science. The object of philosophy is the Idea: and the Idea is not so impotent as merely to have a right or an obligation to exist without actually existing. The object of philosophy is an actuality of which those objects, social regulations and conditions, are only the superficial outside.
7.] Thus reflection—thinking things over—in a general way involves the principle (which also means the beginning) of philosophy. And when the reflective spirit arose again in its independence in modern times, after the epoch of the Lutheran Reformation, it did not, as in its beginnings among the Greeks, stand merely aloof, in a world of its own, but at once turned its energies also upon the apparently illimitable material of the phenomenal world. In this way the name philosophy came to be applied to all those branches of knowledge, which are engaged in ascertaining the standard and Universal in the ocean of empirical individualities, as well as in ascertaining the Necessary element, or Laws, to be found in the apparent disorder of the endless masses of the fortuitous. It thus appears that modern philosophy derives its materials from our own personal observations and perceptions of the external and internal world, from nature as well as from the mind and heart of man, when both stand in the immediate presence of the observer.
This principle of Experience carries with it the unspeakably important condition that, in order to accept and believe any fact, we must be in contact with it; or, in more exact terms, that we must find the fact united and combined with the certainty of our own selves. We must be in touch with our subject-matter, whether it be by means of our external senses, or, else, by our profounder mind and our intimate self-consciousness.—This principle is the same as that which has in the present day been termed faith, immediate knowledge, the revelation in the outward world, and, above all, in our own heart.
Those sciences, which thus got the name of philosophy, we call empirical sciences, for the reason that they take their departure from experience. Still the essential results which they aim at and provide, are laws, general propositions, a theory—the thoughts of what is found existing. On this ground the Newtonian physics was called Natural Philosophy. Hugo Grotius, again, by putting together and comparing the behaviour of states towards each other as recorded in history, succeeded, with the help of the ordinary methods of general reasoning, in laying down certain general principles, and establishing a theory which may be termed the Philosophy of International Law. In England this is still the usual signification of the term philosophy. Newton continues to be celebrated as the greatest of philosophers: and the name goes down as far as the price-lists of instrument-makers. All instruments, such as the thermometer and barometer, which do not come under the special head of magnetic or electric apparatus, are styled philosophical instruments1. Surely thought, and not a mere combination of wood, iron, &c. ought to be called the instrument of philosophy! The recent science of Political Economy in particular, which in Germany is known as Rational Economy of the State, or intelligent national economy, has in England especially appropriated the name of philosophy.2
8.] In its own field this empirical knowledge may at first give satisfaction; but in two ways it is seen to come short. In the first place there is another circle of objects which it does not embrace. These are Freedom, Spirit, and God. They belong to a different sphere, not because it can be said that they have nothing to do with experience; for though they are certainly not experiences of the senses, it is quite an identical proposition to say that whatever is in consciousness is experienced. The real ground for assigning them to another field of cognition is that in their scope and content these objects evidently show themselves as infinite.
There is an old phrase often wrongly attributed to Aristotle, and supposed to express the general tenor of his philosophy. 'Nihil est in intellectu quod non fuerit in sensu': there is nothing in thought which has not been in sense and experience. If speculative philosophy refused to admit this maxim, it can only have done so from a misunderstanding. It will, however, on the converse side no less assert: 'Nihil est in sensu quod non fuerit in intellectu.' And this may be taken in two senses. In the general sense it means that νοῦς or spirit (the more profound idea of νοῦς in modern thought) is the cause of the world. In its special meaning (see § 2) it asserts that the sentiment of right, morals, and religion is a sentiment (and in that way an experience) of such scope and such character that it can spring from and rest upon thought alone.
9.] But in the second place in point of form the subjective reason desires a further satisfaction than empirical knowledge gives; and this form, is, in the widest sense of the term, Necessity (§ 1). The method of empirical science exhibits two defects. The first is that the Universal or general principle contained in it, the genus, or kind, &c., is, on its own account, indeterminate and vague, and therefore not on its own account connected with the Particulars or the details. Either is external and accidental to the other; and it is the same with the particular facts which are brought into union: each is external and accidental to the others. The second defect is that the beginnings are in every case data and postulates, neither accounted for nor deduced. In both these points the form of necessity fails to get its due. Hence reflection, whenever it sets itself to remedy these defects, becomes speculative thinking, the thinking proper to philosophy. As a species of reflection, therefore, which, though it has a certain community of nature with the reflection already mentioned, is nevertheless different from it, philosophic thought thus possesses, in addition to the common forms, some forms of its own, of which the Notion may be taken as the type.
The relation of speculative science to the other sciences may be stated in the following terms. It does not in the least neglect the empirical facts contained in the several sciences, but recognises and adopts them: it appreciates and applies towards its own structure the universal element in these sciences, their laws and classifications: but besides all this, into the categories of science it introduces, and gives currency to, other categories. The difference, looked at in this way, is only a change of categories. Speculative Logic contains all previous Logic and Metaphysics: it preserves the same forms of thought, the same laws and objects,—while at the same time remodelling and expanding them with wider categories.
From notion in the speculative sense we should distinguish what is ordinarily called a notion. The phrase, that no notion can ever comprehend the Infinite, a phrase which has been repeated over and over again till it has grown axiomatic, is based upon this narrow estimate of what is meant by notions.
10.] This thought, which is proposed as the instrument of philosophic knowledge, itself calls for further explanation. We must understand in what way it possesses necessity or cogency: and when it claims to be equal to the task of apprehending the absolute objects (God, Spirit, Freedom), that claim must be substantiated. Such an explanation, however, is itself a lesson in philosophy, and properly falls within the scope of the science itself. A preliminary attempt to make matters plain would only be unphilosophical, and consist of a tissue of assumptions, assertions, and inferential pros and cons, i.e. of dogmatism without cogency, as against which there would be an equal right of counter-dogmatism.
A main line of argument in the Critical Philosophy bids us pause before proceeding to inquire into God or into the true being of things, and tells us first of all to examine the faculty of cognition and see whether it is equal to such an effort. We ought, says Kant, to become acquainted with the instrument, before we undertake the work for which it is to be employed; for if the instrument be insufficient, all our trouble will be spent in vain. The plausibility of this suggestion has won for it general assent and admiration; the result of which has been to withdraw cognition from an interest in its objects and absorption in the study of them, and to direct it back upon itself; and so turn it to a question of form. Unless we wish to be deceived bywords, it is easy to see what this amounts to. In the case of other instruments, we can try and criticise them in other ways than by setting about the special work for which they are destined. But the examination of knowledge can only be carried out by an act of knowledge. To examine this so-called instrument is the same thing as to know it. But to seek to know before we know is as absurd as the wise resolution of Scholasticus, not to venture into the water until he had learned to swim.
