Do you mean that you made a judgment elevating one value above another you had in cases where they conflict? Or do you mean you actually gained a new value? It seems like you must have used some sort of higher level value preference to make that meta-level moral judgment.

I noticed that my values were inconsistent, and I decided that one of them needed to be expunged. I removed a "value" that had been created at too high a level of abstraction, one which conflicted with the rest of my values and whose actual, important content could be derived from lower level moral concepts.
