This is a reply deep in a thread on a relatively old post, you won't likely get many people that even see this request. :) If you're nervous about publishing a top-level post, at least float something on the discussion side. I agree that utilitarianism is severely flawed. My reason is that humans simply don't have enough computing power to ever implement utilitarianism decently, it would take an entity with orders of magnitude more intellectual strength to be a utilitarian with falling into a Bella spiral.

Deontology that is steered by utilitarian goals and occasionally modified by utilitarian analysis, OTOH, seems very workable and keeps the best of utilitarianism while factoring for human realities (but I've been plugging Desirism for a while now).
