The unique function of the nurse is to assist the individual, sick or well, in the performance of those activities contributing to health or its recovery (or to peaceful death) that he would perform unaided if he had the necessary strength, will or knowledge.
Surely it is a great thing to increase the numerous host of fixed stars previously visible to the unaided vision, adding countless more which have never before been seen, exposing these plainly to the eye in numbers ten times exceeding the old and familiar stars.Galileo Galilei

Economic man and the Calvinist Christian sing to each other like voices in a fugue. The Calvinist stands alone before an almost merciless God ; no human agency can help him; his church is a means to political and social organization rather than a bridge to deity , for no priest can have greater knowledge of the divine way than he himself; no friend can console him in fact , he should distrust all men; in the same fashion, Economic Man faces a merciless world alone and unaided, his hand against every other's.Lionel Trilling
