One of my all-time favorite quotes comes from Wittgenstein: “A philosophical problem has the form: ‘I don’t know my way about.’ ” I love it for two reasons. First, it shows how philosophy is not an archaic style of theoretical speculation that has been supplanted by science. Philosophy is a perpetual discovery of new scientific turf. Philosophy pioneers what science settles and builds up.

But the other thing I love about the quote is it shows where philosophy can fit into the practical activities of everyday life. If you can’t intellectually move about in a problem space, you can’t work consciously and methodically. But what is innovation than looking for these areas? To extend my pioneering metaphor, in any exploration of innovative possibilities, philosophers ought to be brought along as guides to help navigate and map the territory.
