I think that in most cases when a man yields to temptation, judging that it is ``no use trying to resist'', he judges in semi-conscious self-sophistication, due to the influence of appetite or passion disturbing the process of reasoning. I do not doubt that this self-sophistication is likely to take a Determinist form in the mind of one who has adopted Determinism as a speculative opinion: but I see no reason for thinking that a Libertarian is not in equal danger of self-sophistication, though in his case it will take a different form. E.g. where a Determinist would reason ``I certainly shall take my usual glass of brandy to-night, so there is no use resolving not to take it'', the Libertarian's reasoning would be ``I mean to leave off that brandy, but it will be just as easy to leave it off to-morrow as to-day; I will therefore have one more glass, and leave it off to-morrow''.
