Well it's not that the quote is atrocious. There is undeniably a lot of truth in it. Many many people are like that.
Man is profoundly dependent on the reflection of himself in another man's soul, be it even the soul of an idiot.
― Witold Gombrowicz, Ferdydurke
The question is the context. You used it - or so it seemed to me in our own context - like it was a proper and inevitable truth (and therefore anyone judging and labeling you something is proof it is so).
But I wonder if he is actually working against you, lamenting the sad philosophical state of Man. Like the line after the quote would be . . .
and people really need to cut that shit out for their own good.
I would suspect that's the case. It is such a standard bit of philosophy. I have discussed it for decades in groups with thousands of people (of all levels of sociability), where we talk about what works and doesn't work towards happiness and peace.
What I have observed are results that are remarkably close to unanimous: best to work towards increased self-awareness and self-honesty and away from dependance on the opinions of others.
That quote is the enemy. A lot of people are there right now, no question. But people who have identified it as the enemy - and have been fighting it for as long as I have, really do progress away from it.
In other words, the mere fact that I am being judged from the outside is not going to sway me. A good argument might - but this is such a trivial arbitrary discussion about where lines are drawn on abstract concepts that I don't see anywhere else to go with it.
