Dmitry Sergeevich Likhachev. Letters about the kind and beautiful (№ 201676)

Wisdom is the intelligence coupled with kindness. The mind without kindness was a trick. The trick is gradually wasting away, and certainly sooner or later turns against the bouncer. So the trick is forced into hiding. Wisdom is open and reliable. She does not deceive others, first of all, the wise man. The wisdom of the sage brings a good name and lasting happiness, happiness is a reliable, long-term and that quiet conscience which is more valuable in old age.
