosophy,—that each is only a philosophy. Such a plea is assumed to justify any amount of contempt for philosophy. And yet cherries too are fruit. Often, too, a system, of which the principle is the universal, is put on a level with another of which the principle is a particular, and with theories which deny the existence of philosophy altogether. Such systems are said to be only different views of philosophy. With equal justice, light and darkness might be styled different kinds of light.
14.] The same evolution of thought which is exhibited in the history of philosophy is presented in the System of Philosophy itself. Here, instead of surveying the process, as we do in history, from the outside, we see the movement of thought clearly defined in its native medium. The thought, which is genuine and self-supporting, must be intrinsically concrete; it must be an Idea; and when it is viewed in the whole of its universality, it is the Idea, or the Absolute. The science of this Idea must form a system. For the truth is concrete; that is, whilst it gives a bond and principle of unity, it also possesses an internal source of development. Truth, then, is only possible as a universe or totality of thought; and the freedom of the whole, as well as the necessity of the several sub-divisions, which it implies, are only possible when these are discriminated and defined.
Unless it is a system, a philosophy is not a scientific production. Unsystematic philosophising can only be expected to give expression to personal peculiarities of mind, and has no principle for the regulation of its contents. Apart from their interdependence and organic union, the truths of philosophy are valueless, and must then be treated as baseless hypotheses, or personal convictions. Yet many philosophical treatises confine themselves to such an exposition of the opinions and sentiments of the author.
The term system is often misunderstood. It does not denote a philosophy, the principle of which is narrow and to be distinguished from others. On the contrary, a genuine philosophy makes it a principle to include every particular principle.
15.] Each of the parts of philosophy is a philosophical whole, a circle rounded and complete in itself. In each of these parts, however, the philosophical Idea is found in a particular specificality or medium. The single circle, because it is a real totality, bursts through the limits imposed by its special medium, and gives rise to a wider circle. The whole of philosophy in this way resembles a circle of circles. The Idea appears in each single circle, but, at the same time, the whole Idea is constituted by the system of these peculiar phases, and each is a necessary member of the organisation.
16.] In the form of an Encyclopaedia, the science has no room for a detailed exposition of particulars, and must be limited to setting forth the commencement of the special sciences and the notions of cardinal importance in them.
How much of the particular parts is requisite to constitute a particular branch of knowledge is so far indeterminate, that the part, if it is to be something true, must be not an isolated member merely, but itself an organic whole. The entire field of philosophy therefore really forms a single science; but it may also be viewed as a total, composed of several particular sciences.
The encyclopaedia of philosophy must not be confounded with ordinary encyclopaedias. An ordinary encyclopaedia does not pretend to be more than an aggregation of sciences, regulated by no principle, and merely as experience offers them. Sometimes it even includes what merely bear the name of sciences, while they are nothing more than a collection of bits of information. In an aggregate like this, the several branches of knowledge owe their place in the encyclopaedia to extrinsic reasons, and their unity is therefore artificial: they are arranged, but we cannot say they form a system. For the same reason, especially as the materials to be combined also depend upon no one rule or principle, the arrangement is at best an experiment, and will always exhibit inequalities.
An encyclopaedia of philosophy excludes three kinds of partial science. I. It excludes mere aggregates of bits of information. Philology in its prima facie aspect belongs to this class. II. It rejects the quasi-sciences, which are founded on an act of arbitrary will alone, such as Heraldry. Sciences of this class are positive from beginning to end. III. In another class of sciences, also styled positive, but which have a rational basis and a rational beginning, philosophy claims that constituent as its own. The positive features remain the property of the sciences themselves.
The positive element in the last class of sciences is of different sorts. (I) Their commencement, though rational at bottom, yields to the influence of fortuitousness, when they have to bring their universal truth into contact with actual facts and the single phenomena of experience. In this region of chance and change, the adequate notion of science must yield its place to reasons or grounds of explanation. Thus, e.g. in the science of jurisprudence, or in the system of direct and indirect taxation, it is necessary to have certain points precisely and definitively settled which lie beyond the competence of the absolute lines laid down by the pure notion. A certain latitude of settlement accordingly is left: and each point may be determined in one way on one principle, in another way on another, and admits of no definitive certainty. Similarly the Idea of Nature, when parcelled out in detail, is dissipated into contingencies. Natural history, geography, and medicine stumble upon descriptions of existence, upon kinds and distinctions, which are not determined by reason, but by sport and adventitious incidents. Even history comes under the same category. The Idea is its essence and inner nature; but, as it appears, everything is under contingency and in the field of voluntary action. (II) These sciences are positive also in failing to recognise the finite nature of what they predicate, and to point out how these categories and their whole sphere pass into a higher. They assume their statements to possess an authority beyond appeal. Here the fault lies in the finitude of the form, as in the previous instance it lay in the matter. (III) In close sequel to this, sciences are positive in consequence of the inadequate grounds on which their conclusions rest: based as these are on detached and casual inference, upon feeling, faith, and authority, and, generally speaking, upon the deliverances of inward and outward perception. Under this head we must also class the philosophy which proposes to build upon anthropology,' facts of consciousness, inward sense, or outward experience. It may happen, however, that empirical is an epithet applicable only to the form of scientific exposition; whilst intuitive sagacity has arranged what are mere phenomena, according to the essential sequence of the notion. In such a case the contrasts between the varied and numerous phenomena brought together serve to eliminate the external and accidental circumstances of their conditions, and the universal thus comes clearly into view. Guided by such an intuition, experimental physics will present the rational science of Nature,—as history will present the science of human affairs and actions—in an external picture, which mirrors the philosophic notion.
17.] It may seem as if philosophy, in order to start on its course, had, like the rest of the sciences, to begin with a subjective presupposition. The sciences postulate their respective objects, such as space, number, or whatever it be; and it might be supposed that philosophy had also to postulate the existence of thought. But the two cases are not exactly parallel. It is by the free act of thought that it occupies a point of view, in which it is for its own self, and thus gives itself an object of its own production. Nor is this all. The very point of view, which originally is taken on its own evidence only, must in the course of the science be converted to a result,—the ultimate result in which philosophy returns into itself and reaches the point with which it began. In this manner philosophy exhibits the appearance of a circle which closes with itself, and has no beginning in the same way
