People who reject absolute standards of right and wrong are often inconsistent. When they think they are being treated unfairly, they appeal to a standard of justice that they expect everyone to adhere to.
A philosophy professor began each new term by asking his class, “Do you believe it can be shown that there are absolute values like justice?” The free-thinking students all argued that everything is relative and no single law can be applied universally. Before the end of the semester, the professor devoted one class period to debate the issue. At the end, he concluded, “Regardless of what you think, I want you to know that absolute values can be demonstrated. And if you don’t accept what I say, I’ll flunk you!” One angry student got up and insisted, “That’s not fair!” “You’ve just proved my point,” replied the professor. “You’ve appealed to a higher standard of fairness.”
