Musica est exercitium arithmeticae occultum nescientis se numerare animi. - Gottfried Wilhelm Leibniz

...as far as we are capable of knowledge we sin in neglecting to acquire it...

Ainsi on peut dire que non seulement l'âme, miroir d'un univers indestructible, est indestructible, mais encore l'animal même, quoique sa machine périsse souvent en partie, et quitte ou prenne des dépouilles organiques.

This connection of all created things with every single one of them and their adaptation to every single one, as well as the connection and adaptation of every single thing to all others, has the result that every single substance stands in relations which express all the others. Whence every single substance is a perpetual living mirror of the universe.
