History isn't like that. History unravels gently, like an old sweater. It has been patched and darned many times, reknitted to suit different people, shoved in a box under the sink of censorship to be cut up for the dusters of propaganda, yet it always - eventually - manages to spring back into its old familar shape. History has a habit of changing the people who think they are changing it. History always has a few tricks up its frayed sleeve. It's been around a long time.
Terry PratchettThe merest accident of microgeography had meant that the first man to hear the voice of Om, and who gave Om his view of humans, was a shepherd and not a goatherd. They have quite different ways of looking at the world, and the whole of history might have been different. For sheep are stupid, and have to be driven. But goats are intelligent, and need to be led.
