Page 96 - ... it is possible we might be affected with all the ideas we have now, though no bodies existed without, resembling them. Hence it is evident the supposition of external bodies is not necessary for the producing our ideas : since it is granted they are produced sometimes, and might possibly be produced always, in the same order we see them in at present, without their concurrence.
Page 211 - ... it is plain that we cannot know the existence of other spirits otherwise than by their operations, or the ideas by them, excited in us. I perceive several motions, changes, and combinations of ideas, that inform me there are certain particular agents, like myself, which accompany them and concur in their production. Hence, the knowledge I have of other spirits is not immediate, as is the knowledge of my ideas; but depending on the intervention of ideas, by me referred to agents or spirits distinct...

Page 94 - Suppose — what no one can deny possible — an intelligence without the help of external bodies, to be affected with the same train of sensations or ideas that you are, imprinted in the same order and with like vividness in his mind. I ask whether that intelligence hath not all the reason to believe the existence of corporeal substances, represented by his ideas, and exciting them in his mind, that you can possibly have for believing the same thing?
Page 305 - I flatter myself that I have discovered an argument of a like nature, which, if just, will, with the wise and learned, be an everlasting check to all kinds of superstitious delusion, and consequently will be useful as long as the world endures...
Page 285 - All mathematical demonstration is built upon the notion, that where quantities or diagrams resemble each other, the relations which are true with respect to one of each kind, will be true with respect to all others of a like kind ; only because there is nothing to make a difference among them. So, if in all past time such
Page 216 - Now the set rules or established methods wherein the Mind we depend on excites in us the ideas of sense, are called the laws of nature; and these we learn by experience, which teaches us that such and such ideas are attended with such and such other ideas, in the ordinary course of things.
