Has anyone described etc. Ataraxia from not asking needless questions? I am most familiar with the idea of ataraxy from Epicurus
if one is frightened by the empty name of death, the fear will persist since we must all eventually die. This fear is one source of perturbation (tarakhê), and is a worse curse than physical pain itself; the absence of such fear is ataraxy, lack of perturbation, and ataraxy, together with freedom from physical pain, is one way of specifying the goal of life, for Epicurus.
Is there anything analogous in the calmness of knowing when a question should have been asked or should be asked? Quite how anyone can know what a good question is, I'm not sure. But that's not the question.
