Nothing is inherently and invincibly young except spirit. And spirit can enter a human being perhaps better in the quiet of old age and dwell there more undisturbed than in the turmoil of adventure.
George SantayanaTo fight is a radical instinct; if men have nothing else to fight over they will fight over words, fancies, or women, or they will fight because they dislike each other's looks, or because they have met walking in opposite directions.
George Santayana
