Aristotle

Suffering becomes beautiful when anyone bears great calamities with cheerfulness, not through insensibility but through greatness of mind.

Greek Philosopher

Insensibility, of all kinds, and on all occasions, most moves my imperial displeasure.

Too much sensibility creates unhappiness and too much insensibility creates crime.

The state should, I think, be called 'anesthesia.' This signifies insensibility.

Describes someone who doesn't feel or show emotions, often seen negatively.

Can be used to talk about actual inability to feel physical sensations, not just metaphorical.

May imply someone is tough because they 'don't feel pain', but can be misunderstood.

Points to a lack of care or thought for others' feelings; can damage relationships.

Using 'insensibility' during an apology can seem insincere, as if blaming a condition.

Used in medical or technical contexts to describe a lack of consciousness.

Implies the person cannot wake up or respond on their own; often temporary.
