Compared to hardened people, the hearts of rocks are comparatively soft.

"A hard, insensible man whom we liken to a rock is indeed much harder than a rock.  From hard, coarse, insensible people with whom I have no sympathy, I go to commune with the rocks, whose hearts are comparatively soft."

Henry David Thoreau
