These would all be possible; but being all equally possible, he would never of himself give a satisfactory account for his preferring one of them to the rest.

Experience alone can point out to him the true cause of any phenomenon.
Now, according to this method of reasoning, DEMEA, it follows, (and is, indeed, tacitly allowed by CLEANTHES himself,) that order, arrangement, or the adjustment of final causes, is not of itself any proof of design; but only so far as it has been experienced to proceed from that principle.

For aught we can know a priori, matter may contain the source or spring of order originally within itself, as well as mind does; and there is no more difficulty in conceiving, that the several elements, from an internal unknown cause, may fall into the most exquisite arrangement, than to conceive that their ideas, in the great universal mind, from a like internal unknown cause, fall into that arrangement.

The equal possibility of both these suppositions is allowed.

But, by experience, we find, (according to CLEANTHES), that there is a difference between them.
