a concept of ancient Greek ethics, denoting calmness of the mind as the supreme value. Democritus understood ataraxy as the rule of reason over passions and the freedom of the soul from the fear of death and other misfortune. In the philosophy of Epicurus and his school, ataraxy is the highest ideal of life, the state of the wise man who has attained inner freedom. To skepticism ataraxy means restraint from judging the true and the false.
