But if I insist on basing nature upon the foundation of a supreme ordaining Being, the unity of nature is in effect lost. For such certainty cannot be found in an a posteriori proposition; and the conceptions a priori of space and time are, according to this opinion, mere creations of the imagination, having their source really in experience, inasmuch as, out of relations abstracted from experience, imagination has made up something which contains, indeed, general statements of these relations, yet of which no application can be made without the restrictions attached thereto by nature. In the former sense we speak of the nature of liquid matter, of fire, etc., and employ the word only adjective; while, if speaking of the objects of nature, we have in our minds the idea of a subsisting whole.] Besides, we find in the course of nature, that though the effects be many, the principles, from which they arise, are commonly but few and simple, and that it is the sign of an unskilful naturalist to have recourse to a different quality, in order to explain every different operation. For as princes do actually form treaties among themselves, they must propose some advantage from the execution of them; and the prospect of such advantage for the future must engage them to perform their part, and must establish that law of nature. Or if they esteem that opinion absurd and impious, as it really is, I shall tell them how they may avoid it; and that is, by concluding from the very first, that they have no adequate idea of power or efficacy in any object; since neither in body nor spirit, neither in superior nor inferior natures, are they able to discover one single instance of it. For this conception demands that something, A, should be of such a nature that something else, B, should follow from it necessarily, and according to an absolutely universal law. For, although in respect to the theoretical cognition of the universe I do not require to form any theory which necessarily involves this idea, as the condition of my explanation of the phenomena which the universe presents, but, on the contrary, am rather bound so to use my reason as if everything were mere nature, still teleological unity is so important a condition of the application of my reason to nature, that it is impossible for me to ignore it--especially since, in addition to these considerations, abundant examples of it are supplied by experience.
