> It's one thing to memorize arguments in favour of a position. It's another to actively defend your positions against those aggressively invested in proving you wrong. John Stuart Mill argued that only the latter activity produces the real understanding that allows an argument, or a tradition, to be renewed and kept alive across generations against constant attempts at refutation. If you are regurgitating a stance instead of actively fighting to defend one, do you really believe in what you are saying?

A person generally cannot effectively, fluently, convincingly regurgitate an argument without understanding it, and the act of memorizing a variety of different positions primes the brain to handle all of them with greater depth and adroitness. Mill greatly underestimates the power and benefits of memorization.

I think most people would agree that memorization and a standarized 'one-size-fits-all' approach are inferior to teaching methods that are (onstensibly) creative, 'active,' and individualized.

I couldn't disagree more strongly. It's a false dichotomy. All learning -- all -- starts from and depends upon memorization. Is that its only the goal? Obviously not, but memorization gets a bad rap because it's viewed, incorrectly, as contrary to or in competition with more active, creative intellectual enterprises.

I once heard a lecture by a (famous) college professor who talked about the large numbers of students who failed (college) Algebra 1.

His argument was: you cannot memorize algebra, you have to understand. Students who are failing in college do so because they do not understand the fundamentals, and try to memorize enough to succeed - not realizing that the effort needs to go somewhere else.

Rule 1 of memorization is "do not [memorize] if you do not understand". [1] (Note: that source uses the word "learn" instead of "memorize", but to me the word learn means come to understand.)

There is a role for memorization and rote repetition, but it is not the foundation of understanding.

Yeah, memorization is very underrated.

Memorization increases the size of the building blocks you can use.

Mathematics is where I see this most clearly. Why memorize hundreds of theorems? Because then you can just cite them on the fly when doing real mathematics. If you had to re-derive everything, you'd be stuck doing undergrad level math forever.

Chess Grand Masters have large repertoires of memorised openings. They do not play rote games with no understanding.

They run variations, twists and traps, on recalled openings and duel and fool by creating and breaking expectations.

In line with a number of other activities rote core skills and reflexes are foundational but not all, they're essential to practice and to dealing with situations where they don't fit but can be bent to purpose.

This is a good example because a test of one's understanding is "do you know how to make the opponent pay for varying from the standard opening?"

For a beginner, the answer is no.
