Big Identity

A common failure mode in human reasoning is to become too attached to theory, to the point where we begin ignoring the reality it was intended to describe. The way this manifests in ethical and moral reasoning is that we tend to forget why we make rules – to avoid harmful consequences. Instead, we tend to become fixated on the rules and the language of the rules, and end up fulfilling Santayana’s definition of a fanatic: one who redoubles his efforts after he has forgotten his aim.
