There is a force in the earth which causes the moon to move. — Johannes Kepler

"Either... the moving intelligences of the planets are weakest in those that are farthest from the sun, or... there is one moving intelligence in the sun, the common center, forcing them all round, but those most violently which are nearest, and that it languishes in some sort and grows weaker at the most distant, because of the remoteness and the attenuation of the virtue."

"I believe it was an act of Divine Providence that I arrived just at the time when Longomontanus [Tycho Brahes assistant before Kepler] was occupied with Mars. For Mars alone enables us to penetrate the secrets of astronomy which otherwise would remain forever hidden from us."

"In Terra inest virtus, quae Lunam del."

"I used to measure the heavens, now I measure the shadows of Earth. Although my mind was heaven-bound, the shadow of my body lies here."

"Geometry has two great treasures: one is the Theorem of Phythagoras, the other the division of a line in extreme and mean ratio. The first we can compare to a mass of gold; the other we may call a precious jewel."

"Temporis filia veritas; cui me obstetricari non pudet."

"Now Art, used collectively for painting, sculpture, architecture and music, is the mediatress between, and reconciler of, nature and man. It is, therefore, the power of humanizing nature, of infusing the thoughts and passions of man into everything which is the object of his contemplation."

"The Good consists in the congruity of a thing with the laws of the reason and the nature of the will, and in its fitness to determine the latter to actualize the former: and it is always discursive. The Beautiful arises from the perceived harmony of an object, whether sight or sound, with the inborn and constitutive rules of the judgment and imagination: and it is always intuitive."

"I believe that the unity of man as opposed to other living things derives from the fact that man is the conscious life of himself. Man is conscious of himself, of his future, which is death, of his smallness, of his impotence; he is aware of others as others; man is in nature, subject to its laws even if he transcends it with his thought."

"Who made you glorious as the gates of heaven Beneath the keen full moon? Who bade the sun Clothe you with rainbows? Who, with living flower Of loveliest blue, spread garlands at your feet? God! let the torrents, like a shout of nations, Answer! and let the ice-plains echo, God! God! sing, ye meadow-streams, with gladsome voice! Ye pine-groves, with your soft and soul-like sounds! And they too have a voice, yon piles of snow, And in their perilous fall shall thunder, God!"

"All Nature seems at work. Slugs leave their lair — The bees are stirring — birds are on the wing — And Winter slumbering in the open air, Wears on his smiling face a dream of Spring! And I the while, the sole unbusy thing, Nor honey make, nor pair, nor build, nor sing."

"Taste is the intermediate faculty which connects the active with the passive powers of our nature, the intellect with the senses; and its appointed function is to elevate the images of the latter, while it realizes the ideas of the former."
