Here's the gist of what it says.
Human beings are such creatures. Society wants to see an upright character in a person. The more consistently upright, the more reliable you are deemed. So everyone plays along to be ostensibly in line with this goal while hiding their traits that are not. If you eventually get rid of those negatives you've been hiding, you have a consistently upright life. On the other hand, if you start to reveal them, things fall apart around you.
