The moral person walks the straight and narrow. The immoral person is crooked, devious, bent. MORALITY IS STRAIGHTNESS maps the geometric property of linearity — the shortest distance between two points, the path that does not deviate — onto moral character. The metaphor is grounded in embodied experience: a straight path is easy to follow, easy to see ahead on, and efficient. A crooked path hides what lies ahead, wastes effort, and suggests someone has been diverted from their proper course.

Key structural parallels:

• Moral rectitude is a straight line — “rectitude” itself comes from Latin rectus (straight). A person of upright character is aligned, unbent, not leaning to one side or the other. The straight line maps onto moral consistency: the person who acts the same in public and private, who does not deviate from principle, who goes directly from intention to action without detour or evasion.
• Deviance is curvature — to “deviate” is literally to leave the straight path (Latin de- + via, off the road). Moral deviance is spatial deviance: the person who departs from the straight path of accepted behavior has gone crooked. “Perversion” maps the same way — Latin pervertere, to turn thoroughly aside. The metaphor makes nonconformity a geometric property.
• Deception is indirectness — a “straight answer” is an honest one. A “crooked” person is dishonest. The mapping is between the directness of a line and the directness of communication. The honest person goes straight from question to answer; the dishonest person curves, deflects, goes around. “Straightforward” means both geometrically direct and morally transparent.
• Moral correction is straightening — to “correct” someone is to make them straight again (Latin corrigere, to make right/straight). Reform is re-alignment. Rehabilitation “straightens out” the deviant. The metaphor provides a mechanism for moral restoration that the purity metaphor lacks: you can bend something back to straight without destroying and replacing it.
• Uprightness is vertical straightness — the moral person stands “upright.” The immoral person is “low,” “base,” or “fallen.” This variant adds a vertical axis to the horizontal straightness metaphor, connecting moral standing to the embodied experience of erect posture. Standing straight requires effort and alertness; slouching is easy and associated with negligence.

Limits

• Moral life is not a straight line — the metaphor assumes there is one correct path and all deviation is error. But genuine moral reasoning often requires navigating between competing goods, making compromises, and adapting to circumstances. A person who rigidly follows one principle regardless of consequences is “straight” by the metaphor’s logic but may be morally obtuse. The metaphor has no vocabulary for justified flexibility.
• Crookedness is not always vice — the metaphor equates indirectness with dishonesty and deviance with wrongdoing. But diplomacy requires indirectness. Tact is a form of curvature. A person who is always “blunt” and “straight” in their communication may be cruel rather than virtuous. The metaphor valorizes a particular communication style (direct, unadorned) and pathologizes others (subtle, contextual, indirect) in ways that are culturally biased.
• The metaphor naturalizes conformity — if the straight path is the moral path, then anyone who departs from the common direction is suspect. “Going straight” in criminal rehabilitation means returning to conventional behavior. The metaphor makes social conformity look like moral achievement and nonconformity look like moral failure. It cannot distinguish between a crooked swindler and a crooked innovator.
• Straightening implies an external standard — a line is only “straight” relative to a reference. The metaphor hides the question of who defines the straight path. Whose moral standard is the reference line? The metaphor naturalizes the dominant culture’s norms by making them look like geometric facts rather than social conventions.
• The metaphor conflates multiple virtues — honesty (straight talk), consistency (straight path), conformity (going straight), and courage (standing upright) are distinct virtues that the straightness metaphor collapses into one. A person can be honest but inconsistent, conformist but cowardly. The metaphor’s unifying geometry hides these distinctions.

Expressions

• “The straight and narrow” — the morally correct path, from Matthew 7:14 (“strait is the gate and narrow is the way”; later reinterpreted as “straight”)
• “A crooked politician” — dishonesty as geometric curvature (common usage since at least the 19th century)
• “He’s on the straight and level” — honest and trustworthy (common idiom, especially British English)
• “She went straight” — reformed criminal behavior as return to a direct path (common usage; “going straight” in criminal justice contexts)
• “Give me a straight answer” — honesty as geometric directness (common usage)
• “That’s a deviant act” — departure from moral norms as departure from a straight path (from Latin deviare, to turn from the road)
• “Moral rectitude” — moral correctness, from Latin rectus, straight (formal and literary usage)
• “A person of upright character” — moral virtue as vertical straightness (common usage)
• “He was bent” — British slang for corrupt, dishonest (common informal British English)

Origin Story

MORALITY IS STRAIGHTNESS appears in the Master Metaphor List (Lakoff, Espenson, and Schwartz 1991) and reflects one of the oldest conceptual metaphors in Indo-European languages. The Latin root rectus (straight) gives English “rectitude,” “correct,” “direct,” and “erect” — all carrying moral overtones that derive from the original geometric sense. The Greek orthos (straight, upright) produces “orthodox” (straight belief) and “orthopraxy” (straight practice).

The metaphor appears across unrelated language families, suggesting embodied grounding rather than mere historical accident. Walking a straight path requires intention and attention; deviation results from distraction, obstacle, or deliberate evasion. Children learn early that the direct route is the honest route and that going around (sneaking, hiding, circling) is associated with transgression. Lakoff and Johnson discuss this class of orientational metaphors in Metaphors We Live By (1980), noting that spatial orientation metaphors (up/down, straight/crooked, center/periphery) provide the foundational structure for moral reasoning.

The metaphor’s influence on legal language is pervasive. “Right” itself derives from Old English riht (straight, direct), cognate with Latin rectus. To have a “right” is to be aligned with the straight standard. “Wrong” derives from Old Norse rangr (crooked, twisted). The very vocabulary of justice encodes the straightness metaphor.
