LXVIII: The Blanket explained
Ishmael presents a detailed anatomical and philosophical meditation on the skin (or blubber) of the whale.
What happens
Ishmael presents a detailed anatomical and philosophical meditation on the skin (or blubber) of the whale. He argues that the whale's thick, insulating blubber should be considered its true skin, a 'blanket' that enables it to survive in all climates. He describes the markings on the skin as mysterious hieroglyphics and compares the whale's ability to maintain its own vital temperature to an ideal for human spiritual and physical resilience.
Themes in this chapter
Interpretation and Perception
The whale's skin is presented as a text to be read—its linear marks are 'hieroglyphical' and 'undecipherable,' challenging human understanding and inviting speculative interpretation.
Man vs. Nature
Explored through the whale's physiological mastery of its environment. Its blubber is a 'cosy blanket' allowing it to thrive in extreme conditions, which Ishmael holds up as a model for human endurance and spiritual independence ('live in this world without being of it').
Characters to notice
- Ishmael
Acts as the narrator and natural philosopher, analyzing the whale's integument with scientific curiosity and poetic reflection, drawing moral lessons for humanity.
- Moby Dick
The Sperm Whale is the primary subject of the chapter, its physical properties (blubber, skin, markings) serving as the basis for Ishmael's extended meditation.
Key passages
“Assuming the blubber to be the skin of the whale; then, when this skin, as in the case of a very large Sperm Whale, will yield the bulk of one hundred barrels of oil... some idea may hence be had of the enormousness of that animated mass...”
The sheer volume of oil yielded by the whale's blubber alone gives a sense of the creature's immense scale.
Emphasizes the whale's monumental physicality.
“Oh, man! admire and model thyself after the whale! Do thou, too, remain warm among ice. Do thou, too, live in this world without being of it.”
Ishmael exhorts humanity to learn from the whale: to maintain internal fortitude and spiritual independence amidst external adversity.
The core philosophical exhortation of the chapter.
“Like the great dome of St. Peter’s, and like the great whale, retain, O man! in all seasons a temperature of thine own.”
Just as the whale and the cathedral dome maintain their own internal conditions, so too should a person preserve their own inner constancy.
Extends the metaphor, linking natural and architectural wonders to human spiritual ideal.
