Σελίδα 2 - District Clerk's Office. BE IT REMEMBERED, That on the seventh day of May, AD 1828, in the fifty-second year of the Independence of the UNITED STATES OF AMERICA, SG Goodrich, of the said District, has deposited in this office the...

Σελίδα 171 - ... of the powers of our own or of other minds. This reflection ought to be distinguished from consciousness, with which it is too often confounded, even by Mr Locke. All men are conscious of the operations of their own minds, at all times, while they are awake; but there are few who reflect upon them, or make them objects of thought.
Σελίδα 86 - Some of them have moons, that serve to give them light in the absence of the sun, as our moon does to us. They are all, in their motions, subject to the same law of gravitation as the earth is. From all this similitude, it is not unreasonable to think that those planets may, like our earth, be the habitation of various orders of living creatures. There is some probability in this conclusion from analogy.
Σελίδα 160 - RULE 2. The parties should mutually consider each other as standing on a footing of equality, in respect to the subject in debate. Each should regard the other as possessing equal talents, knowledge, and...

Σελίδα 86 - Saturn, Jupiter, Mars, Venus, and Mercury. They all revolve round the sun, as the earth does, although at different distances and in different periods. They borrow all their light from the sun, as the earth does. Several of them are known to revolve round their axis, like the earth ; and by that means must have a like succession of day and night.
Σελίδα 110 - And it must be great want of ingenuity (to say no worse of it) to refuse to do it : since a definition is the only way whereby the precise meaning of moral words can be known ; and yet a way whereby their meaning may be known certainly, and without leaving any room for any contest about it.
Σελίδα 143 - The mind is a thinking substance. A thinking substance is a spirit. A spirit has no composition of parts. That which has no composition of parts is indissoluble. That which is indissoluble is immortal . .•, The mind is immortal.
