the.com/callousness
the emotional equivalent of a calloused hand — built by repeated friction, useful and dead to touch
means A hardened indifference to others' suffering or feelings, an inability or unwillingness to be moved by pain.
from From Latin callus, callum — literally the thickened, hardened skin that forms on a hand or foot after repeated rubbing. English took 'callous' first as a medical term for that toughened flesh, then carried it across into the soul: a heart that had been rubbed often enough to stop feeling. 'Callousness' is simply that hardness made into a noun — the abstract state of skin that no longer registers the touch.
