Side 372 - One science only will one genius fit ; So vast is art, so narrow human wit : Not only bounded to peculiar arts, But oft in those confined to single parts.
Side 275 - I do not know what I may appear to the world ; but to myself I seem to have been only like a boy playing on the sea-shore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me.
Side 96 - I think it may not be amiss to take notice, that however faith be opposed to reason, faith is nothing but a firm assent of the mind : which if it be regulated, as is our duty, cannot be afforded to any thing but upon good reason ; and so cannot be opposite to it. He that believes, without having any reason for believing, may be in love with his own fancies; but neither seeks truth as he ought, nor pays the obedience due to his Maker...
Side 293 - It is a pleasure to stand upon the shore and to see ships tossed upon the sea; a pleasure to stand in the window of a castle and to see a battle and the adventures thereof below; but no pleasure is comparable to the standing upon the vantage ground of truth...
Side 285 - Our business was (precluding matters of theology and state affairs) to discourse and consider of philosophical enquiries, and such as related thereunto: — as Physick, Anatomy, Geometry, Astronomy, Navigation, Staticks, Magneticks, Chymicks, Mechanicks, and Natural Experiments; with the state of these studies and their cultivation at home and abroad.
Side 181 - ... by art, seems to be done with equal efficacy, though more slowly, by nature, in the formation of varieties of mankind, fitted for the country which they inhabit. Of the accidental varieties of man, which would occur among the first few and scattered inhabitants of the middle regions of Africa, some one would be better fitted than the others to bear the diseases of the country.
Side 285 - Saturn, the spots in the sun, and its turning on its own axis", the inequalities and selenography of the moon, the several phases of Venus and Mercury, the improvement of telescopes, and grinding of glasses for that purpose, the weight of air, the possibility, or impossibility of vacuities, and nature's abhorrence thereof, the Torricellian experiment in quicksilver, the descent of heavy bodies, and the degrees of acceleration therein ; and divers other things of like nature.
Side 293 - ... (a hill not to be commanded, and where the air is always clear and serene) " and to see the errors, and wanderings, and mists, and tempests in the vale below.
Side 177 - Now what these several degrees are I have not yet experimentally verified; but it is a notion, which if fully prosecuted as it ought to be, will mightily assist the Astronomer to reduce all the Coelestial Motions to a certain rule, which I doubt will never be done true without it.
Side 366 - I felt that it might be worth my while to expend the labour of at least ten (or it might be fifteen) years to come. But then it is fair to say that this was because I felt a problem to have been at that moment solved — an intellectual want relieved — which had haunted me for at least fifteen years before.
