That sounds pretty self-conscious and fake, like a teenager trying to dress like a nonconformist. Altered states of consciousness do exist, and extreme isolation is known to produce them.
But my point is that that's not necessarily what the hermit was doing. I don't think he was reacting against the idea of defining himself. I think he was experiencing the effects of extreme isolation, and trying to describe afterwards what it felt like.
Except he defined himself as someone who doesn't need to define himself.
One can never be free from definitions.
