Página 296 - ... phenomena depend (a difficulty inherent in the peculiar nature of those phenomena) the science is extremely imperfect; and were it perfect, might probably be of little avail in practice, since the data requisite for applying its principles to particular instances would rarely be procurable. A case may be conceived, of an intermediate character between the perfection of science, and this its extreme imperfection. It may happen that the greater causes, those on which the principal part of the...
Página 296 - Any facts are fitted, in themselves, to be a subject of science, which follow one another according to constant laws ; although those laws may not have been discovered, nor even be discoverable by our existing resources.
Página 32 - ... sed verborum et sententiarum modo interpunctas clausulas in orationibus esse voluerunt; idque princeps Isocrates instituisse fertur, ut inconditam antiquorum dicendi consuetudinem delectationis atque aurium causa, quem ad modum scribit discipulus eius Naucrates, numeris adstringeret.
Página 296 - General laws may be laid down respecting the tides ; predictions may be founded on those laws, and the result will in the main, though often not with complete accuracy, correspond to the predictions. And this is what is, or ought to be, meant by those who speak of sciences which are not exact sciences. Astronomy was once a science, without being an exact science. It could not become exact until not only the general course of the planetary motions, but the perturbations also, were accounted for, and...
Página 129 - ... pleasure ; thought, judgment, conception, and the like? Probably all these would have been placed by the Aristotelian school in the Categories of Actio and Passio ; and the relation of such of them as are active, to their objects, and of such of them as are passive, to their causes, would have been rightly so placed; but the things themselves, the feelings or states of mind, wrongly.
Página 288 - The generalities of the subject have not been altogether neglected by metaphysicians ; but, for want of sufficient acquaintance with the processes by which science has actually succeeded in establishing general truths, their analysis of the inductive operation, even when unexceptionable as to correctness, has not been specific enough to be made the foundation of practical rules, which might be for induction itself what the rules of the syllogism are for the interpretation of induction...
Página 301 - All men are mortal: that the general principle, instead of being given as evidence of the particular case, cannot itself be taken for true without exception, until every shadow of doubt which could affect any case comprised with it, is dispelled by evidence aliunde; and then what remains for the syllogism to prove?
Página 309 - Each science has for its basis a different class of ideas ; and the steps which constitute the progress of one science can never be made by employing the ideas of another kind of science. No genuine advance could ever be obtained in mechanics by applying to the subject the ideas of space and time merely : — no advance in chemistry by the use of mere mechanical conceptions : — no discovery in physiology, by referring facts to mere chemical and mechanical principles.
Página 96 - ... shown to consist (sometimes) of a part directly perceived and a part unperceived (ie inferred).2 Thus the subject of an inference corresponds to Aristotle's Minor Term. As ultimate Subject it corresponds ontologically, to his First Substance or First Essence, « which is a Subject only; it never appears as a predicate of anything else. As Hie Aliquis or Hoc Aliquid it lies at the bottom (either expressed or implied) of all the work of...
