Conatus → Emotions

Discover how Spinoza derives all human emotions from one basic drive: the striving to persist in being. See how joy, sadness, and desire are not random feelings but expressions of your fundamental nature.

Steps

Setup

  1. Proposition

    The order of ideas and things is the same

    Mind and body are parallel expressions of one reality, never interacting as separate domains.

  2. Proposition

    The human mind is the idea of the human body

    Emotion is always embodied — the mind feels what the body undergoes because the mind is the idea of the body.

  3. Proposition

    Mind does not move body; body does not move mind

    There is no causal arrow from body to mind or mind to body; emotional life must be understood within parallelism.

  4. Proposition

    Activity from adequate ideas; passivity from inadequate ideas

    The active/passive distinction in emotion tracks the adequate/inadequate distinction in cognition.

Demonstration

  1. Proposition

    Nothing is destroyed except by an external cause

    Self-destruction is impossible; every threat to a thing's existence comes from outside.

  2. Proposition

    Contraries cannot coexist when one can destroy the other

    A thing opposes whatever could destroy it; contraries are structurally expelled.

  3. Proposition

    Everything endeavours to persist in its being

    Conatus — the striving to persist in being — is the fundamental drive from which all emotion will be derived.

  4. Proposition

    Conatus is the actual essence of the thing

    Conatus is not a property of essence; it is essence itself, understood dynamically.

  5. Proposition

    Conatus involves indefinite duration

    Conatus has no built-in endpoint; mortality comes only from external causes.

  6. Proposition

    The mind is conscious of its own striving

    Conscious striving is the subjective root of all emotional life.

Consequence

  1. Proposition

    Appetite and desire

    Desire is conscious appetite — the first primitive affect, and the origin of all valuation.

  2. Proposition

    The mind affirms the body's existence

    The mind's deepest structural commitment is affirming the body's existence.

  3. Proposition

    Changes in bodily power alter mental power

    Emotion is the mind's awareness of increases and decreases in the body's power of acting.

  4. Definition

    Joy, sadness, desire: the three primary affects

    All emotions are compositions of three primitives: joy (power up), sadness (power down), and desire (conscious striving).

  5. Bridge

    Complex emotions as compositions of the primitives

    Every emotion can be parsed as a primitive affect (joy, sadness, desire) combined with a type of idea (adequate or inadequate, of self or other, of past, present, or future).

Recap

  1. Recap

    Passive affects from external determination; active affects from adequate causation

    The path from emotional bondage to freedom runs through the transformation of inadequate ideas into adequate ones — turning passions into actions.

Concepts covered

You now see how all emotions trace back to conatus and the increase or decrease of your power. Passive affects trap you; active affects free you. This is Spinoza's psychology.
