At the wake of a trying day, at the moment where you feel no longer able to keep up appearances, you succumb, as all of us do inevitably, to our own basest drives. Are we inherently good, yes absolutely. We are born for good. We are molded by good things and even the 'worst' of us if a choice was presented to us would choose an inherently good world.
Plato believed that the entire city can be internalized and analyzed by the individual. I think when we should stop talking about 'faith' in the abstract and realize that belief, no matter how impervious we may feel towards such a sense, is wholly more outside the realm of religion than it is within it. Plato was a man of faith that with simple reflection chose to bet on us when sometimes in my own strongest moments I have felt to deny 'man' that same sentiment.
To know the darkest actions of man and to still believe in the purity of the individual is real wisdom. It is just so easy to blame instead of forgive, to judge instead of understand. To this moment I have seen myself as an ENTJ but I strive to be an INTP. Just because someone can speak doesn't mean someone should stop listening. Just because someone is in power means they should see themselves as wholly separate from the whole of mankind.
It's that little bit in us all that holds us back, that at times may feel like a strength but is our ultimate weakness. We much choose to stand above it all and to simply exist with the most open of hearts.
