Episode Summary
Executive Summary: Michael Shermer and Richard Firth Godbehere explore the history of emotions, arguing that emotions are partly biologically evolved but heavily shaped by culture, language, and social norms. They trace changing ideas of disgust, virtue, sin, love, and fear from antiquity to modern psychology, and conclude that emotions are dynamic constructions that also matter for AI, robots, and the future of human culture.
Main Topics: Defining emotions vs. feelings, drives, and moods (Priority: 5/5): The conversation begins with the problem of defining emotion at all, distinguishing emotions from bodily drives (hunger, thirst), longer-term moods, and related states like lust, love, disgust, and pain. Disgust as an evolved but culturally shaped emotion (Priority: 5/5): Godbehere uses disgust as the clearest example of nature plus nurture: there is likely an evolved pathogen-avoidance core, but culture determines what counts as disgusting and how strongly people react. Ancient theories of soul, virtue, and emotional control (Priority: 5/5): They review Greek, Roman, Hebrew, and Christian traditions that treated emotions as linked to virtue, reason, sin, and self-control, including Stoicism, abomination, and moral discipline. Emotion theory in modern psychology and neuroscience (Priority: 5/5): The discussion covers William James, Schachter-Singer, appraisal theories, and psychological constructionism, emphasizing that bodily arousal, context, and interpretation work together. Culture, norms, and emotional regimes (Priority: 4/5): They examine how culture trains emotional expression, including witch trials, honor cultures, religious punishment, class disgust, and the role of authority and surveillance in shaping behavior. The debate over universality vs. cultural construction (Priority: 5/5): Ekman’s claim of universal facial expressions is contrasted with later work by Lisa Feldman Barrett and others suggesting emotional categories are more culturally variable than once thought. AI, robots, and the future of emotion (Priority: 4/5): The final section asks whether machines can have emotions or merely simulate them, and whether global digital culture may eventually homogenize emotional expression.
Key Arguments: Emotions are not purely innate or purely cultural; they emerge from interaction between evolved bodily responses and learned interpretation. Disgust likely evolved to protect against pathogens, but cultures teach people what objects, foods, and behaviors count as disgusting. Language reshapes emotion categories: a single translated term can flatten historically or culturally distinct emotional concepts. Ancient philosophies and religions framed emotion as a moral issue, often emphasizing virtue, restraint, and the management of desire. Modern emotion research increasingly supports contextual and constructionist views over simple universal-face models. People can be morally and emotionally manipulated by reclassifying others as disgusting, sinful, or nonhuman, which helps explain witch hunts, slavery, and genocide. Human judgment depends on emotion; purely rational decision-making is unrealistic and often impaired when emotion is absent. AI may simulate emotional behavior, but current systems do not obviously have subjective feeling or “wanting,” making true machine emotion difficult to verify.
Data Points: Definitions of emotion in the literature: 167 definitions (reported in a 1992 meta-analysis) - Used to illustrate how unsettled the concept of emotion remains in psychology and philosophy. Greek soul model: 3 parts - Godbehere describes Greek traditions as dividing the soul into a life-force, sensitive soul, and rational soul. Basic emotions in Ekman’s original model: 6 - Happiness, sadness, surprise, disgust, anger, and fear were presented as universal facial emotions. Book chapter count referenced: 14 emotions in later Ekman framing - Shermer notes Ekman later expanded his view beyond six emotions. Childhood emotion recognition example: Up to age 8 - Godbehere mentions research suggesting some children cannot reliably distinguish fear and disgust faces until around this age. Facial-expression study sample framing: Japan, America, Germany, Papua New Guinea - Ekman-style cross-cultural research used these settings to test universality of expression recognition. Sexual-request experiment response: About 50/50 - When asked for a date, both sexes accepted at roughly even rates in the example Shermer recounts. Sexual-request experiment response: About 80/20 - When asked to go back to an apartment, the response shifted strongly, especially by gender. Sexual-request experiment response: About 90% to zero - When directly asked for sex that night, acceptance collapsed, especially among women. Horror and physiological response: 10 seconds - Shermer describes feeling fear after seeing a rattlesnake only after the immediate jump reaction, illustrating delayed appraisal. Emotion response duration: Short-lived - They repeatedly describe emotions as brief blasts compared with longer moods. Mood vs. emotion: Long-term vs. brief - Sadness is described as a mood, while anger is framed as a quick emotion. Historical time span discussed: 200 years - Godbehere cites English history as showing multiple changing versions of disgust within a relatively short time.
Pivotal Quotes: "Reason is and ought only to be the slave of the passions" — David Hume (quoted by Michael Shermer): Used to argue that reason guides goals only after emotion supplies motivation and value. "There is a big war within emotion research about this right now, but I like to sit in the middle and go, hey, you're both wrong and right." — Richard Firth Godbehere: Summarizes his position that emotions are both biologically grounded and culturally shaped. "We can tell you how they used to talk about how they felt and how they used to paint their feelings or put their feelings in poetry or whatever, but we can't actually get inside their heads." — Richard Firth Godbehere: Explains the limits of historical work on emotions and why historians study expression rather than direct access to inner experience.
Implications: Listeners should expect emotion to be seen less as fixed biology and more as a flexible system shaped by culture, history, and context. The same framework affects psychology, morality, politics, and debates about whether AI can truly feel.
