In egalitarian societies, genes matter more. - Matt Ridley

Progress and success are always relative. When the land was unoccupied by animals, the first amphibian to emerge from the sea could get away with being slow, lumbering, and fish-like, for it had no enemies and no competitors. But if a fish were to take to the land today, it would be gobbled up by a passing fox as surely as a Mongol horde would be wiped out by machine guns. In history and in evolution, progress is always a futile, Sisyphean struggle to stay in the same relative place by getting ever better at things.

the Australian economist Peter Saunders argues, ‘Nobody planned the global capitalist system, nobody runs it, and nobody really comprehends it. This particularly offends intellectuals, for capitalism renders them redundant. It gets on perfectly well without them.

No study of the causes of intelligence has failed to find a substantial heritability.
