Our reasonings are grounded upon two great principles, that of contradiction, in virtue of which we judge false that which involves a contradiction, and true that which is opposed or contradictory to the false.

God's relation to spirits is not like that of a craftsman to his work, but also like that of a prince to his subjects.
Gottfried Leibniz
Image
But it is the knowledge of necessary and eternal truths which distinguishes us from mere animals, and gives us reason and the sciences, raising us to knowledge of ourselves and God. It is this in us which we call the rational soul or mind.
Gottfried Leibniz
Image
I am so in favor of the actual infinite that instead of admitting that Nature abhors it, as is commonly said, I hold that Nature makes frequent use of it everywhere, in order to show more effectively the perfections of its Author.
Gottfried Leibniz
Image
For things remain possible, even if God does not choose them. Indeed, even if God does not will something to exist, it is possible for it to exist, since, by its nature, it could exist if God were to will it to exist.

The pleasure we obtain from music comes from counting, but counting unconsciously. Music is nothing but unconscious arithmetic.
Gottfried Leibniz
Image
It is God who is the ultimate reason things, and the Knowledge of God is no less the beginning of science than his essence and will are the beginning of things.
Gottfried Leibniz
Image
There never is absolute birth nor complete death, in the strict sense, consisting in the separation of the soul from the body. What we call births are developments and growths, while what we call deaths are envelopments and diminutions.
Gottfried Leibniz
Image
Philosophy consists mostly of kicking up a lot of dust and then complaining that you can't see anything.
Gottfried Leibniz
Image
Nothing is more important than to see the sources of invention which are, in my opinion more interesting than the inventions themselves.
Gottfried Leibniz
Image
There is no way in which a simple substance could begin in the course of nature, since it cannot be formed by means of compounding.
Gottfried Leibniz
Image
God makes nothing without order, and everything that forms itself develops imperceptibly out of small parts.
Gottfried Leibniz
Image
Make me the the master of education, and I will undertake to change the world.
Gottfried Leibniz
Image
Either there are no corporeal substances, and bodies are merely phenomena which are true or consistent with each other, such as a rainbow or a perfectly coherent dream, or there is in all corporeal substances something analogous to the soul.
Gottfried Leibniz
Image
The present is big with the future, the future might be read in the past, the distant is expressed in the near.
Gottfried Leibniz
Image
He who understands Archimedes and Apollonius will admire less the achievements of the foremost men of later times.
Gottfried Leibniz

There is nothing without reason.
Gottfried Leibniz
Image
I have seen something of the project of M. de St. Pierre, for maintaining a perpetual peace in Europe. I am reminded of a device in a cemetery, with the words: Pax perpetua for the dead do not fight any longer: but the living are of another humor and the most powerful do not respect tribunals at all.
Gottfried Leibniz

It is unworthy of excellent men to lose hours like slaves in the labor of calculation which could be relegated to anyone else if machines were used.
Gottfried Leibniz
Image
I also take it as granted that every created thing, and consequently the created monad also, is subject to change, and indeed that this change is continual in each one.
Gottfried Leibniz
Image
The present is saturated with the past and pregnant with the future.
