Individual and Collective Flourishing in Kant's Philosophy

In ‘Happiness and Human Flourishing’, Thomas E. Hill, Jr, contrasts Kant's notion of happiness with that of human flourishing, explains the role of happiness in Kant's ethics, and suggests some reasons why Kant portrays happiness rather than flourishing as the non-moral good of the individual. While there is much I agree with in Hill's essay, I disagree with Hill on how best to conceive of human flourishing in Kant's philosophy, and on the importance of human flourishing in Kant's ethics. Comparing my views with Hill's is not what chiefly interests me, however. After section 1, I make little explicit reference to ‘Happiness and Human Flourishing’. Instead, I seek to expand the discussion begun there by Hill of ‘how happiness and human flourishing are relevant to [Kantian] ethics’
