From Caring Comes Courage

...the most important term of Taoism: Tz’u, which can be translated “caring” or “compassion” and which is based upon the character for heart.

In the sixty-seventh chapter of the Tao Te Ching, Lao Tzu named it as his “first treasure,” and then wrote, “from caring comes courage.”

We might add that from it also comes wisdom. It’s rather significant, we think, that those who have no compassion have no wisdom. Knowledge, yes; cleverness, maybe; wisdom, no. A clever mind is not a heart. Knowledge doesn’t really care. Wisdom does. We also consider it significant that cor, the Latin word for “heart,” is the basis for the word courage.

Philosophers also use the word 'will'. Wisdom encompasses the moral understanding which is the business of understanding what we should do - what is right. And what is at the heart of the will if it is not love - or for Hoff - caring. I must care about something if I am going to stand up for something and that love or care is not produced by factual knowledge or intricate reasoning - it is a matter of the heart.
