Lack of progress?

Don’t you see that this is why we make no progress, why we find we have not been helped towards it? We remain all the time against one another, grinding one another down. Because each considers himself right and excuses himself, as I was saying, all the while keeping none of the commandments yet expecting his neighbor to keep the lot! This is why we do not acquire habits of virtue, because if we light on any little thing we tax our neighbor with it and blame him saying he ought not to do such a thing and why did he do it - whereas ought we not rather to examine ourselves about the commandments and blame ourselves for not keeping them?
