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? For in all these Hypotheses the Phaenomena of Light have been hitherto explain'd by supposing that they arise from new Modifications of the Rays; which is an erroneous Supposition.
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.
To me, it appears no unjust simile to compare the affairs of this great Continent to the mechanism of a clock, each state representing some one or other of the smaller parts of it which they are endeavoring to put in fine order without considering how useless & unavailing their labor is unless the great Wheel or Spring which is to set the whole in motion is also well attended to & kept in good order.
It is impossible, I say, for the human mind not to believe that there is in all this design, cause, and effect up to an Ultimate Cause-a Fabricator of all things, from matter and motion-their Preserver and Regulator while permitted to exist in their present forms-and their Regenerator into new and other forms.
Do you see this egg? With this you can topple every theological theory, every church or temple in the world. What is it, this egg, before the seed is introduced into it? An insentient mass. And after the seed has been introduced to into it? What is it then? An insentient mass. For what is the seed itself other than a crude and inanimate fluid? How is this mass to make a transition to a different structure, to sentience, to life? Through heat. And what will produce that heat in it? Motion.
For example: (1) As if governed by Newton's First Law of Motion, an institution will resist any change in its current direction; (2) Just as work expands to fill available time, corporate projects or acquisitions will materialize to soak up available funds; (3) Any business craving of the leader, however foolish, will be quickly supported by detailed rate-of-return and strategic studies prepared by his troops; and (4) The behavior of peer companies, whether they are expanding, acquiring, setting executive compensation or whatever, will be mindlessly imitated.
We cannot overstate our debt to the Past, but the moment has the supreme claim. The Past is for us; but the sole terms on which it can become ours are its subordination to the Present. Only an inventor knows how to borrow, and every man is or should be an inventor. We must not tamper with the organic motion of the soul.
I can well appreciate, Holy Father, that as soon as certain people realise that in these books which I have written about the Revolutions of the spheres of the universe I attribute certain motions to the globe of the Earth, they will at once clamour for me to be hooted off the stage with such an opinion.
My favorite writers have been those who've said things well. I used to study Eudora Welty. She has the remarkable ability to give you atmosphere, character, and motion in a single line. In one line! You must study these things to be a good writer. Welty would have a woman simply come into a room and look around. In one sweep she gave you the feel of the room, the sense of the woman's character, and the action itself. All in twenty words. And you say, How'd she do that? What adjective? What verb? What noun? How did she select them and put them together? I was an intense student.
