Japanese "knowledge"

[caprinus]

In Japan silence is very important. Though you may feel uncomfortable, try to analyse what sort of a silence it is, whether it is a respectful silence or an upset silence. There is a definite connection between silence and wisdom. The Japanese character for Knowledge 知　combines the characters for losing 失 and mouth 口, which goes to show that the Japanese consider people wise who refrain from speaking. As the old proverb goes, “better to remain silent and be thought a fool, than to open your mouth and remove any doubt”. Some Japanese business books have also remarked on how westerners, especially Americans, feel uncomfortable with silence, so your associates may be trying to intimidate you.

So, is the bolded part total rubbish, the same as Chinese word for "crisis" = "danger" + "opportunity"?
