It only proves that according to the constitution of our cognitive faculties and in the consequent combination of experience with the highest principles of Reason, we can form absolutely no concept of the possibility of such a world [as this] save by thinking a designedly-working supreme cause thereof. Objectively we cannot therefore lay down the proposition, there is an intelligent original Being; but only subjectively, for the use of our Judgement in its reflection upon the purposes in nature, which can be thought according to no other principle than that of a designing causality of a highest cause.

If we wished to establish on teleological grounds the above proposition dogmatically we should be beset with difficulties from which we could not extricate ourselves.
