Both of those are just the simple negation of doing something.
Of course, to be is to do, so everyone is always doing something to some degree just by existing, but there is a continuum of different degrees of doing something in different contexts, and "doing nothing" / "not doing anything" in a given context is just doing negligibly much, such that the things that happen in that context are not noticeably different to what would have happened if you hadn't existed there at all.
Ok, but what Im asking is how you decided the prevention of greater loss of life in the trolley problem isnt obligatory. Walk me through your reasons for excluding it from obligatory in your diagram, I dont understand. — DingoJones
Preventing any loss of life is good, but only a supererogatory good; nobody can be obliged to prevent everything bad that happens, or even everything bad that they could possible prevent, or else you'd run into classic utilitarian problems like everybody who doesn't give everything they have and spent the entirety of their lives working exclusively for the benefit of those less fortunate than them are doing something wrong, that any concern for oneself at all is morally wrong. Sacrifice for others is good, but taking care of yourself is not
wrong, impermissible; it is permissible to let bad things go unfixed (even though it's supererogatorily good to fix them), it's only impermissible to cause new bad things yourself.
In the trolley problem, the choices presented are either do an impermissibly bad thing (kill someone) to achieve a supererogatory good (save some people), or else do nothing, in which case you fail to do the supererogatory good, but you also do not do something impermissibly bad. As permission and obligation are DeMorgan duals, you are obliged not to kill anyone, and conversely permitted to not save people, so
if you would
have to kill someone to save people, then it becomes impermissible to save them, at least that way.
Otherwise, it would be obligatory (or at least permissible) to kill one healthy patient and harvest their organs to save five dying people. I think that counter-example pretty clearly illustrates the problems with people's usual intuitions about the trolley problem. It's not okay to murder innocents to save more innocents, even though it's still good to save those more innocents -- but only if you can do it without murdering others.
