Are books more important than teachers?

That really deppends on the teacher. A good teacher would've excited his/her pupils and encouraged them to work. A bad teacher on the other hand, would probably not show her/his pupils respect and focus on other aspects then their subject (or provide false information!). A book would've been informative but dull (not exciting/encouraging the pupils, and also NB! altered information).

All in all, there's a reason for teachers (good teachers that is) and I'm really glad we have some of them.
