--- this may relate to Kant's and Grice's point that an imperative -- cfr. categorical imperative, hypothetical imperative) in a way reduces to an indicative.

"If you want a healthy life style, don't smoke"

This is only valid provided the corresponding alethic conditional holds water. Or something. I will have to revise this. It's in the last lecture for the John Locke (in Grice, 2001).

Simply, Grice's point is

"if you want to be happy, do x!"

In this way, he can coordinate Kant with Aristotle, and get to Kantotle (or Ariskant). The last chapter of Grice 2001 indeed is an appendix on 'happiness'. While he thinks it does not quite fit in the Locke format, it does. If we see happiness as involved in the protasis of the imperative that Kant is talking about when revising the categoricity of morality. Or something.
