Note 9 — INTRODUCTION

If we have cause for supposing that concepts which we use as empirical principles stand in relationship with the pure cognitive faculty a priori, it is profitable, because of this reference, to seek for them a transcendental definition; i.e. a definition through pure categories, so far as these by themselves adequately furnish the distinction of the concept in question from others. We here follow the example of the mathematician who leaves undetermined the empirical data of his problem, and only brings their relation in their pure synthesis under the concepts of pure Arithmetic, and thus generalises the solution. Objection has been brought against a similar procedure of mine (cf. the Preface to the Critique of Practical Reason, Abbott’s Translation, p. 94), and my definition of the faculty of desire has been found fault with, viz. that it is [the being’s] faculty of becoming by means of its representations the cause of the actuality of the objects of these representations; for the desires might be mere cravings, and by means of these alone every one is convinced the Object cannot be produced.—But this proves nothing more than that there are desires in man, by which he is in contradiction with himself. For here he strives for the production of the Object by means of the representation alone, from which he can expect no result, because he is conscious that his mechanical powers (if I may so call those which are not psychological) which must be determined by that representation to bring about the Object (mediately) are either not competent, or even tend towards what is impossible; e.g. to reverse the past (O mihi praeteritos ... etc.), or to annihilate in the impatience of expectation the interval before the wished for moment.—Although in such fantastic desires we are conscious of the inadequacy (or even the unsuitability) of our representations for being causes of their objects, yet their reference as causes, and consequently the representation of their causality, is contained in every wish; and this is specially evident if the wish is an affection or longing. For these [longings] by their dilatation and contraction of the heart and consequent exhaustion of its powers, prove that these powers are continually kept on the stretch by representations, but that they perpetually let the mind, having regard to the impossibility [of the desire], fall back in exhaustion. Even prayers for the aversion of great and (as far as one can see) unavoidable evils, and many superstitious means for attaining in a natural way impossible purposes, point to the causal reference of representations to their Objects; a reference which cannot at all be checked by the consciousness of the inadequacy of the effort to produce the effect.—As to why there should be in our nature this propensity to desires which are consciously vain, that is an anthropologico-teleological problem. It seems that if we were not determined to the application of our powers before we were assured of the adequacy of our faculties to produce an Object, these powers would remain in great part unused. For we commonly learn to know our powers only by first making trial of them. This deception in the case of vain wishes is then only the consequence of a benevolent ordinance in our nature.
