To justify something is to say that why it is said to be good or bad, just or unjust. To justify x, is not to say of x that it is right but to show that x is right. What we evaluate is to justify. Evaluation and justification are two different things. Such a distinction is clearly pointed out by Hodgson.
Moral justification is required for the assertion made on the object of moral judgement.
Moral justification meets the why-questions. To meet this why-question , one who justifies is to put forth reason for which moral judgement is made. Moral justification, therefore, involves reasoning. According to J. Hartland-Swann, reference to certain factors as reason is required for the justification of moral judgement. Raphael's statement is not linguistically sound.
