“I.P. was at that age when our sense of who we are, or of who we have been told we are, chafes against what we discover in our reading. And immediately a choice seems to appear: to let the reading show us the way forward, like water picking its course over unfamiliar ground; or to direct the reading, to channel the stream, so that it confirms what we already think we know. I.P. was among those few people who could do the former. He had a mind that welcomed doubt and uncertainty; he revelled in it, in fact; he was not one to ever make the perilous decision of deciding to know. His mind was happy to grope its way to its own conclusions, happy to breathe easy in a state of unknowing.”
