Part IIThe Nature of Concepts Part II of How to Design an Emotion: The Deconstruction and Computation of Emotional Meaning from First Principles

Abstract

In Part II, I pay the debt Part I leaves: I cannot say what an emotion is until I know what an idea is. I define an idea as a unit of meaning that holds one or more claims you can call true or false. I then put modern concept theory to the test, beginning with Lisa Feldman Barrett’s Theory of Constructed Emotion. I grant that it explains variety, context, and culture better than the classical view. Yet a word names a group; it cannot admit members, and agreement cannot say when a community gets anger wrong. I call the wider error the misappropriation of the concept: sorting and prediction take over an authority that belongs to identity conditions. Against the false choice between universal essences and constructions of the moment, I propose constraint without universality. I also refuse the forced choice between classical and prototype theories, because each answers a different question. What is shared: concepts have a core, and typicality is real. What is new: a strict four-layer order, a separate goal layer, and a test that makes the order inspectable. I call the result the Theory of Constrained Identity. A concept constrains, an instance realizes, a category groups, and goals steer the groupings from above. Five rules keep identity stable while instances vary. I draw the architecture in the Unified Modeling Language, run it in C#, and apply it to anger. Part II closes by asking how a concept comes to mean anything beyond itself.

Key concepts

Idea

“An idea, as I define it, is a unit of meaning that holds one or more claims you can call true or false.” (Chapter 2)

Identity conditions

“The constraints, specified at a concept’s constraint layer, that an instance must satisfy to count as admissible.”

Constraint without universality

“A concept states the conditions an instance must meet within a system, for an agent, in a context.” (Chapter 3)

Misappropriation of the concept

“I call this the misappropriation of the concept: downstream operations grab an authority that belongs upstream, borrow the work of identity conditions, and deny any debt.” (Chapter 4)

Theory of Constrained Identity

“It separates four functions: conceptual identity (constraint), instantiation, categorization, and goal-directed evaluation.”
