According to your definition:
Although all pleasant activities are capable of self-justification, nothing that is painful may justify itself.
Beyond that though. Is the "self-fueling belief" in one's superiority (or any aspect, imagined or real) really justifiable outside the realm of the self? You may very well prove it to yourself, but how can you impose that task on another who cannot, practically, possess the tools to do so?
You are asking people to invent a belief in your superiority first. That is going to require some convincing from your part (payment, as you say) but you would be tricking them into investing onto something which cannot be inwardly proved. You would be selling them an illusion at best.
Unless we can safely argue that everything is an illusion, and if we are indeed to sell something, it might as well be a true truth (if that is ever possible). This should be any philosopher's ultimate humanly aim.
On a brighter note. Your theory could very much fly. Consider the creation of yet another cryptocurrency iteration, SupaSpecie (abbreviated SS, hereby patented and blockchained). If humans are so prone in bying into illusions, they will definitely want to use this one too!
Thank you for this brilliant opportunity for discource!
Yeah I was thinking of this idea of everyone having their own crypto coin while writing this!
The belief in one's own superiority is often tied to external outcomes by the individual himself. This is why artists struggle instead of feeling indifferent toward people's indifference. The reason is because, if you believe you're objectively right, then there's an objective "ought to" hiding in your belief. To be more concrete, the person who believes in his own let's say artistic superiority cannot, I think, believe in the following two statements at the same time: (a) I am a superior artist to person X (b) X ought to have greater artistic success than I, all things being equal. I think there's a contradiction hiding there somewhere, though there's no immediately evident logical fallacy there, and I think in this and similar ways our subjective beliefs get tied to the external world, and we begin to attempt and to struggle to externalize our inner convictions.
Thanks for the comment!
