GottfriedLeibniz

The best of all possible web pages,we have WindowlessMonads as well as Monads with a view.

Yet, in the 'best of all possible web pages' Monads can

well afford not to have windows: They know anyway what

is going on elsewhere, or atually, they have always

known it. (By means of that 'prestabilized harmony'

Leibniz avoids the problem to explain how mind affects

matter and vice versa. "Car je ne trouvois aucun moyen

d'expliquer comment le corps fait passer quelque chose

dans l'ame , ou vice versa, ny comment une substance

peut communiquer avec une autre substance creee."

Systeme Nouveau de la Nature etc.(12). Descartes'

followers had introduced the "Systeme des Causes

occasionelles" to solve the problem: God creates

movements according to our will to move, and

thoughts according to movements of exterior things.

The idea of a God permanently busy to maintain

the harmony of the universe seemed much less

attractive to Leibniz then the harmony established

once for all. --- )
