I am interested in reading a philosophy book titled "Intensive Science And Virtual Philosophy" by Manuel DeLanda. It deals with a new field of philosophy called speculative realism. As I understand it, the meaning of speculative realism is that everything is an object, including sodium atoms, people, colors, and feelings. Correct me if I am wrong here.
DeLanda adopts the realist ontology of Deleuze, where multiplicities replace essences in creating an ontology of objects. This concept map shows the contrast. How would one use the concept of multiplicity to explain how people manipulate objects in the universe, like the ones I mentioned above? Would anyone help me understand DeLanda's book in this regard?
