"Suffering is something that is, purely and simply, connected to "being." Something cannot be "put into operation" without pain. Thus, pain is not a curse, nor a punishment, nor an anomaly, nor a maladjustment, nor a deviation, but the conditio sine qua non of being. Being is a condition of necessary suffering. Affirmative ethics, insofar as they respect the value of coherence, should not proclaim the elimination of pain as their concern."
