Empathy is like a universal solvent. Any problem immersed in empathy becomes soluble. It is effective as a way of anticipating and resolving interpersonal problems, whether this is a marital conflict, an international conflict, a problem at work, difficulties in a friendship, political deadlocks, a family dispute, or a problem with a neighbor.

If we treat another person as essentially bad, we dehumanize him or her. If we take the view that every human being has some good in them, even if it is only 0.1 percent of their makeup, then by focusing on their good part, we humanize them. By acknowledging and attending to and rewarding their good part, we allow it to grow, like a small flower in a desert.
