How freely we live life depends both on our political system and on our vigilance in defending its liberties. How long we live depends both on our genes and on the quality of our health care. How well we live ~ that is, how thoughtfully, how nobly, how virtuously, how joyously, how lovingly - depends both on our philosophy and on the way we apply it to all else. The examined life is a better life.
If you want to improve your life, and also make the world a better place to inhabit, then it's time to consider another perspective on reason and passion, which doesn't view them as direct competitors.
