Página 22 - 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...
Página 445 - Several writers have misapprehended or objected to the term Natural Selection. Some have even imagined that natural selection induces variability, whereas it implies only the preservation of such variations as arise and are beneficial to the being under its conditions of life.

But the length of the wave emitted by the fork is 52 inches ; hence the length of the column of air which resounds to the fork is equal to one-fourth of the length of the wave produced by the fork. This rule is general, and might be illustrated by any other of the forks instead of this one.
Página 500 - Why should not Nature take a sudden leap from structure to structure ? On the theory of natural selection, we can clearly understand why she should not; for natural selection acts only by taking advantage of slight successive variations ; she can never take a great and sudden leap, but must advance by short and sure, though slow steps.
Página 43 - By faith we understand that the worlds were framed by the word of God, so that things which are seen were not made of things which do appear.
Página 410 - Each living creature must be looked at as a microcosm — a little universe, formed of a host of self-propagating organisms, inconceivably minute and as numerous as the stars in heaven.
