Wherever there are qualities there are likewise quantities, but not always vice versa.
Johannes Kepler
Image
Truth is the daughter of time, and I feel no shame in being her midwife.
Johannes Kepler
Image
Geometry is the archetype of the beauty of the world.
Johannes Kepler
Image
I had the intention of becoming a theologian...but now I see how God is, by my endeavors, also glorified in astronomy, for 'the heavens declare the glory of God.'
Johannes Kepler
Image
I am a Lutheran astrologer, I throw away the nonsense and keep the hard kernel.
Johannes Kepler
Image
If the moon and earth were not retained in their orbits by their animal force or some other equivalent, the earth would mount to the moon by a fifty-fourth part of their distance, and the moon fall towards the earth through the other fifty-three parts, and they would there meet, assuming, however, that the substance of both is of the same density.
Johannes Kepler
Image
Yet in this my stars were not Mercury as morning star in the angle of the seventh house, in quartile with Mars, but they were Copernicus, they were Tycho Brahe, without whose books of observations everything which has now been brought by me into the brightest daylight would lie buried in darkness.
Johannes Kepler
Image
Geometry has two great treasures one is the Theorem of Pythagoras the other, the division of a line into extreme and mean ratio. The first we may compare to a measure of gold the second we may name a precious jewel.
Johannes Kepler
Image

Johannes Kepler
Image
The chief aim of all investigations of the external world should be to discover the rational order and harmony which has been imposed on it by God and which He revealed to us in the language of mathematics.
Johannes Kepler
Image
Geometry existed before the creation. It is co-eternal with the mind of God...Geometry provided God with a model for the Creation.
Johannes Kepler
Image
The radius vector describes equal areas in equal times.
Johannes Kepler
Image
Nature loves simplicity and unity.
Johannes Kepler
Image
Just as the eye was made to see colours, and the ear to hear sounds, so the human mind was made to understand, not whatever you please, but quantity.
Johannes Kepler
Image
Thus God himself was too kind to remain idle and began to play the game of signatures signing his likeness unto the world: therefore I chance to think that all nature and the graceful sky are symbolized in the art of Geometria.
Johannes Kepler
Image
Ships and sails proper for the heavenly air should be fashioned. Then there will also be people, who do not shrink from the dreary vastness of space.
Johannes Kepler
Image
Planets move in ellipses with the Sun at one focus.
Johannes Kepler
Image
If the earth were not round, heavy bodies would not tend from every side in a straight line towards the center of the earth, but to different points from different sides.
Johannes Kepler
Image
So long as the mother, Ignorance, lives, it is not safe for Science the offspring, to divulge the hidden causes of things.
Johannes Kepler
Image
The soul of the newly born baby is marked for life by the pattern of the stars at the moment it comes into the world, unconsciously remembers it, and remains sensitive to the return of configurations of a similar kind.
Johannes Kepler
