WE are now prepared to consider the question, whether each moral act, or exercise, is not always of a character purely unmixed? In other words, whether every such act, or intention, is not always perfectly right or perfectly wrong I would here be understood to speak of single acts, or intuitions, in distinction from a series, which continues through some definite period, as an hour or a day. Such series of acts may, of course, be of a mixed character; that is, it may be made up of individual acts, some of which are right and some wrong. But the question is, can distinct, opposite, and contradictory elements, such as sin and holiness, right and wrong, selfishness and benevolence, enter into one and the same act No one will pretend that an individual is virtuous at all, unless he _intends_ obedience to the moral law. The question is, can an individual intend to obey and to disobey the law, in one and the same act? On this question I remark, 1. That the principle established in the last Chapter really settles the question. No one, to my knowledge, pretends, that, as far as sincerity is concerned, the same moral act can be of a mixed character. Very few, if any, will be guilty of the folly of maintaining, that an individual can sincerely intend to obey and to disobey the law at one and the same time. When such act is contemplated in this point of light, it is almost universally admitted that it cannot be of a mixed character. But then another test is applied--that of intensity. It is conceivable, at least, it is said, that the intention might possess a higher degree of intensity than it does possess. It is, therefore, pronounced defective. On the same supposition, every moral act in existence might be pronounced defective. For we can, at least, conceive, that it might possess a higher degree of intensity. It has been abundantly established in the last Chapter, however, that there is no such test of moral actions as this, a test authorized either by reason or revelation. Sincerity is the only standard by which to determine the character and deserts of all moral acts and states. In the light of this standard, it is intuitively evident, that no one act can combine such contradictory and opposite elements as sin and holiness, right and wrong, an intention to obey and to disobey the moral law. 2. The opinions and reasonings of distinguished philosophers and theologians on the subject may be adduced in confirmation of the doctrine under consideration. Let it be borne in mind, that if the same act embraces such contradictory and opposite elements as sin and holiness, it must be, in reality, opposed to itself, one element constituting the act, being in harmony with the law, and in opposition to the other element which is opposed to the law.
