Context

“Strikes me a fellow ought to use his insight, not just a chest of tools, to make discoveries. A good sailor could find his way at sea even if he didn't have instruments, and a whole Lusitania-ful of junk wouldn't make a good sailor out of a dub. Man ought to develop his brain, not depend on tools." "Ye-uh, but if there were charts and quadrants in existence, a sailor that cruised off without 'em would be a chump!" For half an hour Martin defended himself, not too politely, before the gem-like Gottlieb, the granite Wickett.” source
