Will Thinking Right Automatically Make You Feel Good?

Q: You are clearly knowledgeable at both Psychology, and Philosophy. . In your view, can a good philosophy prevent a bad psychology?
Is a rational philosophy (e.g. Ayn Rand’s, The Fountainhead) enough for living a happy life, more so than a stable psychology?

My reply: A good philosophy is implied in a good psychology. But you can’t subscribe to a good philosophy and then just automatically start feeling good. You have to live the philosophy, and test it, and integrate it in order to benefit from it. On the other side, you can have a good psychology with no philosophy, or with a philosophy that contradicts it. But you’ll be hampered, at best, by the contradiction.
