Էջ 400 - Cause is the sum total of the Conditions, positive and negative, taken together ; the whole of the contingencies of every description, which, being realized, the consequent invariably follows.
Էջ 367 - As if we could not reason, and have knowledge about particulars: whereas, in truth, the matter rightly considered, the immediate object of all our reasoning and knowledge is nothing but particulars. Every man's reasoning and knowledge is only about the ideas existing in his own mind, which are truly, every one of them...
Էջ 392 - It consists in ascribing the character of general truths to all propositions which are true in every instance that we happen to know of.
Էջ 24 - And a little attention will discover that it is not necessary (even in the strictest reasonings) that significant names which stand for ideas should, every time they are used, excite in the understanding the ideas they are made to stand for : in reading and discoursing, names being for the most part used as letters are in Algebra...
Էջ 283 - He who calls you a man speaks truly: he who calls you a fool, calls you a man: therefore he who calls you a fool speaks truly.

Էջ 305 - objections" against various parts of Scripture ; to some of which no satisfactory answer can be given ; and the incautious hearer is apt, while his attention is fixed on these, to forget that there are infinitely more, and stronger objections against the supposition that the Christian Religion is of human origin ; and that where we cannot answer all objections, we are bound in reason and in candour to adopt the hypothesis which labours under the least.
Էջ 265 - Axiom, as has been shown (page 54), 13 lirectly explicated into the two Laws, — 1. That to affirm the Reason or the Condition is also to affirm the Consequent ; and, 2. That to deny the Consequent is also to deny the Reason. A. ratione ad rationatum, a negatione rationati ad negationem rationis, valet consequentia.
