meditation 13. Will be discussing something basic, the fundamental value of philosophy. Marcus is asking us to have this tool with us at all times. Not all people have the benefit of knowing the beauty of good or the ugliness of evil because they have not been taught it. They have not found the philosophical path that you are on to know any better. We are born to work together, like feet, hands and eyes, like the two rows of teeth, pper and lower. Is unnatural to feel anger at some one, to turn your back on them. These are obstructions.
