"Whether led by reason or by desire alone, no human being does anything except in accordance with the laws and rules of nature." Spinoza Nothing can conceivably act contra naturma, as Spinoza proclaims in Chapter vi "on Miracles" of teh Theorlogical-Political Treatise

so there cannot be a distinction between art and nature.


Spinoza is not intervening in Nature through an act of will to produce lenses conra naturam

Spinoza, his lathe, and the manufactured lenses beahve strictly and solely according to teh Laws of Nature expressed through his and their essence.
