So each person is a monad, and there is no causation between monads. Perception occurs as a result of aggregation of monads. The aggregation between them gives the perception. My question is, if each monad is "a window to universe", a perspective, each monad is an indivisible immaterial substance which contains all the predicates of it, then how can we say the people share the same perception? Why do I an my friend perceive that this is a chair and do not perceive it differently?
Help would be much appreciated!
Thanks in advance!
