In “The Prophylaxis of Insanity” by Mary Putnam Jacobi (originally published in 1881), she critiques education. The critique comes within a discussion of people who don’t learn well, which is, according to her, a major cause of insanity.
In minds predisposed to insanity there is often, perhaps always, a marked deficiency of elasticity. An impression sinks and remains; the mind cannot disengage itself or recover its tone; it cannot pass quickly enough into the contrasting mood… This capacity should, therefore, be carefully cultivated by encouraging alternations of attention at the first sign of fatigue. The contrary practice of forcing an immature mind to continued attention while under the influence of fatigue, instead of teaching it how to quickly change, is the habit of commonplace education. Injurious to all, it is especially so to persons predisposed of depressing forms of insanity. It exhausts still further the elasticity in which they are naturally deficient. (193)

So when our students are tired of one topic, we should lead them to another… Which is what people now say we have to do because our students have such short attention spans. For them, this is not considered a positive. I wonder if people like Jacobi influenced our present culture.
