Aristotle teaches us that those who are enslaved to passions, who never rise above their animal natures by practicing the virtues, do not have the most worthwhile opinions. Anger clouds good judgement. Those who exercise reason and attain practical wisdom on how to best live their own lives, order their household, and finally, when sufficiently wise and mature, should ideally venture opinions on how to best order the political community.
Jordan Peterson is a Canadian psychologist and professor at the University of Toronto. Peterson echos both Aristotle and the same sentiment that I wrote about in my post A Revolution Inside. He argues that unless we both understand and have control of our own negative qualities (or shadow self) we will project our worst impulses into the political arena while wearing a "mask of virtue." We need to work on ourselves first if we want to be an effective force for good and not end up doing more harm. If we want to see the world change, we must first concern ourselves with healing our own lives.
