Some people will have that aiming for a maximiation of happiness is often not the right way of, in fact, reaching it. How do you respond to those kinds of concerns about utilitarianism? Some of those points that you made are true. The greeks are already aware of what they call the paradox of heathenism. If you aim directly at pleasure, you're less likely to actually achieve it than if you find something worth while to do and succeed in that. That's something that i've emphasized in my work about altruism and about helping people in poverty. And something like that may be true at the level of public policy as well.
