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.

More quotes by Gottfried Leibniz

Image
Natural religion itself, seems to decay very much. Many will have human souls to be material: others make God himself a corporeal being.
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
Nothing is accomplished all at once, and it is one of my great maxims, and one of the most completely verified, that Nature makes no leaps: a maxim which I have called the law of continuity.
Gottfried Leibniz
Image
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
Make me the the master of education, and I will undertake to change the world.
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
Image
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
A great doctor kills more people than a great general.
Gottfried Leibniz
Image
God makes nothing without order, and everything that forms itself develops imperceptibly out of small parts.
Gottfried Leibniz
Image
Why is there anything at all rather than nothing whatsoever?
Gottfried Leibniz
Image
To love is to place happiness in the heart of another.
Gottfried Leibniz
Image
I hold that it is only when we can prove everything we assert that we understand perfectly the thing under consideration.
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
The world is not a machine. Everything in it is force, life, thought.
Gottfried Leibniz
Image
For since it is impossible for a created monad to have a physical influence on the inner nature of another, this is the only way in which one can be dependent on another.
Gottfried Leibniz
Image
I am convinced that the unwritten knowledge scattered among men of different callings surpasses in quantity and in importance anything we find in books, and that the greater part of our wealth has yet to be recorded.
Gottfried Leibniz
Image
In whatever manner God created the world, it would always have been regular and in a certain general order. God, however, has chosen the most perfect, that is to say, the one which is at the same time the simplest in hypothesis and the richest in phenomena.
Gottfried Leibniz
Image
He who understands Archimedes and Apollonius will admire less the achievements of the foremost men of later times.
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
There is nothing without reason.
Gottfried Leibniz
