Page 103 - ... that in some one for instance of the many firmaments into which sidereal astronomy now divides the universe, events may succeed one another at random, without any fixed law ; nor can anything in our experience, or in our mental nature, constitute a sufficient, or indeed any, reason for believing that this is nowhere the case.
Page 46 - All inference is from particulars to particulars; general propositions are merely registers of such inferences already made, and short formulae for making more; the major premise of a syllogism, consequently, is a formula of this description, and the conclusion is not an inference drawn from the formula, but an inference drawn according to the formula, the real logical antecedent, or premise, being the particular facts from which the general proposition was collected by induction.
Page 146 - ... supprimée, un ordre tel que la première appelât la seconde et la seconde la troisième; s'il établissait ainsi que la quantité pure est le commencement nécessaire de la nature, et que la pensée est le terme extrême auquel la nature est tout entière suspendue...
Page 100 - Why these particular natural agents existed originally and no others, or why they are commingled in such and such proportions, and distributed in such and such a manner throughout space, is a question we cannot answer. More than this : we can discover nothing regular in the distribution itself ; we can reduce it to no uniformity, to no law.
Page 74 - ... the condition necessary to bring the Method of Difference into play. " 'Now, first, no dew is produced on the surface of polished metals, but it is very copiously on glass, both exposed with their faces upwards, and in some cases the under side of a horizontal plate of glass is also dewed.
Page 76 - " But if we expose rough surfaces instead of polished, we sometimes find this law interfered with. Thus, roughened iron, especially if painted over or blackened, becomes dewed sooner than varnished paper : the kind of surface, therefore, has a great influence. Expose, then, the same material in very diversified states as to surface...
Page 147 - ... suspendue; si ensuite , isolant les éléments de ces données, il montrait qu'ils doivent se combiner comme ils sont combinés, et non autrement ; s'il prouvait enfin qu'il n'ya point d'autres éléments, et qu'il ne peut y en avoir d'autres , il aurait esquissé une métaphysique sans em].
Page 104 - The uniformity in the succession of events, otherwise called the law of causation, must be received, not as a law of the universe, but of that portion of 1 Logic, III.
Page 80 - ... radiate heat rapidly or conduct it slowly : qualities between which there is no other circumstance of agreement, than that by virtue of either, the body tends to lose heat from the surface more rapidly than it can be restored from within. The instances, on the contrary, in which no dew, or but a small quantity of it, is formed, and which are also extremely various, agree (as far as we can observe) in nothing except in not having this same property.
Page 86 - Here, too, therefore, the causation is directly proved. We can, it is true, accomplish this only on a small scale; but we have ample reason to conclude that the same operation, if conducted in Nature's great laboratory, would equally produce the effect. " And, finally, even on that great scale we are able to verify the result. The case is one of those rare cases, as we have shown them to be, in which nature works the experiment for us. in the same manner in which we ourselves perform it; introducing...
