In Latin the difference between liber and liber–freedom and book–is an emphasis on the i. It’s not a coincidence. Books were little packets of freedom. But their concept of freedom was not limited to a generic sense of unrestricted. Unlike most ‘modern’ ideas surrounding freedom, it was not freedom from responsibility but freedom for responsibility. Books did not exist to unshackle minds, though they certainly did that, but they made minds more. Muchier. Stronger, in a sense. A Roman education was to make free men, and these free men would have the mental ability to carry a heavier burden. But even the greatest Roman was always a slave to his father. No one was free, except those who were especially burdened by responsibility.
