To myself I am only a child playing on the beach while vast oceans of truth lie undiscovered before me.
If I have done the public any service it is due to my patient thought.
I was like a boy playing on the sea-shore and diverting myself now and then finding a smoother pebble or a prettier shell than ordinary whilst the great ocean of truth lay all undiscovered before me.
Errors are not in the art but in the artificers.
Tact is the art of making a point without making an enemy.
