To-day I have scrapped somebody's Rural Arithmetic. It is full of sums of the How-much-will-it-take-to-paper a-room? type. This cursed utilitarianism in education riles me. Who wants to know what it will take to paper a room? Personally I should call in the painter, and take my meals on the parlour piano for a day or two. Anyway, why this suspicion of the poor painter? Is he worse than other tradesmen? If we must have a utilitarian arithmetic then I want to see a book that will tell me if the watchmaker is a liar when he tells me that the mainspring of my watch is broken. I want to see sums like this:--How long will a plumber take to lay a ten foot pipe if father can do it at the rate of a yard in three minutes? (Ans., three days). To me Arithmetic is an art not a science. I do not know a single rule; I must always go back to first principles. I love catch questions, questions that will make a bairn think all the time. Inspectors' Tests give but little scope for the Art of Arithmetic; they are usually poor peddling things that smell strongly of materialism. In other words, they appeal to the mechanical part of a bairn's brain instead of to the imagination. I want to see a test that will include a sum like this:--23.4 × .065 × 54.678 × 0. The cram will start in to multiply out; the imaginative bairn will glance along and see the nought, and will at once spot that the answer is zero. * * * I have just discovered an excellent song-book--Curwen's _Approved Songs_. It includes all the lovely songs of Cavalier and Puritan times, tunes like _Polly Oliver_ and _Golden Slumbers_. At present my bairns are singing a Christmas Carol by Bridge, _Sweeter than Songs of Summer_. They sing treble, alto, and tenor, while I supply the bass. The time is long past Christmas, but details like that don't worry me. This carol is the sweetest piece of harmonising I have heard for a long time. * * * I have been re-reading Shaw's remarks on Sex in Education. I cannot see that he has anything very illuminating to say on the subject; for that matter no one has. Most of us realise that something is wrong with our views on sex. The present attitude of education is to ignore sex, and the result is that sex remains a conspiracy of silence. The ideal some of us have is to raise sex to its proper position as a wondrous beautiful thing. To-day we try to convey to bairns that birth is a disgrace to humanity. The problem before me comes to this: How can I bring my bairns to take a rational elemental view of sex instead of a conventional hypocritical one? How can I convey to them the realisation that our virtue is mostly cowardice, that our sex morality is founded on mere respectability? (It is the easiest thing in the world to be virtuous in Padanarum; it is not so easy to be a saint in Oxford Street. Not because Oxford Street has more temptation, but because nobody knows you there.)
