Thomas Aquinas had paper books.

 He was the big theologian who said man is different because of language.  He became philosopher of the church when large and famous universities were forming, often around he Catholic organization.
This was happening:

Moses Maimonides adopted Aristotelianism from the Islamic scholars and based his Guide for the Perplexed on it and that became the basis of Jewish scholastic philosophy. Although some of Aristotle's logical works were known to western Europe, it was not until the Latin translations of the 12th century that the works of Aristotle and his Arabic commentators became widely available. Scholars such as Albertus Magnus and Thomas Aquinas interpreted and systematized Aristotle's works in accordance with Catholic theology.

On ha basis is natural philosophy covered by religious philosophy.  Thomas waned all science under the roof of the church.  The era of great universities had begun and everyone had their own paper.

Socrates says there must be invisible force fields, Plato says no, If I got that right. It was Einstein and Planck all over again. Thomas took the Socrates literally, God makes thing happen with infinity perfection. surprisingly that worked, force fields, mysterious properties of nothingness, worked great. We built most of civilization under the assumption until about 1930.

I would call him a promoter of science in the language of the times.  And students all had paper, so watch what happens in these great Catholic universities.  Also, we are starting to see great literature, even before the printing press. But the printing press arrives and a great list of the new novels appear soon thereafter in 1400s.
