Pagina 491 - 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...
Pagina 569 - Men, however, in a state of society, are still men ; their actions and passions are obedient to the laws of individual human nature. Men are not, when brought together, converted into another kind of substance, with different properties ; as hydrogen and oxygen are different from water, or as hydrogen, oxygen, carbon, and azote, are different from nerves, muscles, and tendons.
Pagina 258 - Subduct from any phenomenon such part as is known by previous inductions to be the effect of certain antecedents, and the residue of the phenomenon is the effect of the remaining antecedents.
Pagina 211 - To certain facts, certain facts always do, and, as we believe, will continue to, succeed. The invariable antecedent is termed the cause ; the invariable consequent the effect. And the universality of the law of causation consists in this, that every consequent is connected in this manner with some particular antecedent or set of antecedents.

Pagina 440 - D a quality in common with E; — while at the same time no quality can be found which belongs in common to any three objects in the series. Is it not conceivable that the affinity between A and B may produce a transference of the name of the first to the second; and that, in consequence of the other affinities which connect the remaining objects together, the same name may pass in succession from B to C; from C to D; and from D to E...
