Johannes Kepler

Astronomy compels the soul to look upwards and leads us from this world to another.

I have attested it as true in my works, and I have done so with a clear conscience, that I have taken the greatest pains to discover the truth.

I have discovered the true distances of the planets, and I have found that they are in the same ratio as the regular solids.

If there are circles in the heavens, they are not perfect circles.

The celestial machine is to be likened not to a divine organism, but rather to a clockwork.

I have tried to show that the celestial machine is not a divine, living being, but rather a clockwork.

The planets move in ellipses, with the sun at one focus.

The line joining a planet and the sun sweeps out equal areas during equal intervals of time.

The square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit.

I have sinned against God, and I am sorry. I have sinned against my neighbor, and I am sorry. I have sinned against myself, and I am sorry.

I have made a discovery that will shake the foundations of astronomy.

The Earth is a great magnet.

The universe is a harmony of spheres.

I have dedicated my life to the study of the heavens.

Truth is the daughter of time, not of authority.

I prefer the criticism of one intelligent man to the applause of the multitude.

The diversity of the works of God is so great that it is impossible to comprehend them all.

I am a Christian, and I believe in God the Father, the Son, and the Holy Spirit.

The more I study the heavens, the more I am convinced that the Earth is a living creature.

I have made a discovery that will change the way we think about the universe.
