The demandingness problem asks whether an ethical theory requires too much sacrifice. Helping others can remain possible long after an ordinary life feels fully committed.

Imagine choosing between a personal hobby and another useful contribution to strangers. A theory that always requires the greatest benefit may repeatedly direct resources away from personal projects, not just in emergencies.
Slide 2
A single rescue is not everything
A small sacrifice in an urgent case may seem clearly required. Repeating similar demands indefinitely creates a different question about the shape of a life.

The difference concerns accumulation. Ten individually modest commitments can jointly displace sleep, relationships or meaningful pursuits. Evaluating each in isolation can miss the total burden imposed on the same person.
Slide 3

Thanking someone for exceptional generosity can coexist with saying that a less generous action would have been permissible. The category helps explain ordinary distinctions between failing a duty and declining an extraordinary sacrifice.
Slide 4

Slide 5
A limit needs a reason
Calling a demand excessive begins a debate rather than ending it. A proposed limit must explain whose interests it protects and why.
