Again, happiness is defined according to my sliding scale. One such maxim is, again, that all people should be treated equally. I judge this maxim to be a law, because I think there is more happiness in the world when it is applied as a universal law than when it isn't. I must not violate this law, so I have to vote for equal distribution of the antidote. Granted, I am aware that I have only made this decision because I believe it will make me the most happy, but that was not foremost in my considerations.
Moral doctrines are difficult to fathom.
They are created to provide support for one's moral decisions, and once they have been created are directly used to help make those decisions. In the context of hard determinism or even moral compatibilism it seems like an absurd process. For that purpose, I'm glad to have formulated my own, because neither Kant's, Rand's, nor Mill's is sufficient by itself. References Kant, Immanuel. The Good Will.
