“And be sure also, if the writer is worth anything, that you will not get at his meaning all at once; – nay, that at his whole meaning you will not for a long time arrive in any wise. Not that he does not say what he means, and in strong words too; but he cannot say it all; and what is more strange, will not, but in a hidden way and in parables, in order that he may be sure you want it. I cannot quite see the reason of this, nor analyze that cruel reticence in the breasts of wise men which makes them always hide their deeper thought. They do not give it you by way of help, but of reward; and will make themselves sure that you deserve it before they allow you to reach it. . . ."
(John Ruskin, Sesame and Lilies)
