Recipe for Evil/The Tyranny of the Ego:
1) Overidentify with a cause.
2) Elevate personal goals over concern for human consequences of decisions.
3) Lack empathy.
This is every one of us in a nutshell, most of the time.
It is the human responsibilty of the "normal" person in my little example to make his brain more like the Tibetan monk's. Persistent living in denial & failure to do so has evil consequences not only for the one in error, but for everyone. No one can ever be perfect & that is why the New Testament was written to not overly judge & to show that life is a process. Ultimately, we shouldn't ever pigeonhole someone as absolutely evil because all is stages on life's way. Still, one must have cause for concern & take the steps necesary to ever possibly break the tyranny of the ego or else one persists in error & truly never knows themselves.
Recipe for Good/Socratic principles on parade:
1) Self-knowledge is the sufficient condition to the good life. Knowledge cen be identified as related to virtue. If knowledge can be learned, so can virtue. Thus, virtue can be taught.
2) The unexamined life is not worth living. One must seek knowledge and wisdom before private interests. Knowledge is sought as a means to ethical action.
3) What one truly knows is the dictates of one's conscience or soul: the philosophy of the
Socratic Paradox; i.e., that your life should be spent on the improvement of your soul.
