"About the scientific revolution: it “outshines everything since the rise of Christianity and reduces the Renaissance and Reformation to the rank of mere episodes”."

“The study of the past with one eye upon the present is the source of all sins and sophistries in history. It is the essence of what we mean by the word "unhistorical.”

“When the sins and errors of an age have made the world impossible to live in, the next generation, seeking to make life tolerable again, may be able to find no way save by surrender of cherished ideals, and so may find themselves compelled to cast about for new dreams and purposes. An important aspect of the historical process is the work of the new generation... being driven to something like a creative act for the very reason that life on the old terms has become impossible.”

“The hardest strokes of heaven fall in history upon those who imagine that they can control things in a sovereign manner, as though they were kings of the earth, playing Providence not only for themselves but for the far future—reaching out into the future with the wrong kind of far-sightedness, and gambling on a lot of risky calculations in which there must never be a single mistake. And it is a defect in such enthusiasts that they seem unwilling to leave anything to Providence, unwilling even to leave the future flexible, as one must do; and they forget that in any case, for all we know, our successors may decide to switch ideals and look for a different utopia before any of our long shots have reached their objective, or any of our long-range projects have had fulfillment. It is agreeable to all the processes of history, therefore, that each of us should rather do the good that is straight under our noses. Those people work more wisely who seek to achieve good in their own small corner of the world and then leave the leaven to leaven the whole lump, than those who are for ever thinking that life is vain unless one can act through the central government, carry legislation, achieve political power and do big things.”

“If history can do anything it is to remind us of those complications that undermine our certainties, and to show us that all our judgements are merely relative to time and circumstance. ...we can never assert that history has proved any man right in the long run.”

“We have to be on our guard when the whig historian tells us... that the Reformation is justified because it ultimately led to liberty... for it is possible to argue against the whig historian that the ultimate issue which he applauds only came in the long run from the fact that, in its immediate results, The Reformation was disastrous to liberty.”

“But the greatest menace to our civilization today is the conflict between giant organized systems of self-righteousness—each system only too delighted to find that the other is wicked—each only too glad that the sins give it the pretext for still deeper hatred and animosity.”
