李斯
Three categories of books were viewed by Li Si to be most dangerous politically. These were poetry (particularly the "Shi Jing"), history ("Shujing" and especially historical records of other states than Qin), and philosophy. The ancient collection of poetry and historical records contained many stories concerning the ancient virtuous rulers. Li Si believed that if the people were to read these works they were likely to invoke the past and become dissatisfied with the present. The reason for opposing various schools of philosophy was that they advocated political ideas often incompatible with the totalitarian regime.
