Socrates Jones: Pro Philosopher - Chapter 1: Euthyphro
Part 2 of 7, of a playthrough of "Socrates Jones: Pro Philosopher". Socrates Jones wakes up in an afterlife, populated with famous philosophers. The only way for him to escape is to explain morality so well that a judge known as the Arbiter is satisfied.
Socrates starts by speaking with Euthyphro, an ancient Greek philosopher who claims that morality comes from the gods. If the gods say something is good, that makes it good. Socrates counters, by pointing out that the gods sometimes disagree on what is good.
Euthyphro amends his argument, saying that something is good if all the gods agree on it. Socrates points out that if gods agree that something is good, then the agreement is not what makes it good. In other words, Euthyphro is making the circular argument that something is good, if the gods agree on it, and the gods agree on something, because it is good.
