Full Idea
Kant grossly inflated the importance of the human dimension of value in which moral considerations are indeed overriding. He unjustifiably denied the perfectly reasonable contributions of the cultural and personal dimensions to human well-being.
Gist of Idea
Kant focuses exclusively on human values, and neglects cultural and personal values

A Reaction
Excellent to see someone talking about the ultimate values that reside behind Kant's theory. Without such assumptions his theory is, frankly, ridiculous (as Mill explained).
