If we were magically shrunk and put into someone's brain while she was thinking, we would see all the pumps, pistons, gears and levers working away and we would be able to describe the workings completely.

Gottfried Wilhelm Leibniz

We never have a full demonstration, although there is always an underlying reason for the truth, even if it is only perfectly understood by God, who alone penetrated the infinite series in one stroke of the mind.

Gottfried Wilhelm Leibniz

The greatness of a life can only be estimated by the multitude of its actions. We should not count the years, it is our actions which constitute our life.

Gottfried Wilhelm Leibniz

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

Gottfried Wilhelm Leibniz

The soul is the mirror of an indestructible universe. The Monadology.

Gottfried Wilhelm Leibniz

In mechanical terms, thereby completely describing the thought processes of the brain. But that description would not contain any mention of thought! It would contain nothing but descriptions of pumps, pistons, levers!

Gottfried Wilhelm Leibniz

If you have a clear idea of a soul, you will have a clear idea of a form; for it is of the same genus, though a different species.

Gottfried Wilhelm Leibniz

There is a certain destiny of everything, regulated by the foreknowledge and providence of God in His works.

Gottfried Wilhelm Leibniz

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

Gottfried Wilhelm Leibniz

Every mind has a horizon in respect to its present intellectual capacity but not in respect to its future intellectual capacity.

Gottfried Wilhelm Leibniz

Music is the pleasure the human mind experiences from counting without being aware that it is counting.

Gottfried Wilhelm Leibniz

Every present state of a simple substance is the natural consequence of its preceding state, in such a way that its present is big with its future.
