That’s a fair challenge, and I think we may actually be closer than it first sounds.
I’m not treating “understanding” as some private internal state that the app can directly verify, and I definitely don’t have a physiological verification algorithm.
What I’m trying to do is use observable behavior as a proxy for understanding: can you explain the idea in your own words, defend a position, respond to objections, stay logically consistent, and adapt your reasoning when the argument changes?
So when I say the app helps someone “understand” philosophy, I really mean that it gives them a way to test whether they can actually do something with the idea rather than just recognize or repeat it.
I’d be curious where you think that methodology still falls short. If understanding is exhausted by observable behavior, what behavioral criteria would you consider strongest for demonstrating that someone has genuinely learned a philosophical idea?
I think this helps clarify where we’re using “understanding” differently.
I’m not claiming the app can measure whether an idea has been fully embodied, changed someone’s physiology, or altered how they behave in the real world. That would be a much stronger claim than what I’m trying to make.
What I’m trying to measure is narrower: whether someone can move beyond passive recognition of an idea and demonstrate conceptual and argumentative competence with it. Can they explain their position, respond to objections, recognize contradictions, revise an argument, and apply the idea to a new question?
I agree that none of that proves the idea has been incorporated into their behavior or produced some lasting transformation outside the debate.
Where I’m less convinced is that physiological measures like heart rate or ATP expenditure would solve that problem. A lower heart rate under stress could reflect many things unrelated to philosophical understanding, and physical action alone wouldn’t tell us whether someone understood the idea that supposedly motivated it.
So I’d probably distinguish three levels: understanding an idea conceptually, being able to reason with it, and actually embodying or acting on it. The Agora is mainly trying to help with the first two, not claim that it can verify the third.
That said, the third level is interesting. What real-world behavioral outcome would you consider a convincing test of someone having assimilated a philosophical idea, while still being able to distinguish that from unrelated changes in behavior?
I think this is probably where our disagreement becomes more fundamental.
I understand the materialist point you’re making, but I’m not sure I see how mass, density, or the physical transformation of matter gives us a usable criterion for distinguishing understanding from non-understanding.
Two people can have essentially the same physical capabilities while one can recognize contradictions in an argument, apply a concept to a novel situation, defend it against objections, and explain its implications while the other cannot. Those differences seem meaningful to me even if, ultimately, both processes are physically instantiated.
I’m also hesitant about the word “exclusively.” Even if understanding necessarily has a material substrate, it doesn’t follow that rheological properties are the only level at which it can meaningfully be evaluated.
So I think my question would be very concrete: if I gave two people the same philosophical text, what measurable experiment would your methodology use to determine that one genuinely understood it and the other did not?
I’m genuinely curious what that test would look like in practice.
