The Power of Prediction

Quotes from DARKNESS AND LIGHT by Olaf Stapledon. 

This science fiction book was written in 1942. In his prologue, Stapledon is careful to announce that he is not writing prophecy, merely a fable of one possible future or, in this case, two. That was a wise caveat to add.

From Chapter 2, the Modern Age:

In the new world, made one by trains, ships, aeroplanes and radio there was room for one society only. But a world-wide society must inevitably be planned and organized in every detail. Not otherwise can freedom and fulfilment be secured for all individuals. 

From Chapter 3 Mankind at the Crossroads:

[…]
Not till the remnant of the British forces had been driven into Scotland, and were desperately holding a line roughly equivalent to the Roman Wall, did the American power begin to make itself felt, and then only for a while; for in America, as elsewhere, the old order was failing, its leaders had neither the imagination nor the courage to adjust themselves to the new world-conditions. Consequently, when at last their turn came they were quite incapable of organizing their haphazard capitalism for war (emphasis added).

The American people began to realize that they were the victims of incompetence and treachery, and the population of the Atlantic seaboard demanded a new regime. In this state of affairs resistance became impossible. Britain was abandoned, and North America reverted to a precarious isolationism knowing that the struggle would very soon begin again.

[…]

The Russians, whose initial revolutionary passion had long since been corrupted by the constant danger of attack and a consequent reversion to nationalism, now sacrificed all their hard-won social achievements (emphasis added) for a desperate defence against the attempt of the German ruling class to dominate the planet.

[…]

Contraception had produced not only a decline of population but also a tendency of the more intelligent strains in the population to breed less than the dullards and half-wits.

[…]

In spite of the grave perversion of the original generous revolutionary impulse, so much of solid worth had been achieved that the Soviet system of states was never in serious danger of disintegration (emphasis added).

[…]

Thus in India, when freedom had at last been gained, and under the stress of external danger Hindus and Mohammedans had sunk their differences, it seemed for a while that out of these dark Aryan peoples the truth was coming which could save mankind.

 

I would say that some of his comments current to the time in which he lived show as little accuracy: 
 

The Hammer and Sickle, formerly the most heartening emblem of the will for the light, but now sadly debased, was displayed on the Capitol.

[…]

The first Russian revolution, under Lenin, had been mainly a groping but sincere expression of the will for true community, and also an act of vengeance against a cruel and inefficient master class. When the leaders of the Revolution had established their power, they proceeded to remake the whole economy of Russia for the benefit of the workers. Foreign hostility, however, forced them to sacrifice much to military necessity.
