Like anything, it kinda boils down to a linguistic clusterfuck. What do we mean by “inherent” and “good”? Daoism/Buddhism holds that were are ‘inherently good’ when we are born, either due to our naive nature or due to our Buddha nature (both of which pretty much boil down to the same thing). Orthodox Confucianism holds that we are ‘inherently good’ because we contain within us the potentiality of becoming a sage, the highest realization of the ‘good’ as defined by Confucianism. Orthodox Christianity holds that we are ‘inherently bad’ and that goodness exists as something that their god gives us through ‘grace’. Heterodox Confucianism holds that we are ‘inherently bad’ because of those fundamental aspects of humanity which cause strife and suffering.
There are numerous takes on this theme, but they all boil down to perspective. Human beings can be violent, chaotic, destructive, and a variety of other things which we humans consider to be ‘bad’. Human beings can also be loving/benevolent, honorable, wise, just, filial, and a variety of other things which we humans consider to be ‘good’. So where do we draw the line with respect to a question like this? Which have we seen more of, which aspects of the human condition affect us more and which aspects of the human condition are we seeking to address? No right or wrong answer, since humans are a combination of both.
I think human beings are inherently good because of the potentiality for goodness which we embody and the goodness which we actualize. I’m an optimist like that. But it boils down to the concept of the beauty of virtue and the deformity of vice. I believe (and neurologists and sociologists have gone a long way towards affirming) that human beings possess an innate moral grammar which affirms the basic premise of the beauty of virtue and the deformity of vice. But that in no way argues against deformities which are present in the world. Likewise, a Christian, a Xunzian, a Jainist, or any other number of ideologies can point to those deformities and argue that humans are inherently bad and that goodness is a deviation from the norm.
Which brings us to the normative nature of the terms we are using and how we want to apply them. An idealistic person (not to be confused with an idealist, damned terminology) can’t help but think that human beings are bad, after all, as a class we so routinely fail to actualize the good. A more pessimistic person can’t help but think that human beings are good, after all, we deviate from the bad incredibly regularly.
For me, since we can discuss concepts of good and bad and find almost universal agreement, I’m inclined to say that we are inherently good, that is, it is human nature to be good. But we are inherently good in the same way that an acorn is inherently an oak. We all know that an acorn isn’t an oak. But if an acorn develops according to its nature it becomes an oak. One could just as easily say that it is an acorn’s nature to be food for a squirrel or rotting on the ground. More acorns end up as fodder for animals or rotting on the ground than become oaks, after all. So do we want to be idealistic and then let down by failures to actualize the ideal or are we pessimistic and embrace those rare specimens which actualize the ideal? Perspective.
