Many philosophically minded people throughout the ages have come to the conclusion that Happiness is the ultimate human intrinsic good because everything humans do ultimately seems to come down to attaining happiness or avoiding the things that make us unhappy.
But, are there no competing intrinsic goods that can be identified? For example, what of human free-will? If you could live a happy life, but while being controlled both physically and mentally by others, would that be acceptable to you? If the only way you could gain your freedom was at the cost of a significant amount of happiness would this be a rational decision to make?
If you were plugged into the Matrix and living a happy life, would you choose to sacrifice that happiness to live in a much more harsh, perhaps even miserable, world in order to attain freedom and truth?
