Researchers in the Netherlands are exploring courage among children, to see when the urge for courage first arises, and what children mean when they call themselves brave.

The theme of courage claims a long and gilded ancestry. Plato included courage among the four cardinal or principal virtues, along with wisdom, justice and moderation.
勇气这个主题有着久远而辉煌的历史。柏拉图把勇气与智慧、正义及节制一起，列为四种体液或称之为四美德。
"As a major virtue, courage helps to define the excellent person and is no mere optional trait," writes George Kateb, a political theorist and emeritus professor at Princeton University. "One of the worst reproaches in the world is to be called a coward."
"作为一项主要美德，勇气帮助我们定义优秀之人，它不是可有可无的选项"，普林斯顿大学的政治理论家和名誉教授乔治·卡泰（George Kateb）说："这个世界上最糟糕的指责之一就是被称为懦夫"。
Yet defining what it means to be courageous has often proved as thistly as distinguishing the wise ones from the fools. For Plato and many other authorities, courage is above all a martial art, most readily displayed on the battlefield — the iconic brave solder running into the line of fire to retrieve an injured comrade.
