“Morality is part of man and it evolves over time just like the rest of humanity in accordance with Darwinian theory. If we said earlier that man’s evolution depends on change in the natural environment, now we must include the level of freedom of choice in that environment as a factor for change, for it is on this that the condition of morality depends.The higher the level of freedom of choice in society, the more liberal and humanistic that society’s morality will be.”
