The Moral Epistemological Argument

1. If we evolved and there is no God, then none of our moral beliefs are knowledge.
2. Some of our moral beliefs are knowledge.
3. We evolved.
4. So, there is a God.

Argument for 1

1. If we evolved and there is no God, then the truth of our moral beliefs is not a part of the explanation of why we have these beliefs.
2. If the truth of our moral beliefs is not a part of the explanation of why we have these beliefs, then these beliefs are not knowledge.
3. So, if we evolved and there is no God, then our moral beliefs are not knowledge.

A reliabilist response (Wielenberg)

• Reliable truth-tracking is sufficient for knowledge.
• Indirect evolutionary explanation: creatures that have T1 also have T2, and T1 is evolutionarily beneficial
• The belief that you have moral rights (i.e., there are “moral barriers” around you) is a reliable basic belief because the belief is true in anyone who has the belief
• The belief that others have moral rights follows from this and the Likeness Principle
