I agree that tact and politeness are still important social concepts. But one can be tact and polite without worrying or basing their entire behavior around their perceived affect on others. It is not our darkness that we fear, but our light.

And I do think this will catch on, I'm not speaking merely of whimsical fantasies, I'm speaking of evolutionary superiority. Acting earnestly, whether or not it looks pretty, accepting that we are always in transition, always practicing, refusing to shy away from behavior that we have not perfected, that may come off clumsy or amateur, this is the mark of an excellent human being and this is the wisdom that people who have succeeded in society preach to the rest of us.
