First, thanks for an intelligent, thoughtful article.
One problem in individualism is that it has been based on Locke's "State of Nature," in which the ideal of human existence is presented as being that of a single, isolated individual. That is hardly a promising premise from which to approach the governance of "the collective of society." (Hobbes also had a "State of Nature" in his philosophy, but for him it most definitely did not represent the ideal state of human existence.)
It seems to me that the ideal lies between Lockean individualism and collectivism. It is individualism in an other-directed form, rather than self-centered.
