We have arranged for ourselves a world in which we can live - by positing bodies, lines, planes, causes and effects, motion and rest, form and content; without these articles of faith nobody could now endure life. But that does not prove them. Life is no argument. The conditions of life might include error.
"Thus, my friends," said Barbicane, "all motion suddenly stopped produces heat. And this theory allows us to infer that the heat of the solar disc is fed by a hail of meteors falling incessantly on its surface. They have even calculated - " "Oh, dear !" murmured Michel, "the figures are coming."
I had always hoped that the younger generation receiving their early impressions after the ﬂame of liberty had been kindled in every breast, & had become as it were the vital spirit of every American, that the generous temperament of youth, analogous to the motion of their blood, and above the suggestions of avarice, would have sympathized with oppression wherever found, and proved their love of liberty beyond their own share of it.
Rational mechanics must be the science of the motions which result from any forces, and of the forces which are required for any motions, accurately propounded and demonstrated. For many things induce me to suspect, that all natural phenomena may depend upon some forces by which the particles of bodies are either drawn towards each other, and cohere, or repel and recede from each other: and these forces being hitherto unknown, philosophers have pursued their researches in vain. And I hope that the principles expounded in this work will afford some light, either to this mode of philosophizing, or to some mode which is more true.
Are not all Hypotheses erroneous, in which Light is supposed to consist in Pression or Motion, propagated through a fluid Medium?

The poet presents the imagination with images from life and human characters and situations, sets them all in motion and leaves it to the beholder to let these images take his thoughts as far as his mental powers will permit. This is why he is able to engage men of the most differing capabilities, indeed fools and sages together. The philosopher, on the other hand, presents not life itself but the finished thoughts which he has abstracted from it and then demands that the reader should think precisely as, and precisely as far as, he himself thinks. That is why his public is so small.
