 There’s little doubt that Mill agreed with Clifford’s Rule. Mill was no subjectivist or fideist. But hope and belief are not the same; and the standards for the permissibility of the latter are considerably higher. Mill thought that (L1) and (L2) were the relevant standards for permissible hope. If one believes that Clifford’s Rule should govern any and all propositional attitudes and not just belief, then it is easy to see why Mill’s liberal treatment of hope would disappoint.
