Quality

If you want to build a factory or fix a motorcycle, or set a nation right without getting stuck, then classical, structured dualistic subject-object knowledge, although necessary, isn’t enough. You have to have some feeling for the quality of the work. You have to have a sense of what’s good. That is what carries you forward. This sense isn’t just something you’re born with, although you are born with it. It’s also something you can develop. It’s just not “intuition”, not just unexplained “skill” or “talent”. It’s the direct result of contact with basic reality, Quality, which dualistic reason has in the past tended to conceal.
