Il n’est rien de plus tragique que de voir quelqu’un enlisé dans la longueur d’une vie dépourvue de largeur.

Martin Luther King Jr. – Les trois dimensions d’une vie complète (1954)

[« We must not stop here. It’s dangerous to stop with the length of life. Some people never get beyond this first dimension of life, they’re often brilliant people. They develop their inner powers. They do extraordinarily well in their fields of endeavor. They live life as if nobody else lived in the world but themselves. Other people become mere means by which they climb to their personal ends or their personal ambitions. Their love is only a utilitarian love. There is nothing more tragic in life to find an individual bogged down in the length of life, devoid of the breadth. »]
