A System of Logic, by John Stuart Mill

Book III.

Of induction.

“According to the doctrine now stated, the highest, or rather the only proper object of physics, is to ascertain those established conjunctions of successive events, which constitute the order of the universe; to record the phenomena which it exhibits to our observations, or which it discloses to our experiments; and to refer these phenomena to their general laws.” — D. STEWART, Elements of the Philosophy of the Human Mind, vol. ii., chap. iv., sect. 1.

“In such cases the inductive and deductive methods of inquiry may be said to go hand in hand, the one verifying the conclusions deduced by the other; and the combination of experiment and theory, which may thus be brought to bear in such cases, forms an engine of discovery infinitely more powerful than either taken separately. This state of any department of science is perhaps of all others the most interesting, and that which promises the most to research.” — SIR J. HERSCHEL, Discourse on the Study of Natural Philosophy.
