“I have had considerable experience in dealing with minds of low logical power, and have found that studies may be made so easy and mechanical as to render thought almost superfluous.”

The Captive Mind (1953)
Context: As long as a society's best minds were occupied by theological questions, it was possible to speak of a given religion as the way of thinking of the whole social organism. All the matters which most actively concerned the people were referred to it and discussed in its terms. But that belongs to a dying era. We have come by easy stages to a lack of a common system of thought that could unite the peasant cutting his hay, the student poring over formal logic, and the mechanic working in an automobile factory. Out of this lack arises the painful sense of detachment or abstraction that oppresses the "creators of culture."

Golden Sayings of Epictetus
Context: What wouldst thou be found doing when overtaken by Death? If I might choose, I would be found doing some deed of true humanity, of wide import, beneficent and noble. But if I may not be found engaged in aught so lofty, let me hope at least for this—what none may hinder, what is surely in my power—that I may be found raising up in myself that which had fallen; learning to deal more wisely with the things of sense; working out my own tranquillity, and thus rendering that which is its due to every relation of life…. If death surprise me thus employed, it is enough if I can stretch forth my hands to God and say, “The faculties which I received at Thy hands for apprehending this thine Administration, I have not neglected. As far as in me lay, I have done Thee no dishonour. Behold how I have used the senses, the primary conceptions which Thou gavest me. Have I ever laid anything to Thy charge? Have I ever murmured at aught that came to pass, or wished it otherwise? Have I in anything transgressed the relations of life? For that Thou didst beget me, I thank Thee for that Thou hast given: for the time during which I have used the things that were Thine, it suffices me. Take them back and place them wherever Thou wilt! They were all Thine, and Thou gavest them me.”—If a man depart thus minded, is it not enough? What life is fairer or more noble, what end happier than his? (189).
