In the Propontis, as far as I can learn, none of that peculiar substance called brit is to be found, the aliment of the right whale. But I have every reason to believe that the food of the sperm whale— squid or cuttle-fish—lurks at the bottom of that sea, because large creatures, but by no means the largest of that sort, have been found at its surface. If, then, you properly put these statements together, and reason upon them a bit, you will clearly perceive that, according to all human reasoning, Procopius’s sea-monster, that for half a century stove the ships of a Roman Emperor, must in all probability have been a sperm whale.
Though, consumed with the hot fire of his purpose, Ahab in all his thoughts and actions ever had in view the ultimate capture of Moby Dick; though he seemed ready to sacrifice all mortal interests to that one passion; nevertheless it may have been that he was by nature and long habituation far too wedded to a fiery whaleman’s ways, altogether to abandon the collateral prosecution of the voyage. Or at least if this were otherwise, there were not wanting other motives much more influential with him. It would be refining too much, perhaps, even considering his monomania, to hint that his vindictiveness towards the White Whale might have possibly extended itself in some degree to all sperm whales, and that the more monsters he slew by so much the more he multiplied the chances that each subsequently encountered whale would prove to be the hated one he hunted. But if such an hypothesis be indeed exceptionable, there were still additional considerations which, though not so strictly according with the wildness of his ruling passion, yet were by no means incapable of swaying him.
To accomplish his object Ahab must use tools; and of all tools used in the shadow of the moon, men are most apt to get out of order. He knew, for example, that however magnetic his ascendency in some respects was over Starbuck, yet that ascendency did not cover the complete spiritual man any more than mere corporeal superiority involves intellectual mastership; for to the purely spiritual, the intellectual but stand in a sort of corporeal relation. Starbuck’s body and Starbuck’s coerced will were Ahab’s, so long as Ahab kept his magnet at Starbuck’s brain; still he knew that for all this the chief mate, in his soul, abhorred his captain’s quest, and could he, would joyfully disintegrate himself from it, or even frustrate it. It might be that a long interval would elapse ere the White Whale was seen. During that long interval Starbuck would ever be apt to fall into open relapses of rebellion against his captain’s leadership, unless some ordinary, prudential, circumstantial influences were brought to bear upon him. Not only that, but the subtle insanity of Ahab respecting Moby Dick was noways more significantly manifested than in his superlative
