Theatres of the mind

I am not a big fan of lectures. The single best piece of advice I received at medical school was not to attend. I therefore skipped lectures for three years (although I got the handouts). It is not that all lectures are bad, they are not. It is just that often they are used for ‘content delivery’, much as we think about delivery of a takeaway. They are ill suited to this role, now that we can write and distribute text cheaply. Good lectures serve a different purpose, but you don’t need too many of them and, in my experience of medicine, there are very few people who lecture well. Lecturing well means choosing those fragments of a domain that lend themselves to this media type. Lectures are (and should be) theatre, but the theatre of the mind needs more.

By chance, I came across the following thoughts from the preface to the Ascent of Man (the TV series and the book). Bronowski understood many things, and I still marvel at how prescient his ideas were.

If television is not used to make these thoughts concrete, it is wasted. The unravelling of ideas is, in any case, an intimate and personal endeavour, and here we come to the common ground between television and the printed book. Unlike a lecture or a cinema show, television is not directed to crowds. It is addressed to two or three people in a room, as a conversation face to face – a one-sided conversation for the most part, as the book is, but homely and Socratic nevertheless. To me, absorbed in the philosophic undercurrents of knowledge, this is the most attractive gift of television, by which it may yet become as persuasive an intellectual force as the book.

The printed book has one added freedom beyond this: it is not remorselessly bound to the forward direction of time, as any spoken discourse is. The reader can do what the viewer and the listener cannot, which is to pause and reflect, turn the pages back and the argument over, compare one fact with another and, in general, appreciate the detail of evidence without being distracted by it.

Then there was PowerPoint and lecture capture.
