Allison Coudert connected a thinker's theory of these things to the kabbalist writings of Francis van Helmont. In a work titled for these things, the fact that the teeth of a brass wheel have bits that "are not artificial" is used to argue that humans are "natural automatons." A work titled for these things describes entering a thinking machine the size of a mill only to find nothing inside to explain its perception. A thinker borrowed Aristotle's term "entelechies" to describe these things, which consist of perception (-5[1])and appetite. These things cannot interact, but mirror each other due (-5[1])to "pre-established harmony." A work titled for these things (10[1])articulates the principles of noncontradiction and sufficient reason. For 10 points, name these windowless particles that make up the (10[1])world (10[1])according to Gottfried (10[1])Leibniz. ■END■ (10[3]0[2])
