“Much of the social history of the Western world over the past three decades has involved replacing what worked with what sounded good. In area after area - crime, education, housing, race relations - the situation has gotten worse after the bright new theories were put into operation. The amazing thing is that this history of failure and disaster has neither discouraged the social engineers nor discredited them.”

Final address (1973)
Context: Placed in a historic transition, I will pay for loyalty to the people with my life. And I say to them that I am certain that the seeds which we have planted in the good conscience of thousands and thousands of Chileans will not be shriveled forever. They have force and will be able to dominate us, but social processes can be arrested by neither crime nor force. History is ours, and people make history.

This and That and the Other (1912)
Context: The Barbarian hopes — and that is the very mark of him — that he can have his cake and eat it too. He will consume what civilisation has slowly produced after generations of selection and effort but he will not be at pains to replace such goods nor indeed has he a comprehension of the virtue that has brought them into being. Discipline seems to him irrational, on which account he is for ever marvelling that civilisation should have offended him with priests and soldiers.
