Medieval monks thought a lot about thinking. As University of Georgia history professor Jamie Kreiner elaborates in a recent Aeon article:
“Their job, more than anything else, was to focus on divine communication. For these monks, the meditating mind wasn’t supposed to be at ease. It was supposed to be energised. Their favourite words for describing concentration stemmed from the Latin tenere, to hold tight to something. The ideal was a mens intentus, a mind that was always and actively reaching out to its target.”
To accomplish this goal “meant taking the weaknesses of their bodies and brains seriously.”
They used complex visual mnemonic techniques to help structure complex information in their mind’s eye.
They deployed heavy labor and moderate diet to keep their physiology in an optimal state for mental work.
Even the monastic renunciation of worldly goods and relationships supported concentration: the fewer things going on your life, they reasoned, the fewer things to distract you while trying to think about God.
What struck me as I read this article is that in our modern world, we still maintain positions in which the ability to concentrate is crucial to success: high skilled knowledge work jobs, like computer programmers, lawyers, doctors, consultants, journalists and professors.
