Ethical egoism-weakness 1
IT DESTROYS SENSE OF COMMUNITY
Cuts our links with other people. Morality= whats best for me, not you.
We have nothing in common with others than self-interest. Community is just people using eachother.
Cannot live in common- if the whole society followed egoism then surely law and order would break down. My self-interest is not the same as your self-interest, we will end up fighting.
