Quotation by Alfred Kazin

Ishmael's thought consciously extends itself to get behind the world of appearances; he wants to see and to understand everything. Ahab's drive is to prove, not to discover; the world that tortures Ishmael by its horrid vacancy has tempted Ahab into thinking he can make it over. He seeks to dominate nature, to impose and inflict his will on the outside world—whether it be the crew that must jump to his orders or the great white whale that is essentially indifferent to him. As Ishmael is all rumination, so Ahab is all will. Both are thinkers, the difference being that Ishmael thinks as a bystander, has identified his own state with man's utter unimportance in nature. Ahab, by contrast, actively seeks the whale in order to assert man's supremacy over what swims before him as "the monomaniac incarnation" of a superior power.
