Gottfried Wilhelm Leibniz — "The present is big with the future."

"I have said more than once, that I hold space to be something merely relative, as time is; that I hold it to be an order of coexistences, as time is an order of successions."

"The universe is a machine, but a divine machine."

"The mind is not only capable of knowing [innate ideas], but further of finding them in itself; and if it had only the simple capacity to receive knowledge…it would not be the source of necessary truth…"

"Music is the hidden arithmetical exercise of a mind unconscious that it is calculating."

"The pleasure we obtain from music comes from counting, but counting unconsciously. Music is nothing but unconscious arithmetic."
