Teaching sometimes seems like not one profession, but every profession. We ask them to be doctor and diplomat, calf-herder, map-maker, wizard and watchman, electricians of the mind.

A lot of parents today are terrified that something they say to their children might make them 'feel bad.' But, hey, if they've done something wrong, they should feel bad. Kids with a sense of responsibility, not entitlement, who know when to experience gratitude and humility, will be better at navigating the social shoals of college.

To maximise global social welfare, policymakers should strongly encourage the diffusion of knowledge from developed to developing countries.

Children, by nature, are keen, passionate and curious. What was referred to as laziness is often merely an awakening of sensitivity, a psychological inability to submit to certain absurd duties, and a natural result of the distorted, unbalanced education given to them. This laziness, which leads to an insuperable reluctance to learn, is, contrary to appearances, sometimes proof of intellectual superiority and a condemnation of the teacher.

In our relationship with children and young people, we are not dealing with mechanical devices that can be quickly repaired, but with living beings who are impressionable, volatile, sensitive, afraid, affectionate; and to deal with them we have to have great understanding, the strength of patience and love.

Books are the perfect Time Machine. By the simple act of opening a book you can, in an instant, be travelling up a jungle river without once being bitten by mosquitoes, or you can almost die of thirst in the desert while holding a cold drink in your hand, or dine in the finest restaurants and never have to worry about paying the bill, or ride the wild country of our western frontier and never worry about losing your scalp to a raiding party.
