And so if any one would suppose that Æther (like our Air) may contain Particles which endeavour to recede from one another (for I do not know what this Æther is) and that its Particles are exceedingly smaller than those of Air, or even than those of Light: The exceeding smallness of its Particles may contribute to the greatness of the force by which those Particles may recede from one another, and thereby make that Medium exceedingly more rare and elastick than Air, and by consequence exceedingly less able to resist the motions of projectiles, and exceedingly more able to press upon gross Bodies, by endeavouring to expand it self.

I expect that mathematicians have classified such fuzzy logics. Certainly they have been much used by physicists. But is there not something to be said for the approach of Euclid? Even now that we know that Euclidean geometry is (in some sense) not quite true? Is it not good to know what follows from what, even if it is not necessarily FAPP? Suppose for example that quantum mechanics were found to resist precise formulation. Suppose that when formulation beyond FAPP was attempted, we find an unmovable finger obstinately pointing outside the subject, to the mind of the observer, to the Hindu scriptures, to God, or even only Gravitation? Would that not be very, very interesting?
John Stewart Bell
These things, which we state lightly enough here, are yet of deep import, and indicate a mighty change in our whole manner of existence. For the same habit regulates not our modes of action alone, but our modes of thought and feeling. Men are grown mechanical in head and in heart, as well as in hand. They have lost faith in individual endeavour, and in natural force, of any kind. Not for internal perfection, but for external combinations and arrangements, for institutions, constitutions, for Mechanism of one sort or other, do they hope and struggle. Their whole efforts, attachments, opinions, turn on mechanism, and are of a mechanical character.
Thomas Carlyle
What is the explanation of this evil reputation which attaches not to politicians of one party, but to the whole race? Primarily, I suppose, it is due to the fact that ever since States began to be they have been in peril and have trusted to force for their safety. War has been their normal history...With war and the preparation for war go the stratagems of diplomacy, the dropping of the ordinary code of morals, a holiday for truth, and an aftermath of cynicism...In the arena of international rivalry and conflict men have placed patriotism above truthfulness as the indispensable virtue of statesmen.
Stanley Baldwin
In America, the President reigns for four years, and journalism governs for ever and ever. Fortunately, in America journalism has carried its authority to the grossest and most brutal extreme. As a natural consequence it has begun to create a spirit of revolt, people are amused by it, or disgusted by it, according to their temperaments. but it is no longer the real force it was. It is not seriously treated. In England, journalism, except in a few well-known instances, not having been carried to such excesses of brutality, is still a great factor, a remarkable power. The tyranny that it proposes to exercise over people's private lives seems to me to be quite extraordinary.
Oscar Wilde
The sky is the 'source of light' in nature, and governs every thing. Even our common observations on the weather of every day, are suggested by them, but it does not occur to us. Their difficulty in painting both as to composition and execution is very great, because, with all their brilliancy and consequence, they ought not to come forward, or be hardly thought about in a picture... I know very well what I am about, and that my skies have not been neglected, though they have often failed in execution, no doubt, from an over-anxiety about them, which will alone destroy that easy appearance which nature always has in all her movements.
John Constable
