See for yourself. If we do not set out from experience, or do not proceed according to the laws of the empirical connection of phenomena, our pretensions to discover the existence of a thing which we do not immediately perceive are vain. The above judgement is complete evidence that we are accustomed to think that reason is not affected by sensuous conditions, that in it no change takes place--although its phenomena, in other words, the mode in which it appears in its effects, are subject to change--that in it no preceding state determines the following, and, consequently, that it does not form a member of the series of sensuous conditions which necessitate phenomena according to natural laws. to derive its obligation from those laws of nature, and, in particular, from that concerning the performance of promises. Fourthly, the conceptions of the possible, the actual, and the necessary do not conduct us to any series--excepting only in so far as the contingent in existence must always be regarded as conditioned, and as indicating, according to a law of the understanding, a condition, under which it is necessary to rise to a higher, till in the totality of the series, reason arrives at unconditioned necessity. We have found, it is true, that the systematic unity of nature could not be established according to speculative principles of reason, because, while reason possesses a causal power in relation to freedom, it has none in relation to the whole sphere of nature; and, while moral principles of reason can produce free actions, they cannot produce natural laws. It is quite possible that someone may propose a species of preformation-system of pure reason--a middle way between the two--to wit, that the categories are neither innate and first a priori principles of cognition, nor derived from experience, but are merely subjective aptitudes for thought implanted in us contemporaneously with our existence, which were so ordered and disposed by our Creator, that their exercise perfectly harmonizes with the laws of nature which regulate experience.
