"Each simple substance or Monad is a mirror of the universe according to its point of view."

"Monads have no windows through which anything could enter or depart."

"imaginary numbers are a fine and wonderful resource of the divine intellect, almost an amphibian between being and non-being."

"The monads are the true atoms of nature, and, in a word, the elements of things."

"Justice is nothing else than the charity of the wise."
