Thus it appears, that the definitions of mathematics destroy the pretended demonstrations; and that if we have the idea of indivisible points, lines and surfaces conformable to the definition, their existence is certainly possible: but if we have no such idea, it is impossible we can ever conceive the termination of any figure; without which conception there can be no geometrical demonstration. We may also observe in this instance of sounds and colours, that we can attribute a distinct continued existence to objects without ever consulting REASON, or weighing our opinions by any philosophical principles. Wow. Now, how it is possible that out of a given state one quite opposite to it in the same thing should follow, reason without an example can not only not conceive, but cannot even make intelligible without intuition; and this intuition is the motion of a point in space; the existence of which in different spaces (as a consequence of opposite determinations) alone makes the intuition of change possible. Reason can never satisfy us that the existence of any one object does ever imply that of another; so that when we pass from the impression of one to the idea or belief of another, we are not determined by reason, but by custom or a principle of association. After this any one will understand how we may form the idea of an impression and of an idea, and how we way believe the existence of an impression and of an idea. Secondly, There is a false sensation or experience even of the liberty of indifference; which is regarded as an argument for its real existence. [*Footnote; The "I think" expresses the act of determining my own existence. [*Footnote; We can easily conceive the non-existence of matter; but the ancients did not thence infer its contingency.
