Sayings by Gottfried Wilhelm Leibniz
We live in the best of all possible worlds.
There are also two kinds of truths: those of reasoning and those of fact. Truths of reasoning are necessary and their opposite is impossible; truths of fact are contingent and their opposite is possible.
Everything that is possible demands to exist.
Monads have no windows through which anything could enter or depart.
Pre-established harmony is the only way to explain the agreement of substances without their interaction.
The present is big with the future.
Each simple substance or Monad is a mirror of the universe according to its point of view.
Nothing is without a reason.
The actual world is the most perfect of all possible worlds.
It is not the eye that sees, but the mind.
The soul is the mirror of an indestructible universe.
God is the ultimate reason of things.
The universe, if it were not composed of monads, would be a mere aggregate, not a substance.
The monad is nothing but a simple substance that enters into composites.
God has chosen the best of all possible worlds, not because it is the most perfect in every respect, but because it is the most perfect in the whole.
To be is to be a value.
Each soul is a little world, a microcosm.
Nature makes no leaps.
The monads have no parts.
The soul is a living mirror of the universe.
