'It's an interesting exercise to go through your books, evaluating each one for its impact. First there are those that have shaken you so much that you never got beyond page 23. Then there are those that you read because they feature on the lists of must-reads that prey on our inadequacies.
Though there is little in the way of business books on my shelves, the Very Short Introductions series from OUP has found its way there, covering Capitalism, Globalization and Climate.
Finally, I plumped for Daniel Dennett's Consciousness Explained as the latest in a line of books that have shaped the way I think about how people behave. It moves through psychology, neurology and computer AI theory to support a view of consciousness as a series of drafts yet to be finalised.

It holds the record in my library for the greatest number of must-follow-up notes - much of which, I fear, will have to wait until my retirement.'
