The Faculty of Philosophy at Universitas Gadjah Mada once again hosted its regular Great Philosopher discussion series, this time focusing on a significant topic in metaethics: the Error Theory of Morality by philosopher J.L. Mackie. The discussion took place at the Faculty of Philosophy Library Reading Room and was led by Gladwin Panjaitan as the speaker, with Alfred Brilian Bassang serving as moderator.
During the session, Gladwin reviewed J.L. Mackie’s ideas as presented in his book Ethics: Inventing Right and Wrong (1977), where Mackie proposed a skeptical moral approach he termed the Error Theory. This theory acts as a critical response to the then-dominant Emotivism by arguing that linguistic analysis alone is insufficient to fully grasp moral reality.
