H. P. Grice quotes, to disagree, from S. H. Hampshire and H. L. A. Hart, when they say that "the agent's certainty about what he will do comes at the moment of decision, and indeed constitutes the decision, when the certainty is arrived at, as a result of considering reasons, and NOT as a result of considering EVIDENCE. When he has made his decision, THAT IS, when, after considering reasons, all UNCERTAINTY [to use H. P. Grice's expression] about what he is going to do has been removed from his mind, he will be said to INTEND to do whatever he has DECIDED to do, UNLESS he falls into UN-certainty [Grice's expression] again, as a result of further reasons suggesting themselves, or until he DEFINITELY changes his mind!" -- "That was enough for me for willing, and possibly deciding, with an uncertainty of degree d2, that my B. A. lecture be on "UN-certainty"!
