In a moral sense, lifeless denotes a want of vital energy; inanimate, a want of expression as to any feeling that may be possessed; dull implies a torpor of soul which checks all mental activity; dead supposes a destitution of feeling. A person is said to be lifeless who has lost the spirits which he once had; he is said to be inanimate when he is naturally wanting in spirits; one is dull from an original deficiency of mental power; he who is dead to moral sentiment is wholly bereft of the highest attribute of his nature.
