Nature is very consonant and conformable with herself.

Errors are not in the art but in the artificers.

How came the bodies of animals to be contrived with so much art, and for what ends were their several parts?

Hypotheses non fingo. I frame no hypotheses.

Blind metaphysical necessity, which is certainly the same always and every where, could produce no variety of things. All that diversity of natural things which we find suited to different times and places could arise from nothing but the ideas and will of a Being, necessarily existing.
