David Brooks writes:
People are “open wholes.” They find their perfection in communion with other whole persons. The crucial questions in life are not “what” questions — what do I do? They are “who” questions — who do I follow, who do I serve, who do I love? The reason for life, Jacques Maritain wrote, is “self-mastery for the purpose of self-giving.” It’s to give yourself as a gift to people and causes you love and to receive such gifts for others… Through this love, people touch the full personhood in others and purify the full personhood in themselves.
