Feelings: The need for a new science

On feelings, in a completely different way... The fact that I can explain why Phineas P Gage used foul language may be interesting only to a few neurologists or psychologists at best. My statement that Descartes's famous saying "Cogito ergo sum", i.e. "I think, therefore I am" should be modified to "Sentio ergo sum", i.e. "I feel, therefore I am" will give a real headache only to a few philosophers. "Okay, but then why should simple mortals read this book?" you may ask. Because it can help you find your way in the world, one of the many individual worlds, but the only world that exists for you as well: the world of feelings - the world of your feelings.
