Persius has justly observed, that knowledge is nothing to him who is not known by others to possess it: to the scholar himself it is nothing with respect either to honour or advantage, for the world cannot reward those qualities which are concealed from it; with respect to others it is nothing, because it affords no help to ignorance or errour.
Samuel JohnsonThe mere power of saving what is already in our hands must be of easy acquisition to every mind; and as the example of Lord Bacon may show that the highest intellect cannot safely neglect it, a thousand instances every day prove that the humblest may practise it with success.
