G. K. Chesterton speaks about human origins in The Everlasting Man:
There may be a broken trail of stone and bone faintly suggesting the development of the human body. There is nothing even faintly suggesting such a development of this human mind. It was not and it was; we know not in what instant or in what infinity of years. Something happened; and it has all the appearance of a transaction outside time. It has therefore nothing to do with history in the ordinary sense. The historian must take it or something like it for granted; it is not his business as a historian to explain it.
…Even in trying to prove that religion grew slowly from rude or irrational sources, they begin their proof with the first men who were men. But their own proof only proves that the men who were already men were already mystics. They used the rude and irrational elements as only men and mystics can use them. We come back once more to the simple truth; that at some time too early for these critics to trace, a transition had occurred to which bones and stones cannot in their nature bear witness; and man became a living soul.
…With tombs like mountains of man set four-square and pointing to the stars; with winged and bearded bulls standing and staring enormous at the gates of temples; standing still eternally as if a stamp would shake the world. The dawn of history reveals a humanity already civilised. Perhaps it reveals a civilisation already old. And among other more important things, it reveals the folly of most of the generalisations about the previous and unknown period when it was really young. The two first human societies of which we have any reliable and detailed record are Babylon and Egypt. It so happens that these two vast and splendid achievements of the genius of the ancients bear witness against two of the commonest and crudest assumptions of the culture of the moderns. If we want to get rid of half the nonsense about nomads and cave-men and the old man of the forest, we need only look steadily at the two solid and stupendous facts called Egypt and Babylon.
…It has appeared to a good many intelligent and well-informed people quite as probable that the experience of the savages has been that of a decline from civilisation. Most of those who criticise this view do not seem to have any very clear notion of what a decline from civilisation would be like. Heaven help them, it is likely enough that they will soon find out.
…If there is one fact we really can prove, from the history that we really do know, it is that despotism can be a development, often a late development and very often indeed the end of societies that have been highly democratic. A despotism may almost be defined as a tired democracy. As fatigue falls on a community, the citizens are less inclined for that eternal vigilance which has truly been called the price of liberty; and they prefer to arm only one single sentinel to watch the city while they sleep.
…Our most ancient records only reach back to a time when humanity had long been human, and even long been civilised. The most ancient records we have not only mention but take for granted things like kings and priests and princes and assemblies of the people; they describe communities that are roughly recognisable as communities in our own sense.
