The “ascendant class” is the class that holds all the power—either political, social, or both—and which most people generally consider superior. “Morality” in this context is not limited to just beliefs or values, but codes of social conduct. “Moral” actions will tend to support those in power while “immoral” ones go against the desires of the ascendant class. Furthermore, Mill points out that in this system, opinions can become “law[s],” which implies that they will be enforced and any dissenters from them will be punished by society through their judgment and ill opinions.
