A person is what relates to inner and outer powers; that is to say: can be them present or absent.
Identity, for example, you can have either in an absence or in a presence.
And if you have your identity in an absence, you can very well say, that you are a result of a line of challenges and reactions.
But the thought about challenge and reaction is, for the Idler, much more composite, and has a communicative character. You are not only challenged within a certain area, but from life as a wholeness.
And what you are is due to the way in which you relate to yourself.
