Excerpt from 1984 describing how our mathemagicians and politicians produced a dual system of astronomy using doublethink.
“ ‘But the world itself is only a speck of dust. And man is tiny — helpless! How long has he been in existence? For millions of years the earth was uninhabited.’
‘Nonsense. The earth is as old as we are, no older. How could it be older? Nothing exists except through human consciousness.’
‘But the rocks are full of the bones of extinct animas — mammoths and mastodons and enormous reptiles which lived here long before man was ever heard of.’
‘Have you ever seen those bones, Winston? Of course not. Nineteenth-century biologists invented them. Before man there was nothing. After man, if he could come to an end, there would be nothing. Outside man there is nothing.’
‘But the whole universe is outside us. Look at the stars! Some of them are a million light-years away. They are out of reach for ever.’
‘What are the stars?’ said O’Brien indifferently. ‘They are bits of fire a few kilometers away. We could reach them if we wanted to. Or we could blot them out. The earth is the centre of the universe. The sun and the stars go round it.’
Winston made another convulsive movement. This time he did not say anything. O’Brien continued as though answering a spoken objection:
‘For certain purposes, of course, that is not true. When we navigate the ocean, or when we predict an eclipse, we often find it convenient to assume that the earth goes round the sun and that the stars are millions upon millions of kilometers away. But what of it? Do you suppose it is beyond us to produce a dual system of astronomy? The stars can be near or distant, according as we need them. Do you suppose our mathematicians are unequal to that? Have you forgotten doublethink?’
Winston shrank back upon the bed. Whatever he said, the swift answer crushed him like a bludgeon. ”
You know this is allegory and there's no actual dual system of astronomy, right?
That's what you think.
