"To be or not to be is" [by William Shakespeare] beyond anything I can comprehend. I understand it on a superficial level, but the depth of it just boggles my mind. I think it's probably the greatest of all speeches ever written.
Whether we love humanity or not, we must realize that we are part of it. My future depends entirely on the future of humanity, and so I am compelled to take care of humanity.

In ancient times, those who wished to illuminate the world with virtue first brought order to their nations. Wishing to order well their nations, they first harmonized their families. Wishing to harmonize their families, they first cultivated themselves. Wishing to cultivate themselves, they first rectified their minds. Those who wished to rectify their minds first made their intentions sincere.
