One possible objection to Ayn Rand's argument is that her argument is based on false dichotomy (dilemma). Namely

		a) she falsely assumes that altruism implies that we always ought to sacrifice ourselves for others.
		b) she falsely assumes that egoism implies that we never should sacrifice ourselves for others.
		c) she ignores a possibility that we should reject both egoism and altruism and accept some other ethical theory.
		d) all of the above.
