Side 319 - How sweet the moonlight sleeps upon this bank* Here will we sit, and let the sounds of music Creep in our ears: soft stillness and the night Become the touches of sweet harmony. Sit, Jessica. Look how the floor of heaven Is thick inlaid with patines of bright gold: There's not the smallest orb which thou beholds't But in his motion like an angel sings, Still quiring to the young-eyed cherubins; Such harmony is in immortal souls...
Side 310 - 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.
Side 332 - For REASON, in this sense, is nothing but reckoning, that is adding and subtracting, of the consequences of general names agreed upon for the marking and signifying of our thoughts...
Side 326 - It is not so — It is so — It is not so, crying thus one to another a quarter of an hour together.
Side 310 - 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.
Side 208 - A vague and loose mode of looking at facts very easily observable, left men for a long time under the belief that a body ten times as heavy as another falls ten times as fast; — that objects immersed in water are always magnified, without regard to the form of the surface ; — that the magnet exerts an irresistible force ; — that crystal is always found associated with ice; — and the like.
Side 217 - ... the phenomena of its orbitual motion; but when the effect of this cause is strictly calculated and subducted from the observed motion, there is found to remain behind a residual phenomenon, which would never have been otherwise ascertained to exist, which is a small anticipation of the time of its...
Side 319 - Look how the floor of heaven Is thick inlaid with patines of bright gold. There's not the smallest orb which thou behold'st But in his motion like an angel sings, Still quiring to the young-eyed cherubims : Such harmony is in immortal souls ; But whilst this muddy vesture of decay Doth grossly close it in, we cannot hear it.
Side 218 - I have attempted to characterize; namely, the laws of those Permanent Causes, or indestructible natural agents, which it is impossible either to exclude or to isolate; which we can neither hinder from being present, nor contrive that they shall be present alone.
Side 317 - ... and death, like bodies natural : that after a certain duration of prosperity, they tend spontaneously to decay. This also is a false analogy, because the decay of the vital powers in an animated body can be distinctly traced to the natural progress of those very changes of structure which, in their earlier stages, constitute its growth to maturity...
