Caledonian, I think you’re misreading him. He’s not saying: the cause is the one thing you never think rationally about. He’s saying: the cause is good (rationally good) and to protect/preserve it you have to pull yourself into conformance with the real world, because that’s where the action is. To achieve that you have to hold up what you (perhaps mistakenly) think of as “reason” against the real world, and be prepared to re-evaluate if it doesn’t work. What your re-evaluation seeks is better techniques of reason—not to throw reason away.
