Exercise 1: What Farkas Bolyai's Language Reveals — Possible Solution
==========================================================================

Ordinary fatherly caution would typically sound practical and forward-
looking - warnings about wasted time, career risk, or the difficulty of
the problem itself. Farkas's actual language does something very
different: it's intensely personal, emotional, and backward-looking,
describing his OWN past experience rather than offering practical advice
about János's future.

"I have traversed this bottomless night, which extinguished all light
and joy in my life" describes something closer to genuine despair than
ordinary professional disappointment. Calling the years he spent on the
problem a "bottomless night" that "extinguished all light and joy"
suggests the failed pursuit didn't just cost him time or professional
recognition - it seems to have taken a real, lasting emotional toll,
described in terms usually reserved for genuine personal suffering
rather than an unsolved math problem.

This suggests Farkas wasn't simply trying to redirect his son toward a
more "productive" use of his talents in the ordinary sense - he seems
to have been trying to protect János from something he experienced as
genuinely damaging to his own wellbeing, having lived through years of
fruitless obsession with the exact same unsolved problem himself. The
warning reads less like professional guidance and more like someone
trying to spare their own child from a real, personally costly
experience they themselves never fully recovered from.

ANSWER: Farkas's language is unusually personal and emotionally
intense rather than practically cautionary - describing his years on
the problem as a "bottomless night" that "extinguished all light and
joy" suggests real, lasting personal suffering, not just professional
frustration, implying he was trying to protect his son from a
genuinely damaging experience he had personally lived through himself,
not merely discouraging a career detour.

WHY THIS WORKS AS AN ANSWER
------------------------------
This reads Farkas's specific real language closely and identifies what
it reveals about the difference between ordinary caution and genuine,
lived emotional damage, rather than treating the warning as generic
parental advice.
