Understanding of ethics also evolves — not in a straight line, not without periods of regression, but it does evolve. Here on Earth we are feeling our way towards an ethic of mutual respect. Mutual respect is implied by a belief in equality, but, of far more consequence, it can be shown to follow from observation within material existence. That gives it a universal impetus that no belief can match. If interested, an brief introduction is available in “From Locke to Real Justice” here on medium.com.
