A vision of human progress where the social feeling becomes so developed that individuals naturally seek harmony with others rather than viewing fellow creatures as rivals for happiness.
Chapter IV: OF WHAT SORT OF PROOF THE PRINCIPLE OF UTILITY IS SUSCEPTIBLE.

The author posits that first principles and ultimate ends cannot be proven by traditional reasoning, but must instead be validated through an appeal to our internal consciousness and senses.

Mill proposes that the only proof that happiness is desirable is the empirical fact that people actually desire it, establishing it as the ultimate end of conduct.

Mill argues that utilitarianism views virtue not just as a means to an end, but as a psychological good that should be desired for its own sake to achieve a state of mind most conducive to general happiness.

The author explains that specific pleasures and virtues are not merely means to a collective happiness but are desired as constituent parts of happiness itself once they are loved for their own sake.
