We learn nothing more than some basically common knowledge from primary to secondary school. Even if during four-year university life, we were taught only rudiments of scholarship. Universities are usually known as “the highest educational institution”, which is likely to cause the misunderstanding that there is no more to learn after university. The research institutes of universities are the certain places where knowledge is primarily studied. But even there you get only the first tasting of learning where focus on research method and practice. Knowledge is infinite and life is limited. Thus, ancient people never stop their study even when they were very old. However, there was strong interest in this process.
