Leigh's Thesis: Appendix 1 (3)


Have you ever, in listening to a debate among adult and presumably responsible people, been fretted by the extraordinary inability of the average debater to speak to the question, or to meet and refute the arguments of speakers on the other side? Or have you ever pondered upon the extremely high incidence of irrelevant matter which crops up at committee meetings, and upon the very great rarity of persons capable of acting as chairmen of committees? And when you think of this, and think that most of our public affairs are settled by debates and committees, have you ever felt a certain sinking of the heart?

Have you ever followed a discussion in the newspapers or elsewhere and noticed how frequently writers fail to define the terms they use? Or how often, if one man does define his terms, another will assume in his reply that he was using the terms in precisely the opposite sense to that in which he has already defined them? Have you ever been faintly troubled by the amount of slipshod syntax going about? And, if so, are you troubled because it is inelegant or because it may lead to dangerous misunderstanding?

Do you ever find that young people, when they have left school, not only forget most of what they have learnt (that is only to be expected), but forget also, or betray that they have never really known, how to tackle a new subject for themselves? Are you often bothered by coming across grown-up men and women who seem unable to distinguish between a book that is sound, scholarly, and properly documented, and one that is, to any trained eye, very conspicuously none of these things? Or who cannot handle a library catalogue? Or who, when faced with a book of reference, betray a curious inability to extract from it the passages relevant to the particular question which interests them?

Do you often come across people for whom, all their lives, a “subject” remains a “subject,” divided by watertight bulkheads from all other “subjects,” so that they experience very great difficulty in making an immediate mental connection between let us say, algebra and detective fiction, sewage disposal and the price of salmon—or, more generally, between such spheres of knowledge as philosophy and economics, or chemistry and art?

Are you occasionally perturbed by the things written by adult men and women for adult men and women to read? We find a well-known biologist writing in a weekly paper to the effect that: “It is an argument against the existence of a Creator” (I think he put it more strongly; but since I have, most unfortunately, mislaid the reference, I will put his claim at its lowest)—“an argument against the existence of a Creator that the same kind of variations which are produced by natural selection can be produced at will by stock breeders.”

One might feel tempted to say that it is rather an argument for the existence of a Creator. Actually, of course, it is neither; all it proves is that the same material causes (recombination of the chromosomes, by crossbreeding, and so forth) are sufficient to account for all observed variations—just as the various combinations of the same dozen tones are materially sufficient to account for Beethoven’s Moonlight Sonata and the noise the cat makes by walking on the keys. But the cat’s performance neither proves nor disproves the existence of Beethoven; and all that is proved by the biologist’s argument is that he was unable to distinguish between a material and a final cause.
