Poets do not tell you what they feel. They show you how they feel. Philosophers don't tell you what they think, but show you how they do it.
No one can tell you what to think or feel. But some can help you do it better. Our poets make us feel better. Philsophers make us think better.
It's not that they give us better thoughts or better feelings. They hone our concepts and emotions, to make our minds and hearts precise.
