Nor is It at All Prudent for The Hunter to be Over

Nor is it at all prudent for the hunter to be over curious touching the precise nature of the whale spout. It will not do for him to be peering into it, and putting his face in it. You cannot go with your pitcher to this fountain and fill it, and bring it away. For even when coming into slight contact with the outer, vapoury shreds of the jet, which will often happen, your skin will feverishly smart, from the acridness of the thing so touching it. And I know one, who coming into still closer contact with the spout, whether with some scientific object in view, or otherwise, I cannot say, the skin peeled off from his cheek and arm. Wherefore, among whalemen, the spout is deemed poisonous; they try to evade it. Another thing; I have heard it said, and I do not much doubt it, that if the jet is fairly spouted into your eyes, it will blind you. The wisest thing the investigator can do then, it seems to me, is to let this deadly spout alone.
Still, we can hypothesize, even if we cannot prove and establish. My hypothesis is this: that the spout is nothing but mist. And besides other reasons, to this conclusion I am impelled, by considerations touching the great inherent dignity and sublimity of the Sperm Whale; I account him no common, shallow being, inasmuch as it is an undisputed fact that he is never found on soundings, or near shores; all other whales sometimes are. He is both ponderous and profound. And I am convinced that from the heads of all ponderous profound beings, such as Plato, Pyrrho, the Devil, Jupiter, Dante, and so on, there always goes up a certain semi-visible steam, while in the act of thinking deep thoughts. While composing a little treatise on Eternity, I had the curiosity to place a mirror before me; and ere long saw reflected there, a curious involved worming and undulation in the atmosphere over my head. The invariable moisture of my hair, while plunged in deep thought, after six cups of hot tea in my thin shingled attic, of an August noon; this seems an additional argument for the above supposition.

And how nobly it raises our conceit of the mighty, misty monster, to behold him solemnly sailing through a calm tropical sea; his vast, mild head overhung by a canopy of vapour, engendered by his incommunicable contemplations, and that vapour—as you will sometimes see it—glorified by a rainbow, as if Heaven itself had put its seal upon his thoughts. For, d'ye see, rainbows do not visit the clear air; they only irradiate vapour. And so, through all the thick mists of the dim doubts in my mind, divine intuitions now and then shoot, enkindling my fog with a heavenly ray. And for this I thank God; for all have doubts; many deny; but doubts or denials, few along with them, have intuitions. Doubts of all things earthly, and intuitions of some things heavenly; this combination makes neither believer nor infidel, but makes a man who regards them both with equal eye.
Other poets have warbled the praises of the soft eye of the antelope, and the lovely plumage of the bird that never alights; less celestial, I celebrate a tail.
