_Quest._ III. Doth not the law of nature oblige us to serve God to the utmost of our power? He that denieth it, is become unnatural, and must deny God to be God, or deny himself to be his rational creature: for nothing is more clear in nature, than that the creature who is nothing, and hath nothing but from God, and is absolutely his own, doth owe him all that he is able to do. _Quest._ IV. Doth not Christ determine the case to his disciples, Luke xvii. 10? A middle between good and evil in morality is a contradiction: there is no such thing; for good and evil are the whole of morality: without these species there is no morality. _Object._ II. It seems then you hold that there is nothing indifferent, which is a paradox. [Sidenote: Whether any things be indifferent?] _Answ._ No such matter: there are thousands and millions of things that are indifferent; but they are things natural only, and not things moral. They are indifferent as to moral good and evil, because they are neither; but they are not _indifferentia moralia_: the indifferency is a negation of any morality in them _in genere_, as well as of both the species of morality.[50] Whatsoever participateth not of virtue or vice, and is not eligible or refusable by a moral agent as such, hath no morality in it. There may be two words so equal as it may be indifferent which you speak; and two eggs so equal, as that it may be indifferent which you eat; but that is no more than to say, the choosing of one before the other is not _actus moralis_: there is no matter of morality in the choice. _Object._ III.
