48. oldal - I know thy works, and thy labour, and thy patience, and how thou canst not bear them which are evil : and thou hast tried them which say they are apostles, and are not, and hast found them liars...
450. oldal - That gravity should be innate, inherent, and essential to matter, so that one body may act upon another at a distance through a vacuum, without the mediation of anything else, by and through which their action and force may be conveyed from one to another, is to me so great an absurdity, that I believe no man, who has in philosophical matters a competent faculty of thinking, can ever fall into it.
448. oldal - But hitherto I have not been able to discover the cause of those properties of gravity from phenomena, and I frame no hypotheses. For whatever is not deduced from the phenomena is to be called an hypothesis, and hypotheses, whether metaphysical or physical, whether of occult qualities or mechanical, have no place in experimental philosophy.

25. oldal - THERE rolls the deep where grew the tree. O earth, what changes hast thou seen ! There where the long street roars, hath been The stillness of the central sea. The hills are shadows, and they flow From form to form, and nothing stands ; They melt like mist, the solid lands, Like clouds they shape themselves and go.

398. oldal - FROM low to high doth dissolution climb, And sink from high to low, along a scale Of awful notes, whose concord shall not fail ; A musical but melancholy chime, Which they can hear who meddle not with crime, Nor avarice, nor over-anxious care.
450. oldal - It is inconceivable, that inanimate brute matter should, without the mediation of something else, which is not material, operate upon, and affect other matter without mutual contact; as it must do, if gravitation, in the sense of Epicurus, be essential and inherent in it.
