My first attempts to transmit typhus to laboratory animals, including the smaller species of monkeys, had failed, as had those of my predecessors, for reasons which I can easily supply today

The paradox of the human condition is expressed more in education than elsewhere in human culture, because learning to learn has been and continues to be Homo Sapiens' most formidable evolutionary task... It must also be clear that we will never quite learn how to learn, for since Homo Sapiens is self-changing, and since the more culture changes the faster it changes, man's methods and rate of learning will never quite keep pace with his need to learn.

If advertising has invaded the judgment of children, it has also forced its way into the family, an insolent usurper of parental function, degrading parents to mere intermediaries between their children and the market. This indeed is a social revoluation in our time!

To think deeply in our culture is to grow angry and to anger others; and if you cannot tolerate this anger, you are wasting the time you spend thinking deeply. One of the rewards of deep thought is the hot glow of anger at discovering a wrong, but if anger is taboo, thought will starve to death.

Up to a certain point anxiety is good, for it promotes action. Beyond that point we freeze any fixed attitudes or rush about without thinking deeply from one decision to another.

Most of the doctors in the Tunisian administration, especially those in country districts, contracted typhus and approximately one third of them died of it

The function of education has never been to free the mind and the spirit of man, but to bind them; and to the end that the mind and spirit of his children should never escape, Homo Sapiens has employed praise, ridicule, admonition, accusation, mutilation, and even torture to chain them to the culture pattern.
