"If a just society requires a strong sense of community, it must find a way to cultivate in citizens a concern for the whole, a dedication to the common good, It can't be indifferent to the attitudes and dispositions, the "habits of the heart," that citizens bring to public life. It must find a way to lean against purely privatized notions of the good life, and cultivate civic virtue."
~ Harvard Prof. Michael J. Sandel
In other words, we're all in this together,
so do unto others as you would have them do unto you.
