“And yet, Blaine thought, mankind showed an historic ability to avoid the extremes of doom as well as the extremes of bliss. Chaos was forever prophesized and utopia was continually predicted, and neither came to pass.”

Context: For our chronically and extremely hungry man, Utopia can be defined simply as a place where there is plenty of food. He tends to think that, if only he is guaranteed food for the rest of his life, he will be perfectly happy and will never want anything more. Life itself tends to be defined in terms of eating. Freedom, love, community feeling, respect, philosophy, may all be waved aside as fripperies that are useless since they fail to fill the stomach. Such a man may fairly be said to live by bread alone. It cannot possibly be denied that such things are true, but their generality can be denied. Emergency conditions are, almost by definition, rare in the normally functioning peaceful society.

Variant: History books that contain no lies are extremely dull.

Variant: We, true to our traditions, avoided all extremes, have steered clear of fascism, communism, dictatorship, and have shown the world that democratic government, constitutional methods and ordered liberty are not inconsistent with progress and prosperity.

Context: True to our traditions, we have avoided all extremes. We have steered clear of fascism, communism, dictatorship, and we have shown the world that democratic government, constitutional methods and ordered liberty are not inconsistent with progress and prosperity.

Context: To call out for the hand of the enemy is a rather extreme measure, yet a better one, I think, than to remain in continual fever over an accident that has no remedy. But since all the precautions that a man can take are full of uneasiness and uncertainty, it is better to prepare with fine assurance for the worst that can happen, and derive some consolation from the fact that we are not sure that it will happen.

Context: p>I have attempted to show that the geological record is extremely imperfect; that only a small portion of the globe has been geologically explored with care; that only certain classes of organic beings have been largely preserved in a fossil state; that the number both of specimens and of species, preserved in our museums, is absolutely as nothing compared with the incalculable number of generations which must have passed away even during a single formation; that, owing to subsidence being necessary for the accumulation of fossiliferous deposits thick enough to resist future degradation, enormous intervals of time have elapsed between the successive formations; that there has probably been more extinction during the periods of subsidence, and more variation during the periods of elevation, and during the latter the record will have been least perfectly kept; that each single formation has not been continuously deposited; that the duration of each formation is, perhaps, short compared with the average duration of specific forms; that migration has played an important part in the first appearance of new forms in any one area and formation; that widely ranging species are those which have varied most, and have oftenest given rise to new species; and that varieties have at first often been local (emphasis not Darwin's). All these causes taken conjointly, must have tended to make the geological record extremely imperfect, and will to a large extent explain why we do not find interminable varieties, connecting together all the extinct and existing forms of life by the finest graduated steps. He who rejects these views on the nature of the geological record, will rightly reject my whole theory. For he may ask in vain where are the numberless transitional links which must formerly have connected the closely allied or representative species, found in the several stages of the same great formation. He may disbelieve in the enormous intervals of time which have elapsed between our consecutive formations; he may overlook how important a part migration must have played, when the formations of any one great region alone, as that of Europe, are considered; he may urge the apparent, but often falsely apparent, sudden coming in of whole groups of species. He may ask where are the remains of those infinitely numerous organisms which must have existed long before the first bed of the Silurian system was deposited: I can answer this latter question only hypothetically, by saying that as far as we can see, where our oceans now extend they have for an enormous period extended, and where our oscillating continents now stand they have stood ever since the Silurian epoch; but that long before that period, the world may have presented a wholly different aspect; and that the older continents, formed of formations older than any known to us, may now all be in a metamorphosed condition, or may lie buried under the ocean.</p
