From the book Curious by Ian Leslie. Like the analogy of browsing a bookstore vs booking a train ticket.
Economist John Maynard Keynes once offered advice on how to conduct oneself in a bookstore: “A bookshop is not like a railway booking-office which one approaches knowing what one wants. One should enter it vaguely, almost in a dream, and allow what is there freely to attract and influence the eye. To walk the rounds of the bookshops, dipping in as curiosity dictates, should be an afternoon’s entertainment.”
This is far different from the advice you’d give someone on how to use Google, which, in Keynes’s terms, is more like a railway booking office—a place to visit when you know your destination.
