"There are times when the mind hesitates to enter a substantial book, aware that it will not be able to do justice. [...] I look for the slimmest volumes, nothing more than a hundred or so pages, nothing that cannot be finished in one sitting. Surprisingly, there are many and the pile soon builds up. [...] So sometimes, four slim books can add up to more than four slim books. Or perhaps there are times when things simply resonate more."
