Seite 178 - Rather admire; or if they list to try Conjecture, he his fabric of the Heavens Hath left to their disputes, perhaps to move His laughter at their quaint opinions wide Hereafter, when they come to model Heaven And calculate the stars, how they will wield The mighty frame; how build, unbuild, contrive To save appearances; how gird the sphere With centric and eccentric scribbled o'er, Cycle and epicycle, orb in orb...
Seite 425 - Malo me Galatea petit, lasciva puella, et fugit ad salices, et se cupit ante videri.

Seite 36 - Pythagoreans, from the contrasts which number suggests, collected ten principles, — Limited and Unlimited, Odd and Even, One and Many, Right and Left, Male and Female, Rest and Motion, Straight and Curved, Light and Darkness, Good and Evil, Square and Oblong. We shall see hereafter, that Aristotle himself deduced the doctrine of four elements, and other dogmas, by oppositions of the same kind.
Seite 253 - It is not through ignorance of the things admired by them, but through contempt of their useless labour, that we think little of these matters, turning our souls to the exercise of better things.
Seite 410 - And in like manner, when a ray of light falls upon the surface of any pellucid body, and is there refracted or reflected, may not waves of vibrations, or tremors, be thereby excited in the refracting or reflecting medium at the point of incidence...
Seite 511 - This index of refraction is still more materially affected when a body passes from the solid to the liquid, or from the liquid to the gaseous condition...
Seite 40 - Aristotle, in a passage already cited, "decides that there is no void on such arguments as this : in a void there could be no difference of up and down; for as in nothing there are no differences, so there are none in a privation or negation; but a void is merely a privation or negation...
