Side 193 - 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...
Side 408 - Rise on the earth ; or earth rise on the sun • He from the east his flaming road begin; Or she from west her silent course advance, With inoffensive pace that spinning sleeps On her soft axle, while she paces even, And bears thee soft with the smooth air along; Solicit not thy thoughts with matters hid; Leave them to God above.
Side 42 - 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 . . . Aristotle himself deduced the doctrine of four elements and other dogmas by oppositions of the same kind.
Side 248 - Heaven before, Shrinks to her second cause, and is no more. Physic of metaphysic begs defence, And metaphysic calls for aid on sense! See mystery to mathematics fly! In vain! they gaze, turn giddy, rave, and die. Religion...
Side 408 - The Discovery of a New World ; or, a Discourse tending to prove that it is probable there may be another habitable World in the Moon ; with a Discourse concerning the possibility of a passage thither.
Side 408 - What if the Sun Be Center to the World, and other Starrs By his attractive vertue and thir own Incited, dance about him various rounds? Thir wandring course now high, now low, then hid, Progressive, retrograde, or standing still, In six thou seest, and what if sev'nth to these The Planet Earth, so stedfast though she seem, Insensibly three different Motions move?
Side 46 - 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...
Side 437 - I urged as a thing to be sought; that for which I joined Tycho Brahe, for which I settled in Prague, for which I have devoted the best part of my life to astronomical contemplations ; — at length I have brought to light, and have recognised its truth beyond my most sanguine expectations.
Side 2 - But a just story of learning, containing the antiquities and originals of knowledges and their sects, their inventions, their traditions, their diverse administrations and managings, their flourishings, their oppositions, decays, depressions, oblivions, removes, with the causes and occasions of them, and all other events concerning learning, throughout the ages of the world, I may truly affirm to be wanting.
Side 353 - Egypt; much useful experience had been acquired in the practice of arts and manufactures ; but the science of chemistry owes its origin and improvement to the industry of the Saracens. They first invented and named the alembic for the purposes of distillation, analyzed the substances of the three kingdoms of nature, tried the distinction and affinities of alcalis and acids, and converted the poisonous minerals into soft and salutary medicines.
