Part 8/12:
Philosophical Foundations: Why Morality and Definitions Matter
A recurring theme is the critique of the relativistic, postmodernist view that "truth" and "morality" are subjective or unknowable. The speaker dismisses the notion that good and bad lack objective definitions—arguing instead that humans have always navigated morality through heuristics, feedback, and adaptive behavior.
They cite Patricia Churchland’s Brain Trust to reinforce that morality rooted in evolutionary biology, psychology, and neuroscience is relatively straightforward. Our moral judgments are the result of biological imperatives and social feedback, not abstract philosophical ideals.
