A lot of what you said here was confusing and vague for me

how do you understand egoism and its relation to altruism

don't egoists think that you can only act in your own interest and that there are people who recognise that and people who don't?

it's not clear to me how altruism exists or that the dichotomy between altruism and selfishness makes any sense

but it's weird because it seems like you're suggesting we use the master's tools to take down his house, in that last paragraph of yours
