Childhood’s end

I read this very interesting novel by Arthur C Clarke (1953). In this novel, the Earth is visited by powerful aliens, the Overlords. These beings, however, turn out not to be conquerors or Lords of the Universe, simply babysitters. They know that life on earth will undergo a transformation, unavailable, for unknown reasons, to them. In the end, the last generations of humans develop telekinetic powers, cease requiring ordinary nutrition, and finally vanish in a translation to another existence, whose terms, as energy, spirit, or transcendence, are left obscure, even to the Overlords. This kind of apocalypse is not of a kind familiar from existing religions, but to the non-religious it probably would also seem unlikely, especially when we learn that the Overlords are directed by a being, the Overmind, whose purposes and nature are really unknown to them. Nevertheless, we must consider that, however unlikely such a development seems, we cannot anticipate what is liable to emerge in the universe with increasing levels of development and complexity. At each level of organization in nature, it would be difficult or impossible for us to predict what emerges at the next level.
Yet we persist, sitting in one of these statistical classes, I began thinking what if there was no order, there was no purpose, there was no grand hidden meaning, what if the outliers were telling us everything. As beauty is in the eye of the beholder, so is order for the scientist. This holds up rather well in general opinion, but the informed scientist must admit, even if grudgingly, that it doesn't quite agree with the results of science. There is, as it happens, a scientific measure of order. It is called "ENTROPY".
