I am sympathetic to your argument, but would take it farther.<p>A person has no obliation to others, whatsoever, period.<p>Anyone who disagrees would have to overcome the burden of proof.<p>(Which you can&#x27;t, by the way, since I know things that would contradict a positive argument for obligation to others as it is generally conceived.)<p>---<p>Practically everybody makes moral assumptions purely based on emotions, possibly with some post-hoc rationalizations.<p>But our emotions didn&#x27;t have to be what they were---they vary between time periods, cultures, and individuals. Emotions are the product of premises that one has accepted, rationally or (for the most part today) irrationally.
