I do not know what I may appear to the world; but to myself I seem to have been only like a boy playing on the seashore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me.
我不知道世人怎样看待我，但是在我看来，我不过是一个在海滩上玩耍的小孩，不时地为发现一块更光滑的鹅卵石或更漂亮的贝壳而沾沾自喜，然而真理的海洋仍然在我面前，有待去发现。
