I am not a psychologist in the modern technical sense of the term. I have no training in matters dealing with the brain or nervous system, and I possess only a rudimentary knowledge of human biochemistry. But I do love uncovering the etymologies of words, and therefore I can say that I aim to be a psychologist in the original sense of the Greek word psyche: the animating principle of the whole person, which we translate as “soul.” Saint Gregory the Great emphatically declares, in his influential “Pastoral Rule,” that the proper nurturing, challenging, and encouraging of souls is the great duty of priests, since “the care of souls is the art of arts.”
