“A man may be set on fire like a candle, at either end”

“A man may be set on fire like a candle, at either end” is a comic expression that recasts desire as a bodily process whose outcome depends on where the flame is applied. Its mock physiology, literal interruption, and later application to Widow Wadman’s pursuit of Uncle Toby make the candle image both a joke about sexual appetite and a miniature pattern of the novel’s movement between abstract talk and intimate action.

The Image and Its Mock Physiology

The narrator begins from an observation about how a person may be set alight at either end, provided enough wick is exposed. If there is not, the attempt fails; if the candle is lit at the bottom, the flame is liable to put itself out. The apparent lesson is practical, but the human body has already made the comparison indecorous: a candle’s wick becomes an oblique figure for sexual capacity, while lighting it becomes a figure for arousal.

The narrator then imagines choosing how he himself would be burned. He rejects the prospect of being burned like a beast and prefers to be lit at the top, so that he might burn down decently from head to heart, liver, and bowels, following the mesenteric veins and arteries through the intestines and their tunicles to the blind gut. The itinerary parodies learned anatomical exposition: a conceit about desire expands into a rambling tour of the body, and the decorous language of orderly burning cannot hide its comic physical implications.

Literal Interruption and Comic Deflation

The anatomical lecture is interrupted when Uncle Toby asks Dr. Slop to identify the blind gut, confessing that despite his age he still does not know where it lies. Dr. Slop begins an anatomical answer, while Walter Shandy admits that he knows even less. Their exchange shifts the passage from the narrator’s elaborate metaphor to a practical gap in the listeners’ knowledge. The interruption does not resolve the sexual innuendo; instead, it makes the contrast between learned terminology and plain incomprehension part of the joke.

Widow Wadman’s Application of the Metaphor

The candle image returns when the narrator applies it to Widow Wadman’s courtship of Uncle Toby. She has determined not to light him at either end separately, but, like a prodigal’s candle, to light him at both ends at once. The expression thereby becomes more than a general reflection on desire: it figures Wadman’s deliberate effort to advance her suit from both directions and gives the earlier discussion its amorous target.

The military setting supplies the means of that approach. A map of whichever town or fortress Corporal Trim is working on is pinned inside the sentry-box, loose at the bottom so it can be lifted for viewing. Once Wadman has reached the door, the narrator describes her extending her right hand, edging in her left foot, and reaching toward the plan. The practical arrangement of map and sentry-box becomes part of the courtship scene, so that the phrase’s image of simultaneous attack is echoed by the physical staging of her approach.

Narrative Function

The expression binds together bodily metaphor, comic interruption, and the siege-like language of courtship. Its meaning changes with its setting: first a mock rule about the conditions of burning, then an invitation to anatomical digression, and finally a pointed description of Wadman’s campaign to engage Toby. That return gives the digression a backward connection to the plot, while the sentry-box and map turn the image’s double-ended pressure into an enacted approach. The joke depends on refusing to keep bodily desire, medical vocabulary, and military strategy in separate compartments.
