This project traces how, why, and under what circumstances scholars invoked the trope of “dogmatism,” especially in controversies. Relevant controversies from various fields, periods, and countries will be subjected to in-depth rhetorical analysis.

Why did 'character', 'habit', and 'virtue' serve as key terms in late 19th and early 20th-century scholarly correspondences, biographies, and obituaries? Why did scholars around 1900 display so much interest in the working habits and character traits of what they called the 'scholarly self'?

What evaluative languages (errors, mistakes, vices, etc.) did book reviewers employ? To what extent and on what occasions did they invoke early modern vices? And to what extent did this differ across fields or change over the course of the century?

If idioms employed in codes of conduct could be as idiosyncratic as examples suggest, then to what extent did early modern language of vice, too, persist in this genre?

What makes a good historian? When historians raise this question, as they have done for centuries, they often do so to highlight that certain personal attitudes or dispositions are indispensable or studying the past. Yet their vieuws on what virtues, skills or competencies historians need most differ…

Drawing on a broad array of sources, this project examines modern retrievals of Bacon’s idols, thereby testing Justus von Liebig’s intriguing observation, back in 1863, that Bacon’s name lived on mainly in mottos or stereotypical phrases.
