请帮忙翻译一下这段话,谢谢If the great Newton said that he seemed to have been all his life gathering a few shells on the shore, whilst a boundless ocean of truth still lay beyond and unknown to him, how much more to each of us must the sea of literature be a pathless immensity beyond our powers of vision or of reach−−an immensity in which industry itself is useless without judgment, method, discipline; where it is of infinite importance what we can learn and remember, and of utterly no importance what we may have once looked at or heard of. Alas! the most of our reading leaves as little mark even in our own education as the foam that gathers round the keel of a passing boat!
