选自《论语·为政》古人质实,不尚智巧,言论未详,事实先著。——宋·陆九渊《与朱元晦书》中译英Say yes if you know, say no if you do not know, which is the wise behaviour.知之为知之,不知为不知,是知(知:zhì四声,通“智”)也。when you know a thing, to hold that you know it; and when you do not know a thing, to allow that you do not know it.当你知道一件事,说你知道它;当你不知道一件事,容许你说不知道它。
