الصفحة ii - 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...
الصفحة 96 - The first sentence where the word occurs, affords, it is probable, sufficient foundation for a vague conjecture concerning the notion annexed to it by the author ; — some idea or other being necessarily substituted in its place, in order to make the passage at all intelligible. The next sentence where it is involved, renders this conjecture a little more definite ; a third sentence contracts the field of doubt within still narrower limits ; till, at length, a more extensive induction fixes completely...
الصفحة 167 - Since it is the understanding that sets man above the rest of sensible beings, and gives him all the advantage and dominion which he has over them; it is certainly a subject, even for its nobleness, worth our labour to inquire into.

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.

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.
الصفحة 180 - 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.
الصفحة 137 - 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.
الصفحة 92 - The only reason for supposing such a connection in any instance is, that we have invariably found certain things to have been conjoined in fact ; and this experience, in many cases, produces a conviction equal to that of demonstration.
