Logic is usually said to be concerned with forms only and to derive the material for them from elsewhere. But this 'only,' which assumes that the logical thoughts are nothing in comparison with the rest of the contents, is not the word to use about forms which are the absolutely-real ground of everything. Everything else rather is an 'only' compared with these thoughts. To make such abstract forms a problem pre-supposes in the inquirer a higher level of culture than ordinary; and to study them in themselves and for their own sake signifies in addition that these thought-types must be deduced out of thought itself, and their truth or reality examined by the light of their own laws. We do not assume them as data from without, and then define them or exhibit their value and authority by comparing them with the shape they take in our minds. If we thus acted, we should proceed from observation and experience, and should, for instance, say we habitually employ the term 'force' in such a case, and such a meaning. A definition like that would be called correct, if it agreed with the conception of its object present in our ordinary state of mind. The defect of this empirical method is that a notion is not defined as it is in and for itself, but in terms of something assumed, which is then used as a criterion and standard of correctness. No such test need be applied: we have merely to let the thought-forms follow the impulse of their own organic life.
To ask if a category is true or not, must sound strange to the ordinary mind: for a category apparently becomes true only when it is applied to a given object, and apart from this application it would seem meaningless to inquire into its truth. But this is the very question on which everything turns. We must however in the first place understand clearly what we mean by Truth. In common life truth means the agreement of an object with our conception of it. We thus pre-suppose an object to which our conception must conform. In the philosophical sense of the word, on the other hand, truth may be described, in general abstract terms, as the agreement of a thought-content with itself. This meaning is quite different from the one given above. At the same time the deeper and philosophical meaning of truth can be partially traced even in the ordinary usage of language. Thus we speak of a true friend; by which we mean a friend whose manner of conduct accords with the notion of friendship. In the same way we speak of a true work of Art. Untrue in this sense means the same as bad, or self-discordant. In this sense a bad state is an untrue state; and evil and untruth may be said to consist in the contradiction subsisting between the function or notion and the existence of the object. Of such a bad object we may form a correct representation, but the import of such representation is inherently false. Of these correctnesses; which are at the same time untruths, we may have many in our heads.—God alone is the thorough harmony of notion and reality. All finite things involve an untruth: they have a notion and an existence, but their existence does not meet the requirements of the notion. For this reason they must perish, and then the incompatibility between their notion and their existence becomes manifest. It is in the kind that the individual animal has its notion: and the kind liberates itself from this individuality by death.
The study of truth, or, as it is here explained to mean, consistency, constitutes the proper problem of logic. In our every-day mind we are never troubled with questions about the truth of the forms of thought.—We may also express the problem of logic by saying that it examines the forms of thought touching their capability to hold truth. And the question comes to this: What are the forms of the infinite, and what are the forms of the finite? Usually no suspicion attaches to the finite forms of thought; they are allowed to pass unquestioned. But it is from conforming to finite categories in thought and action that all deception originates.
(3) Truth may be ascertained by several methods, each of which however is no more than a form. Experience is the first of these methods. But the method is only a form: it has no intrinsic value of its own. For in experience everything depends upon the mind we bring to bear upon actuality. A great mind is great in its experience; and in the motley play of phenomena at once perceives the point of real significance. The idea is present, in actual shape, not something, as it were, over the hill and far away. The genius of a Goethe, for example, looking into nature or history, has great experiences, catches sight of the living principle, and gives expression to it. A second method of apprehending the truth is Reflection, which defines it by intellectual relations of condition and conditioned. But in these two modes the absolute truth has not yet found its appropriate form. The most perfect method of knowledge proceeds in the pure form of thought: and here the attitude of man is one of entire freedom.
That the form of thought is the perfect form, and that it presents the truth as it intrinsically and actually is, is the general dogma of all philosophy. To give a proof of the dogma there is, in the first instance, nothing to do but show that these other forms of knowledge are finite. The grand Scepticism of antiquity accomplished this task when it exhibited the contradictions contained in every one of these forms. That Scepticism indeed went further: but when it ventured to assail the forms of reason, it began by insinuating under them something finite upon which it might fasten. All the forms of finite thought will make their appearance in the course of logical development, the order in which they present themselves being determined by necessary laws. Here in the introduction they could only be unscientifically assumed as something given. In the theory of logic itself these forms will be exhibited, not only on their negative, but also on their positive side.
When we compare the different forms of ascertaining truth with one another, the first of them, immediate knowledge, may perhaps seem the finest, noblest and most appropriate. It includes everything which the moralists term innocence as well as religious feeling, simple trust, love, fidelity, and natural faith. The two other forms, first reflective, and secondly philosophical cognition, must leave that unsought natural harmony behind. And so far as they have this in common, the methods which claim to apprehend the truth by thought may naturally be regarded as part and parcel of the pride which leads man to trust to his own powers for a knowledge of the truth. Such a position involves a thorough-going disruption, and, viewed in that light, might be regarded as the source of all evil and wickedness—the original transgression. Apparently therefore they only way of being reconciled and restored to peace is to surrender all claims to think or know.
This lapse from natural unity has not escaped notice, and nations from the earliest times have asked the meaning of the wonderful division of the spirit against itself. No such inward disunion is found in nature: natural things do nothing wicked.
The Mosaic legend of the Fall of Man has preserved an ancient picture representing the origin and consequences of this disunion. The incidents of the legend form the basis of an essential article of the creed, the doctrine of original sin in man and his consequent need of succour. It may be well at the commencement of logic to examine the story which treats of the origin and the bearings of the very knowledge which logic has to discuss. For, though philosophy must not allow herself to be overawed by religion, or accept the position of existence on sufferance, she cannot afford to neglect these popular conceptions. The tales and allegories of religion, which have enjoyed for thousands of years the veneration of nations, are not to be set aside as antiquated even now.
Upon a closer inspection of the story of the Fall we find, as was already said, that it exemplifies the universal bearings of knowledge upon the spiritual life. In its instinctive and natural stage, spiritual life wears the garb of innocence and confiding simplicity: but the very essence of spirit implies the absorption of this immediate condition in something higher. The spiritual is distinguished from the natural, and more especially from the animal, life, in the circumstance that it does not continue a mere stream of tendency, but sunders itself to self-realisation. But this position of severed life
