>This proposition, if expressed as holding objectively and dogmatically, would read: There is a God. But in fact the proposition entitles us human beings only to this restricted formula: The purposiveness that we must presuppose even for cognizing the inner possibility of many natural things is quite unthinkable to us and is beyond our grasp unless we think of it, and of the world as such, as a product of an intelligent cause (a God).
>Now if this proposition, which is based on an indispensable and necessary maxim of our judgment, is perfectly satisfactory for all speculative and practical uses of our reason from every human point of view, then indeed I would like to know just what we have lost if we cannot also prove it valid for higher beings, i.e., prove it from pure objective bases (to which unfortunately our powers do not extend). For it is quite certain that in terms of merely mechanical principles of nature we cannot even adequately become familiar with, much less explain, organized beings and how they are internally possible. So certain is this that we may boldly state that it is absurd for human beings even to attempt it, or to hope that perhaps some day another Newton might arise who would explain to us, in terms of natural laws unordered by any intention, how even a mere blade of grass is produced. Rather, we must absolutely deny that human beings have such insight.
