"We understood that our vocation, our true vocation, was to move for eternity along the roads and seas of the world. Always curious, looking into everything that came before our eyes, sniffing out each corner but only very faintly – not setting down roots in any land or staying long enough to see the substratum of things; the outer limits would suffice."
