This is, therefore, a need for an absolutely necessary aim, and it justifies its presupposition not merely as a permitted hypothesis, but as a postulate for a practical aim; and, granted that the pure moral law unremittingly obligates everyone as a command (not as a rule of prudence), the righteous person may indeed say: I will that there be a God, that my existence in this world be even apart from the natural connection also an existence in a pure world of understanding, and finally that my duration be endless; I abide by this, and shall not let this faith be taken from me; for, this is the only case where my interest, because I must remit anything of it, unavoidably determines my judgment, without paying attention to subtle reasonings, however little I may be able to answer them or oppose them with more plausible ones.
