Why am I passionate about this?
I’m a historian of the early Middle Ages. There are all sorts of unexpected differences and similarities between modern and medieval life, and things get especially interesting when it comes to thinking about thinking. Our understanding of how our minds work has obviously changed—and so have the ways that we actually use them. Medieval thinkers in Europe and the Mediterranean world struggled with concentration and memory and information overload, just like we do. But they were savvier in dealing with those problems, and these books invite you into the wonderful world of their cognitive practices. You’ll probably find yourself experimenting with many of these techniques along the way!

As a bonus, the book is interlaced with its own horizontal tree diagrams. And who doesn’t love a meta-format?

We think with objects-we conduct our lives surrounded by external devices that help us recall information, calculate, plan, design, make decisions, articulate ideas, and organize the chaos that fills our heads. Medieval scholars learned to think with their pages in a peculiar way: drawing hundreds of tree diagrams. Lines of Thought is the first book to investigate this prevalent but poorly studied notational habit, analyzing the practice from linguistic and cognitive perspectives and studying its application across theology, philosophy, law, and medicine.
These diagrams not only allow a glimpse into the thinking practices of the past but also constitute a…
