What is moral knowledge?

What you know to be right and wrong based on our own experience. Though, this answer is somewhat misleading because how do you know what is right and wrong? There is not an entirely clear answer to this question. It could be the collection of desires that informs what is right and wrong, such as pleasure being right, but this, then, leads back to the naturalistic fallacy by G. E. Moore of whether or not good and bad can be defined, at all, even in terms of pleasure. Some will say the knowledge comes from our experiences, and other will say that it is rationalizations from our understandings of values and experiences we accept as standards of what is good and bad, still without defining good and bad in particular. In short, this is a question still being explored, and can also be relative to which brand of morality you adhere to: duty, virtue, or utilitarian.
