“秀才不出门，全知天下事”，在技术不发达的古代只是一句空话，在技术发达的现代虽然可以实现这句话，然而真正亲知的是天下实践着的人，那些人在他们的实践中间取得了“知”，经过文字和技术的传达而到达于“秀才”之手，秀才乃能间接地“知天下事”。

The saying, “without stepping outside his gate the scholar knows all the wide world's affairs”, was mere empty talk in past times when technology was undeveloped. Even though this saying can be valid in the present age of developed technology, the people with real personal knowledge are those engaged in practice the wide world over. And it is only when these people have come to “know” through their practice and when their knowledge has reached him through writing and technical media that the “scholar” can indirectly “know all the wide world's affairs”.
