i was frustrated in recent days, for sometimes i suddenly realize that i don't know the knowledge we learned is for what?
knowledge is power-- Bacon
and more details have been mentioned in his another saying' Histories make men wise, poets witty, the mathematics subtle, natural philosophy deep, moral grave, logic and rhetoric able to contend'
it's clear to tell us the meaning of learing. so it's funny why i owned such a frustrated feeling?
useless? or just i think it is useless?
