" I saw that morality varies from person to person, from group to group, from nation to nation.And the most interesting thing is that when I began to study history, I realised that morality changes with time. Morality will even shift to its exact opposite when the conditions that once produced it yield to change.When a new set of circumstances appears it is the people with a highly developed sense of individual freedom of choice that first try to change the status quo. More conservative individuals with a less developed sense of freedom resist change for as long as possiblebut give up in the end. Man always has freedom of choice, unlike other creatures, who only change their way of life when they are forced to by the natural environment.Now I understand that the morality which is said to be inherent in God, or, as the atheists prefer to express it, in Nature, naively thinking that replacing the word ‘God’ with ‘Nature’ will make them sound more scientifically convincing, does not exist at all!
