143.] Such a concrete category as Actuality includes the characteristics aforesaid and their difference, and is therefore also the development of them, in such a way that, as it has them, they are at the same time plainly understood to be a show, to be assumed or imposed (§ 141).

(α) Viewed as an identity in general, Actuality is first of all Possibility—the reflection-into-self which, as in contrast with the concrete unity of the actual, is taken and made an abstract and unessential essentiality. Possibility is what is essential to reality, but in such a way that it is at the same time only a possibility.

It was probably the import of Possibility which induced Kant to regard it along with necessity and actuality as Modalities, 'since these categories do not in the least increase the notion as object, but only express its relation to the faculty of knowledge.' For Possibility is really the bare abstraction of reflection-into-self,—what was formerly called the Inward, only that it is now taken to mean the external inward, lifted out of reality and with the being of a mere supposition, and is thus, sure enough, supposed only as a bare modality, an abstraction which comes short, and, in more concrete terms, belongs only to subjective thought. It is otherwise with Actuality and Necessity. They are anything but a mere sort and mode for something else: in fact the very reverse of that. If they are supposed, it is as the concrete, not merely supposititious, but intrinsically complete.

As Possibility is, in the first instance, the mere form of identity-with-self (as compared with the concrete which is actual), the rule for it merely is that a thing must not be self-contradictory. Thus everything is possible; for an act of abstraction can give any content this form of identity. Everything however is as impossible as it is possible. In every content,—which is and must be concrete,—the speciality of its nature may be viewed as a specialised contrariety and in that way as a contradiction. Nothing therefore can be more meaningless than to speak of such possibility and impossibility. In philosophy, in particular, there should never be a word said of showing that 'It is possible,' or 'There is still another possibility,' or, to adopt another phraseology, 'It is conceivable.' The same consideration should warn the writer of history against employing a category which has now been explained to be on its own merits untrue: but the subtlety of the empty understanding finds its chief pleasure in the fantastic ingenuity of suggesting possibilities and lots of possibilities.

Our picture-thought is at first disposed to see in possibility the richer and more comprehensive, in actuality the poorer and narrower category. Everything, it is said, is possible, but everything which is possible is not on that account actual. In real truth, however, if we deal with them as thoughts, actuality is the more comprehensive, because it is the concrete thought which includes possibility as an abstract element. And that superiority is to some extent expressed in our ordinary mode of thought when we speak of the possible, in distinction from the actual, as only possible. Possibility is often said to consist in a thing's being thinkable. 'Think,' however, in this use of the word, only means to conceive any content under the form of an abstract identity. Now every content can be brought under this form, since nothing is required except to separate it from the relations in which it stands. Hence any content, however absurd and nonsensical, can be viewed as possible. It is possible that the moon might fall upon the earth to-night; for the moon is a body separate from the earth, and may as well fall down upon it as a stone thrown into the air does. It is possible that the Sultan may become Pope; for, being a man, he may be converted to the Christian faith, may become a Catholic priest, and so on. In language like this about possibilities, it is chiefly the law of the sufficient ground or reason which is manipulated in the style already explained. Everything, it is said, is possible, for which you can state some ground. The less education a man has, or, in other words, the less he knows of the specific connexions of the objects to which he directs his observations, the greater is his tendency to launch out into all sorts of empty possibilities. An instance of this habit in the political sphere is seen in the pot-house politician. In practical life too it is no uncommon thing to see ill-will and indolence slink behind the category of possibility, in order to escape definite obligations. To such conduct the same remarks apply as were made in connexion with the law of sufficient ground. Reasonable and practical men refuse to be imposed upon by the possible, for the simple ground that it is possible only. They stick to the actual (not meaning by that word merely whatever immediately is now and here). Many of the proverbs of common life express the same contempt for what is abstractly possible. 'A bird in the hand is worth two in the bush.'

After all there is as good reason for taking everything to be impossible, as to be possible: for every content (a content is always concrete) includes not only diverse but even opposite characteristics. Nothing is so impossible, for instance, as this, that I am: for 'I' is at the same time simple self-relation and, as undoubtedly, relation to something else. The same may be seen in every other fact in the natural or spiritual world. Matter, it may be said, is impossible: for it is the unity of attraction and repulsion. The same is true of life, law, freedom, and above all, of God Himself, as the true, i.e. the triune God,—a notion of God, which the abstract 'Enlightenment' of Understanding, in conformity with its canons, rejected on the allegation that it was contradictory in thought. Generally speaking, it is the empty understanding which haunts these empty forms: and the business of philosophy in the matter is to show how null and meaningless they are. Whether a thing is possible or impossible, depends altogether on the subject-matter: that is, on the sum total of the elements in actuality, which, as it opens itself out, discloses itself to be necessity.

144.] (ß) But the Actual in its distinction from possibility (which is reflection-into-self) is itself only the outward concrete, the unessential immediate. In other words, to such extent as the actual is primarily (§ 142) the simple merely immediate unity of Inward and Outward, it is obviously made an unessential outward, and thus at the same time (§ 140) it is merely inward, the abstraction of reflection-into-self. Hence it is itself characterised as a merely possible. When thus valued at the rate of a mere possibility, the actual is a Contingent or Accidental, and, conversely, possibility is mere Accident itself or Chance.

146.] Possibility and Contingency are the two factors of Actuality,—Inward and Outward, put as mere forms which constitute the externality of the actual. They have their reflection-into-self on the body of actual fact, or content, with its intrinsic definiteness which gives the essential ground of their characterisation. The finitude of the contingent and the possible lies, therefore, as we now see, in the distinction of the form-determination from the content: and, therefore, it depends on the content alone whether anything is contingent and possible.

As possibility is the mere inside of actuality, it is for that reason a mere outside actuality, in other words, Contingency. The contingent, roughly speaking, is what has the ground of its being not in itself but in somewhat else. Such is the aspect under which actuality first comes before consciousness, and which is often mistaken for actuality itself. But the contingent is only one side of the actual,—the side, namely, of reflection on somewhat else. It is the actual, in the signification of something merely possible. Accordingly we consider the contingent to be what may or may not be, what may be in one way or in another, whose being or not-being, and whose being on this wise or otherwise, depends not upon itself but on something else. To overcome this contingency is, roughly speaking, the problem of science on the one hand; as in the range of practice, on the other, the end of action is to rise above the contingency of the will, or above caprice. It has however often happened, most of all in modern times, that contingency has been unwarrantably elevated, and had a value attached to it, both in nature and the world of mind, to which it has no just claim. Frequently Nature—to take it first,—has been chiefly admired for the richness and variety of its structures. Apart, however, from what disclosure it contains of the Idea, this richness gratifies none of the higher interests of reason, and in its vast variety of structures, organic and inorganic, affords us only the spectacle of a contingency losing itself in vagueness. At any rate, the chequered scene presented by the several varieties of animals and plants, conditioned as it is by outward circumstances,—the complex changes in the figuration and grouping of clouds, and the like, ought not to be ranked higher than the equally casual fancies of the mind which surrenders itself to its own caprices. The wonderment with which such phenomena are welcomed is a most abstract frame of mind, from which one should advance to a closer insight into the inner harmony and uniformity of nature.
