Imitatio Affectuum

In the AI Story

The mechanism explains why the AI discourse rarely changes minds through evidence. A person who feels inadequate after reading a triumphalist post does not understand that her inadequacy is produced by a specific mechanism — the imitation of affects operating through perceived similarity — rather than by a genuine assessment of her own capabilities. Her inadequacy feels internal. It is partly external. The passion feels authentic. It is partly absorbed.

The triumphalist narrative infects the discourse with uncritical excitement. The elegist narrative infects it with unconsoled grief. The Luddite response infects it with professional anxiety. Each narrative spreads through the mechanism Spinoza identified, and each produces affects that are experienced as authentic assessments of the situation rather than as passions produced by contagion. The silent middle, paradoxically, is the population most aware of the contagion — which is partly why it cannot speak in the voice the discourse rewards.

The remedy, as with every passion in Spinoza's framework, is not quarantine but understanding. The person who understands why the triumphalist's excitement is contagious — who can identify the imitation mechanism, the perceived similarity, the specific pathway from the post to her own feeling of inadequacy — has transformed the contagious passion into an adequate idea. The passion does not disappear. But it loses its power to drive her behavior without her comprehension.

The mechanism compounds with the architecture of social media platforms that algorithmically amplify affects most likely to produce engagement. The imitation of affects was a local phenomenon in the seventeenth century, operating through face-to-face encounter. It now operates at a speed and scale Spinoza could not have anticipated, through engagement-optimized systems that select specifically for affectively contagious content. This is contagion raised to industrial power, and it shapes the experience of the AI transition for everyone inside the discourse it produces.

Origin

The doctrine appears in Ethics III, Proposition 27: 'If we imagine a thing like ourselves, toward which we have had no affect, to be affected with some affect, we are thereby affected with a like affect.' Spinoza develops the consequences through Propositions 28–35, showing how imitation of affects produces the entire landscape of social emotions — emulation, ambition, envy, compassion, benevolence.

The mechanism anticipates contemporary research on emotional contagion and mirror neuron systems. Elaine Hatfield's work on emotional contagion in the 1990s, and subsequent neuroscience of shared affect, operates within frameworks Spinoza formalized three centuries earlier. The social media era has made the mechanism newly visible at civilizational scale.

Key Ideas

Below awareness. The imitation operates automatically through perceived similarity and cannot be prevented by resolve; it is a structural feature of social cognition, not a choice.

Inadequacy as contagion. The specific feeling of inadequacy produced by reading about others' accomplishments is partly a contagious affect, not only an accurate self-assessment.

The discourse as field. The AI conversation is not an exchange of analyses but a field of contagious passions; triumphalism, elegy, and resistance each spread through the mechanism.

Amplification by algorithm. Engagement-optimized platforms select for affectively contagious content, raising a seventeenth-century mechanism to industrial scale.

Understanding as remedy. The passion cannot be quarantined, only comprehended; tracing the contagion to its mechanism transforms the passion from a force that drives behavior into an adequate idea one can navigate.
