The world is changing rapidly, and everyone changes along with the world. Discoveries is now becoming rampant; intellectually, technologically,etc, each having its advantage and disadvantage.
The publication in 1859 of the Origin of Species by Charles Darwin made a marked epoch in my own mental development, as it did in that of human thought generally. Its effect was to demolish a multitude of dogmatic barriers by a single stroke, and to arouse a spirit of rebellion against all ancient authorities whose positive and unauthenticated statements were contradicted by modern science.
Because of poverty and ignorance, not everyman living on earth lives in the same epoch!
