Human knowledge and skills alone cannot lead humanity to a happy and dignified life. Humanity has every reason to place the proclaimers of high moral standards and values above the discoverers of objective truth.
Love as a concrete foundation for an authentically functional civilization requires the around-the-clock labors of forgiveness. Without it, Love fails, Friendship fails, Intelligence fails, Humanity: fails.
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. That is why being compassionate is actually in my own best interest. And a symptom of my own peace of mind is that I can share comfort with others around me.
The Bhagavad-Gita calls on humanity to dedicate body, mind and soul to pure duty and not to become mental voluptuaries at the mercy of random desires and undisciplined impulses.

Hatred seemed to be the one faculty which had survived in undiminished vigor where all else was dropping into ordered and symmetrical decay.
Man is the will, and woman the sentiment. In this ship of humanity, Will is the rudder, and Sentiment the sail; when woman affects to steer, the rudder is only a masked sail.
