Think about where the world was just a century ago. The Wright brothers had just begun experimenting with the principles of flight. There were only a handful of democracies in the world. And women universally were denied the right to vote.
But something else was happening too. Mary Baker Eddy's book Science and Health with Key to the Scriptures had been published and was being circulated by a grass-roots movement of its readers. Growing numbers of thinkers around the world were pondering passages like this one from her chapter "Science of Being": "Belief in a material basis, from which may be deduced all rationality, is slowly yielding to the idea of a metaphysical basis, looking away from matter to Mind as the cause of every effect. Materialistic hypotheses challenge metaphysics to meet in final combat. In this revolutionary period, like the shepherd-boy with his sling, woman goes forth to battle with Goliath." Science and Health, p. 268.
