Commenting in part to John Rawls' theory: https://aeon.co/videos/want-to-build-a-just-society-john-rawls-said-to-start-by-ignoring-your-identity
I suggested in my cultural theory class last week that it's possible to have a more fair society if people were more altruistic, my instructor responded with the fact that everyone has a personal identity narrative where being altruistic only contributes to a positive narrative for their identity. So therefore everyone is corruptible. When I suggested that it's harder to be corrupted if you lack a sense of identity, she said that that is silly - everybody has a sense of identity.
Well, I don't. I never had a sense of identity. Having Borderline Personality Disorder means (among other things) that my identity is fragmented: I don't know who I am. I never have. I don't really have a sense of Self, which makes me a great social chameleon (adapting to hegemonic social attitudes/behaviours of others), but also a decent objective perspective when necessary.
I only know that I am a Transhumanist, and so being a Transhumanist, I have the responsibility (though, not the obligation) to be altruistic in order to help others. I do this at great personal (emotional, psychological, financial) sacrifice, even if I personally feel like shit after. Even if it comes out wrong. Even if I end up regretting doing it (I often do, to some degree). It's pointless to think of it somehow benefiting me if my own pleasure is completely temporary (a few moments) against the long-lasting effects that altruistic, and humanistic efforts can have.
By disregarding (or not knowing) your own self-interests, you are then forced to think of the well-being of others First, and how you can make everything more fair - even if it has the potential to hurt you in the future.
This is why I always have complete transparency built-in to the "systems"/organizations I design and lead. Even making documents public amongst the volunteers, or streamlining procedures so that they aren't so convoluted and are more transparent, increases accountability amongst everyone, and therefore the credibility of the system.
