Is there any difference in principle between the kind of moral reasoning and the kind of disagreements that arise when we debate about justice and the meaning of free speech and the nature of religious liberty?
The cycle continues as long as the disagreement is about the facts but if instead of arguing the facts, you share your values and your real concerns, you're likely to have more success.
The instinct to co-operate wherever and whenever possible is deep within us, even in the most fractious times when disagreements are polished, paraded and asserted.
