What It Brings

We talk about psychological causation as if invisible hands were shoving us around. Desire pulls, fear pushes, guilt weighs down, ambition drives forward. Lakoff and Johnson treat this as part of their broader analysis of causation in Metaphors We Live By: our prototype of causation is direct physical manipulation, and psychological causation inherits that structure. The mind becomes a space in which forces act on a person-object.

Key structural parallels:

Compulsion as physical pushing — “She pushed me into it.” “I was driven to succeed.” “Something compelled me.” Psychological motivations are experienced as external forces applied to the self, as though another agent were physically moving you. This preserves the force-dynamic structure of causation: there is an agent (the emotion or motive), a patient (the self), and a vector (the direction of action).
Resistance as physical counterforce — “I resisted the temptation.” “He held back his anger.” “She fought the urge.” The self can push back against psychological forces, generating the same tension structure as two physical objects in opposition. Willpower is counterforce.
Attraction as pulling — “I was drawn to the idea.” “The offer was magnetic.” “She gravitated toward philosophy.” Desire and interest are mapped onto gravitational or magnetic pull — forces that act at a distance without contact, which is apt because psychological attraction operates without physical touching.
Overwhelm as being knocked down — “It hit me hard.” “I was floored.” “The news bowled me over.” When psychological force exceeds resistance, the result is the same as in physical force dynamics: the patient is displaced, knocked off balance, or flattened.
Pressure as sustained force — “I’m under a lot of pressure.” “The stress is crushing me.” “He cracked under the strain.” Ongoing psychological states map onto continuous applied force, with the structural implication that the patient can endure up to a threshold and then breaks.

Where It Breaks

The agent is often missing — physical force has a clear source: a hand, a wind, a weight. Psychological forces frequently have no identifiable agent. “Something pushed me to do it” gestures at a source that cannot be located. The metaphor demands a force-applier, so we fabricate one — “my conscience,” “my demons,” “a voice inside me” — splitting the self into agent and patient. This is structurally useful but ontologically strange: who is pushing whom?
Direction is ambiguous — physical forces have vectors: magnitude and direction in space. Psychological forces rarely have clear spatial direction. “Driven to succeed” uses forward motion, but “driven to drink” uses the same forward frame for what is conceptualized as decline. The spatial mapping is inconsistent because psychological states do not occupy Euclidean space.
The metaphor makes internal states external — by framing psychological causation as force applied to a patient, the metaphor positions the self as passive and the emotion or motive as an external agent. This creates a systematic alibi: “I was pushed into it” deflects responsibility in a way that “I chose it under internal conflict” does not. The metaphor makes agency hard to assign.
No conservation law — physical forces obey Newton’s third law: every action has an equal and opposite reaction. Psychological forces do not. Resisting temptation does not generate a proportional counterforce in the temptation. The symmetry that makes the physical metaphor coherent breaks at the structural level.
Threshold effects are unpredictable — in physics, you can calculate when a force will overcome resistance. In psychology, the “cracking point” is not a function of measurable quantities. The metaphor imports an engineering notion of stress and yield that makes psychological collapse seem more predictable and mechanical than it is.

Expressions

“She pushed me into it” — psychological compulsion as physical shoving
“I was drawn to the idea” — intellectual interest as gravitational pull
“He was driven by ambition” — sustained motivation as propulsion
“I resisted the temptation” — self-control as physical counterforce
“The news hit me hard” — emotional impact as physical collision
“I was floored by the revelation” — shock as being knocked to the ground
“She fought the urge” — internal conflict as physical struggle
“I’m under a lot of pressure” — sustained stress as applied force
“He cracked under the strain” — psychological breakdown as material failure under load
“Something pulled me back” — hesitation as restraining force

Origin Story

Lakoff and Johnson discuss psychological forces as part of their broader treatment of causation in Metaphors We Live By (Chapters 6 and 14). They argue that our understanding of causation is not a single logical relation but a cluster of metaphors centered on the prototype of direct physical manipulation. PSYCHOLOGICAL FORCES ARE PHYSICAL FORCES is one extension of this prototype: the internal experience of being motivated, compelled, or restrained is understood through the same force-dynamic schemas that structure our experience of pushing and pulling physical objects.

Talmy’s force-dynamics framework provides the linguistic scaffolding: causation in language is fundamentally about forces and barriers, and psychological causation is no exception. The metaphor is grounded in the correlation between emotional states and bodily experience — fear triggers the startle reflex (a physical force response), anger produces muscular tension, desire produces forward-leaning posture.
