[DeusExMachina]

Can you? A lot of psychological literature shows that we are far from being masters of ourselves.

Depresses people cannot reason themselves to any result at all. Addicted people cannot reason themselves out of addiction. You can fix many things with therapy, but that's far from just "reasoning" and takes a lot of time and work.

Emotions come from a much older part of your brain than the one for your reasoning skills, and thus have a far stronger pull on your actions. That's not to say we are completely at the mercy of our emotions. But controlling them is a matter of practice and reinforcement, not pure logic.
