still small voice, a

One’s conscience. This term comes from the Bible, where the prophet Elijah hears his own inner voice: “And after the earthquake a fire; but the Lord was not in the fire: and after the fire a still small voice” (1 Kings 19:12). The term was used frequently thereafter by poets such as Gray, Cowper, Byron, and Tennyson, as well as by Erasmus Darwin (Charles’s grandfather): “Inexorable conscience holds his court, With still, small voice the plot of guilt alarms” (Mores Concluded, ca. 1794). It is heard less often today.
