Since it is not from knowledge or any scientific reasoning, that we derive the opinion of the necessity of a cause to every new production, that opinion must necessarily arise from observation and experience. The whole aim of the transcendental deduction of all a priori conceptions is to show that these conceptions are a priori conditions of the possibility of all experience. We take from experience nothing more than is requisite to present us with an object (in general) of the external or of the internal sense; in the former case, by the mere conception of matter (impenetrable and inanimate extension), in the latter, by the conception of a thinking being--given in the internal empirical representation, I think. The next degree of these qualities is that derived from the relation of cause and effect; and this too is very great, especially when the conjunction is found by experience to be perfectly constant, and when the object, which is present to us, exactly resembles those, of which we have had experience. We find from experience, that such a degree of passion is usually connected with such a misfortune; and though there be an exception in the present case, yet the imagination is affected by the general rule, and makes us conceive a lively idea of the passion, or rather feel the passion itself, in the same manner, as if the person were really actuated by it. But as regards the principles of ethics, of legislation, and of religion, spheres in which ideas alone render experience possible, although they never attain to full expression therein, he has vindicated for himself a position of peculiar merit, which is not appreciated only because it is judged by the very empirical rules, the validity of which as principles is destroyed by ideas. In this view of the case, the whole field of experience, how far soever it may extend, contains nothing that is not subject to the laws of nature. For the principle of the former enounces, not that things themselves or substances, but only that which happens or their states--as empirically contingent, have a cause; the assertion that the existence of substance itself is contingent is not justified by experience, it is the assertion of a reason employing its principles in a speculative manner.
