A difficult, dense, and neglected masterpiece. Belongs on the shelf alongside other great works of metaphysics. It also involves some really wacky and fun moments, such as:
“Through their mediation, the limbs and parts so apparently separated always retain a certain real unity and sympathy, as many examples show, especially the following two. The first is this: if someone without a nose has a nose made for him from the flesh of another man and it is fastened to him like a twig grafted to the trunk of the tree in which it is inserted, when that other man dies and his body rots, that nose also rots and falls from the body of the living man.” (VII, S.4)
“If anyone asks what are these more excellent attributes, I reply that they are the following: spirit or life and light, by which I mean the capacity for every kind of feeling, perception, or knowledge, even love, all power and virtue, joy and fruition, which the noblest creatures have or can have, even the vilest and most contemptible. Indeed, dust and sand are capable of all these perfections through various successive transmutations…” (IX, S.6)
