I’m not sure commission/omission distinction is really the key here. This becomes clearer by inverting the situation a bit:

Some third party is about to forcibly wirehead all of humanity. How should your moral agent reason about whether to intervene and prevent this?

Ah, nevermind then. I was thinking something like let b(x,k) = 1/sqrt(2k) when |x| < k and 0 otherwise

then define integral B(x)

f(x) dx as the limit as k->0+ of integral b(x,k)f(x) dxI was thinking that then integral (B(x))^2

f(x) dx would be like integral delta(x)f(x) dx.Now that I think about it more carefully, especially in light of your comment, perhaps that was naive and that wouldn’t actually work. (Yeah, I can see now my reasoning wasn’t actually valid there. Whoops.)

Ah well. thank you for correcting me then. :)
