Comment on literacy in Roman society..?

In Ancient Literacy W.V. Harris provides the first thorough exploration of the levels, types, and functions of literacy in the classical world, from the invention of the Greek alphabet about 800 B.C. down to the fifth century A.D. Investigations of other societies show that literacy ceases to be the accomplishment of a small elite only in specific circumstances. Harris argues that the social and technological conditions of the ancient world were such as to make mass literacy unthinkable. Noting that a society on the verge of mass literacy always possesses an elaborate school system, Harris stresses the limitations of Greek and Roman schooling, pointing out the meagerness of funding for elementary education.It gave some stimulus to critical thought and assisted the accumulation of knowledge, and the minority that did learn to read and write was to some extent able to assert itself politically. The written word was also an instrument of power, and its use was indispensable for the construction and maintenance of empires.
