“Mankind are always happier for having been happy; so that if you make them happy now, you make them happy twenty years hence by the memory of it. A childhood past with a due mixture of rational indulgence, under fond and wise parents, diffuses over the whole of life, a feeling of calm pleasure; and, in extreme old age, is the very last remembrance which time can erase from the mind of man.”
