I suggest you ask a question about what he actually said (wrote) if you want an answer. In the current form the question doesn't seem to be that (a question) at all but a cheap rhetorical method to pretend the other party said something ridiculous by taking a few words but adding exaggeration until the original contents no longer exists.

The only way to learn mathematics
is by doing exercises.
To this, gone35 replied:
This, in my experience, is utterly false.
To me, that says that it's not true that the only way to learn mathematics is by doing only exercises. Logically, that means there is some way to learn mathematics by doing something other than exercise, possibly in addition to exercise, admittedly, but certainly something that is not exercises.
The word "utterly" seems additionally to imply that this extra something completely outweighs the exercises, perhaps even to the point of no longer requiring exercises at all. And so my question.
So I believe my question to have been completely reasonable. Rephrasing gone35:
In my experience, is utterly false that
the only way to learn mathematics is by
doing exercises.
So let me be very much more specific.
gone35: I would be very interested to
know what methods of learning
mathematics you espouse other
than, or perhaps in addition
to, doing exercises.
Perhaps you are simply talking past each other? If "think through stuff" involved coming up with your own questions about the material and answering them, this would fall under what many mathematicians would call "exercise". In fact, I've found the belief that this is often more valuable than in-book excercises to be pretty pervasive in mathematics.
I think the original proposition is just a tautology. What does it mean to "know" something? I think it is equivalent to being able to complete an "exercise".
The fallacy here is thinking that the exercises in a book are special and must be completed and/or that you must have completed one before you could complete another outside the book.
This, in my experience, is utterly false.
It does seem to be a pervasive bias in the community, though --cf. the ubiquitous "[missing step] is left as an exercise to the reader", and so forth.
