> Why would reading 1000 words of a great philosopher be any different from reading 1000 words of smut online

Agree that we should work on reducing the stigma around reading (which, incidentally, feels ridiculous to type); but very clearly one of these exercises your mind and one doesn't. People should want to learn things!

That's mostly a value judgement though.

What about fiction vs non-fiction? Travel vs escapism? This is hugely subjective, and very personal. What one person finds educational could be a navel gazing time wasting pursuit to someone else.
