Hence, even Critical Idealism can proceed in a twofold manner. Either it deduces this system of necessary modes of action, and together with it the objective representations arising therefrom, really from the fundamental laws of the Intelligence, and thus causes gradually to arise under the very eyes of the reader or hearer the whole extent of our representations; or it gathers these laws—perhaps as they are already immediately applied to objects; hence, in a lower condition, and then they are called categories—gathers these laws somewhere, and now asserts, that the objects are determined and regulated by them. I ask the critic who follows the last-mentioned method, and who does not deduce the assumed laws of the Intelligence from the Essence of the Intelligence, where he gets the material knowledge of these laws, the knowledge that they are just these very same laws; for instance, that of Substantiality or Causality? For I do not want to trouble him yet with the question, how he knows that they are mere immanent laws of the Intelligence. They are the laws which are immediately applied to objects, and he can only have obtained them by abstraction from these objects, i. e. from Experience. It is of no avail if he takes them, by a roundabout way, from logic, for logic is to him only the result of abstraction from the objects, and hence he would do indirectly, what directly might appear too clearly in its true nature. Hence he can prove by nothing that his postulated Laws of Thinking are really Laws of Thinking, are really nothing but immanent laws of the Intelligence. The Dogmatist asserts in opposition, that they are not, but that they are general qualities of Things, founded on the nature of Things, and there is no reason why we should place more faith in the unproved assertion of the one than in the unproved assertion of the other. This course of proceeding, indeed, furnishes no understanding that and why the Intelligence should act just in this particular manner. To produce such an understanding, it would be necessary to premise something which can only appertain to the Intelligence, and from those premises to deduce before our eyes the laws of Thinking. By such a course of proceeding it is above all incomprehensible how the object itself is obtained; for although you may admit the unproved postulates of the critic, they explain nothing further than the _qualities_ and _relations_ of the Thing: (that it is, for instance, in space, manifested in time, with accidences which must be referred to a substance, &c.) But whence that which has these relations and qualities? whence then the substance which is clothed in these forms? This substance Dogmatism takes refuge in, and you have but increased the evil.
