No. It is bizarre to suggest pragmaticality is the reason for morality. Where did this come from? How does it even answer the question pragmatically? Please address my points logically. I have previously stated that a moral code in a group of humans allows that group to succeed in competition with a morally bereft group. Is this not true?
Next, please address how morality is not pragmatic.
Third, please address what you think pragmaticism actually is, if it isn't being practical.
To say that pragmaticality is the reason for morality is like saying dark is the reason for light. One is merely the shadow of the other. Pragmaticality says nothing of moral good and bad unless morality is just dictated by man and his surroundings and there is not really good or bad.
