Every thing which begins to exist must have a cause: every combination, conspiring to an end, implies intelligence.

EUSEBES.

Design must be proved before a designer can be inferred. The matter in controversy is the existence of design in the Universe, and it is not permitted to assume the contested premises and thence infer the matter in dispute. Insidiously to employ the words contrivance, design and adaptation before these circumstances are made apparent in the Universe, thence justly inferring[1] a contriver, is a popular sophism against which it behoves us to be watchful.

To assert that motion is an attribute of mind, that matter is inert, that every combination is the result of intelligence is also an assumption of the matter in dispute.

Why do we admit design in any machine of human contrivance? Simply, because innumerable instances of machines having been contrived by human art are present to our mind, because we are acquainted with persons who could construct such machines; but if, having no previous knowledge of any artificial contrivance, we had accidentally found a watch upon the ground, we should have been justified in concluding that it was a thing of Nature, that it was a combination of matter with whose cause we were unacquainted, and that any attempt to account for the origin of its existence would be equally presumptuous and unsatisfactory.

  1. In the original, infering.
