Funny, in the sense that having a lack of commentary is itself an answer.
Not having read the book almost invites opining on the state of education now. That may not be fair as I suspect Russell was addressing more specific topics from back then, plus pushing the parochial breaking effect of the English educational system as seen by the people living then.
Russell spans a critical gap of time in human history, stretching back into the nineteen century. By the educational standards of earlier times what we have done is near miraculous. We have achieved almost universal literacy, basic numeracy, and simple arithmetic aptitude. We may hand almost anyone a bible and expect them to read it out loud, follow a bus or train schedule to get to work, do data entry and scheduling, insert tab A into tab B and tighten with measured tool C – all without someone else standing over the shoulder to provide gesturing guidance. Yes, they would be amazed.
Unfortunately, what education is needed now is farther removed from these basics, and delves ever more deeply into the abstract. What we get are never ending drives to install values that were wearing thin in the nineteenth century itself, and prison daycare centers.
Just another obstacle to be overcome.
If this book and Russell's opinions are still relevant today then Carl Sagan's are far more so. And Gore Vidal. And many others … pic especially related.
Sorry this is tangential to the specific topic, OP. Blame my teachers.
