| In this manner, there arise exactly so many pure conceptions of the understanding, applying a priori to objects of intuition in general, as there are logical functions in all possible judgements. |
| For there is no other function or faculty existing in the understanding besides those enumerated in that table. |
| These conceptions we shall, with Aristotle, call categories, our purpose being originally identical with his, notwithstanding the great difference in the execution. |
| TABLE OF THE CATEGORIES |
| | 1 | Of Quantity | Unity | Reality | Plurality | | 2 | Of Quality | Negation | Totality | Limitation | | 3 | Of Relation | Of Inherence and Subsistence (substantia et accidens) | Of Causality and Dependence (cause and effect) | Of Community (reciprocity between the agent and patient) | | 4 | Of Modality | Possibility--Impossibility | Existence--Non-existence | Necessity--Contingence |
|
| This, then, is a catalogue of all the originally pure conceptions of the synthesis which the understanding contains a priori, and these conceptions alone entitle it to be called a pure understanding; inasmuch as only by them it can render the manifold of intuition conceivable, in other words, think an object of intuition. |
| This division is made systematically from a common principle, namely the faculty of judgement (which is just the same as the power of thought), and has not arisen rhapsodically from a search at haphazard after pure conceptions, respecting the full number of which we never could be certain, inasmuch as we employ induction alone in our search, without considering that in this way we can never understand wherefore precisely these conceptions, and none others, abide in the pure understanding. |
| It was a design worthy of an acute thinker like Aristotle, to search for these fundamental conceptions. |
| Destitute, however, of any guiding principle, he picked them up just as they occurred to him, and at first hunted out ten, which he called categories (predicaments). |
| Afterwards be believed that he had discovered five others, which were added under the name of post predicaments. |
| But his catalogue still remained defective. |
| Besides, there are to be found among them some of the modes of pure sensibility (quando, ubi, situs, also prius, simul), and likewise an empirical conception (motus)--which can by no means belong to this genealogical register of the pure understanding. |
| Moreover, there are deduced conceptions (actio, passio) enumerated among the original conceptions, and, of the latter, some are entirely wanting. |
| With regard to these, it is to be remarked, that the categories, as the true primitive conceptions of the pure understanding, have also their pure deduced conceptions, which, in a complete system of transcendental philosophy, must by no means be passed over; though in a merely critical essay we must be contented with the simple mention of the fact. |
| Let it be allowed me to call these pure, but deduced conceptions of the understanding, the predicables of the pure understanding, in contradistinction to predicaments. |
| If we are in possession of the original and primitive, the deduced and subsidiary conceptions can easily be added, and the genealogical tree of the understanding completely delineated. |
| As my present aim is not to set forth a complete system, but merely the principles of one, I reserve this task for another time. |
| It may be easily executed by any one who will refer to the ontological manuals, and subordinate to the category of causality, for example, the predicables of force, action, passion; to that of community, those of presence and resistance; to the categories of modality, those of origination, extinction, change; and so with the rest. |
| The categories combined with the modes of pure sensibility, or with one another, afford a great number of deduced a priori conceptions; a complete enumeration of which would be a useful and not unpleasant, but in this place a perfectly dispensable, occupation. |
| I purposely omit the definitions of the categories in this treatise. |
| I shall analyse these conceptions only so far as is necessary for the doctrine of method, which is to form a part of this critique. |
