"The fact that a man has no claim on others (i.e. that it is not their
moral duty to help him & that he cannot demand their help as his
right) does not preclude or prohibit good will among men & does not
make it immoral to offer or to accept voluntary, non-sacrificial
assistance.  It is altruism that has corrupted & perverted human
benevolence by regarding the giver as an object of immolation, & the
receiver as a helplessly miserable object of pity who holds a mortgage
on the lives of others... leaving men no choice but the roles of
sacrificial victim or moral cannibal...   one must begin by rejecting
altruism's terms & all of its ugly emotional after-taste, then take a
fresh look at human relationships.  It is morally proper to accept
help, when it is offered, not as a moral duty, but as an act of good
will & generosity, when the giver can afford it (i.e. when it does not
involve self-sacrifice on his part), & when it is offered in response
to the receiver's virtues, not in response to his flaws, weaknesses or
moral failures, & not on the ground of his need as such."
