Although the initial focus of the humanist scholars in the university was the discovery, exposition and insertion of ancient texts and languages into the university, and the ideas of those texts into society generally, their influence was ultimately quite progressive. The emergence of classical texts brought new ideas and led to a more creative university climate (as the notable list of scholars above attests to). A focus on knowledge coming from self, from the human, has a direct implication for new forms of scholarship and instruction, and was the foundation for what is commonly known as the humanities. This disposition toward knowledge manifested in not simply the translation and propagation of ancient texts, but also their adaptation and expansion. For instance, Vesalius was imperative for advocating the use of Galen, but he also invigorated this text with experimentation, disagreements and further research. The propagation of these texts, especially within the universities, was greatly aided by the emergence of the printing press and the beginning of the use of the vernacular, which allowed for the printing of relatively large texts at reasonable prices.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What spread the use of texts by Galen within universities?
the printing press
