The human being is born with an inclination toward virtue.
Musonius Rufus, Lectures, 2.7.1-2
I remember the very moment I moved from the religious segment of the population to the non-religious segment of the population. My family is Catholic on my mothers side, and I spent a decent amount of my childhood doing all of the traditional things: Sunday school, religious readings, countless church ceremonies, and painfully long services during the holidays. In general it seemed fine; it was even fun sometimes. And then one day it came time for First Confession, and I just did not understand the concept.
Why does everyone assume they are bad? Sure, maybe we have done some stuff we regret and we may want to talk about it, but why is the assumption that I need to confess that I did something wrong? I mostly felt like I was just being a pretty normal kid that did normal kid stuff. What was wrong with that? And then I started thinking more about original sin, and it pushed me away even further. Everyone is a sinner because someone screwed up thousands of years ago? That doesn’t even make sense.
But what Musonius Rufus says above does make sense. We are born with an inclination toward virtue. Evolution favors those who are willing to work together and be kind to each other. Our default mode of operation when we are born is to not be an asshole; that is something a few people learn along the way. That means there is hope in this too. You were born good. If you are no longer good, or perhaps just not as good as you would like to be, you have simply deviated from your baseline. It is not your destiny. It is a matter of seeking out better ideas and behaviors, and then spending the time and energy to focus on returning to the original you.
