Laudator Temporis Acti

John Ruskin (1819-1900), Sesame and Lilies, rev. ed. (London: Smith, Elder & Co., 1871), pp. 32-33:

And by this process you will gradually come to attach less weight to your own "Thus I thought" at other times. You will begin to perceive that what you thought was a matter of no serious importance; — that your thoughts on any subject are not perhaps the clearest and wisest that could be arrived at thereupon: — in fact, that unless you are a very singular person, you cannot be said to have any "thoughts" at all; that you have no materials for them, in any serious matters;* — no right to "think," but only to try to learn more of the facts. Nay, most probably all your life (unless, as I said, you are a singular person) you will have no legitimate right to an "opinion" on any business, except that instantly under your hand. What must of necessity be done, you can always find out, beyond question, how to do. Have you a house to keep in order, a commodity to sell, a field to plough, a ditch to cleanse? There need be no two opinions about these proceedings; it is at your peril if you have not much more than an "opinion" on the way to manage such matters. And also, outside of your own business, there are one or two subjects on which you are bound to have but one opinion. That roguery and lying are objectionable, and are instantly to be flogged out of the way whenever discovered; — that covetousness and love of quarrelling are dangerous dispositions even in children, and deadly dispositions in men and nations; — that, in the end, the God of heaven and earth loves active, modest, and kind people, and hates idle, proud, greedy, and cruel ones; — on these general facts you are bound to have but one, and that a very strong, opinion. For the rest, respecting religions, governments, sciences, arts, you will find that, on the whole, you can know NOTHING, — judge nothing; that the best you can do, even though you may be a well-educated person, is to be silent, and strive to be wiser every day, and to understand a little more of the thoughts of others, which so soon as you try to do honestly, you will discover that the thoughts even of the wisest are very little more than pertinent questions.

* Modern "Education" for the most part signifies giving people the faculty of thinking wrong on every conceivable subject of importance to them.
