Michael McCullough describes science that helps us comprehend how revenge came to have a purpose in human life. At the same time, he stresses, science is also revealing that human beings are more instinctively equipped for forgiveness than we’ve perhaps given ourselves credit for. Knowing this suggests ways to calm the revenge instinct in ourselves and others and embolden the forgiveness intuition.
