We must make a distinction between individuality and individualism. Man manifests his individuality when he fully develops his personality and talents by which he is different from others. At the same time, individuality encourages man to develop his intensely social character by participating in life together in community, acknowledging a moral law, and promoting the common good. The more specific, richer, and stronger this personal life, the more intense the social life. Thus, individuality results in stronger community.
Individualism is a deformation of individuality by which man makes himself the center of an enclosed world of personal self-interest that tends to disregard the social character of man and his role in community. (Taken from Return to Order, p. 74)
