Gottfried Wilhelm Leibniz

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

Nothing is without a reason.

There are also two kinds of truths: those of reasoning and those of fact.

The present is big with the future.

God is the ultimate reason of things.

This is why the present is big with the future and laden with the past.

The monads have no windows through which anything could enter or leave.

And this is the best of all possible worlds.

God is the first reason of things.

To love God is to love all things.

The actual world is the best of all possible worlds.

The true reason why evil exists is that it is a necessary ingredient in the best possible world.

Nothing is in the intellect that was not first in the senses, except the intellect itself.

The art of discovering the causes of phenomena, or true hypotheses, is like the art of deciphering, where an ingenious conjecture often greatly shortens the work.

Music is a hidden arithmetical exercise of the soul, which does not know that it is counting.

The more I study nature, the more I am amazed at the Creator.

I am so much in favor of the method of analysis and synthesis that I believe it should be applied to all sciences.

The mind is not a tabula rasa.

The present is pregnant with the future.

The actual world is the most perfect of all possible worlds.
