“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.”

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.

A great doctor kills more people than a great general.

The past is pregnant with the present.

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.

What is what must be.

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.

The knowledge which we have acquired ought not to resemble a great shop without order, and without an inventory; we ought to know what we possess, and be able to make it serve us in need.

Nature does not make leaps.

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.

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.

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

Men act like brutes in so far as the sequences of their perceptions arise through the principle of memory only, like those empirical physicians who have mere practice without theory.

There is nothing waste, nothing sterile, nothing dead in the universe; no chaos, no confusions, save in appearance.

Imaginary numbers are a fine and wonderful refuge of the divine spirit almost an amphibian between being and non-being.

All things in God are spontaneous.

And there must be simple substances, because there are compounds; for the compound is nothing but a collection or aggregatum of simples.

The success of each is dependent upon the success of the other.

Many players are of the same standard; it all depends on how your strokes land on the other side of court.

The truth of life is that, even the doctor needs a doctor.

When I turn my mind’s eye upon myself, I understand that I am a thing which is incomplete and dependent on another and which aspires without limit to ever greater and better things…

Peace in society depends upon peace in the family.

I love, because my love is not dependent on the object of love. My love is dependent on my state of being.

When love flows with freedom there is beauty. When love flows with dependence there is ugliness.

Sin is believing the lie that you are self-created, self-dependent and self-sustained.
