It is a strange, blind sort of world we are in, with lots of blind alleys, down which we go blundering in the fog after some seedy gaslight, which we take for the sun till we run against the wall at the end, and find out that the light is a gaslight, and that there’s no thoroughfare. But for all that, one does get on. You get to know the sun’s light better and better, and to keep out of the blind alleys; and I am surer and surer every day that there’s always sunlight enough for every honest fellow, and a good sound road under his feet, if he will only step out on it.
