Hubristic and Authentic Pride as Serial Homologues: The Same but Different

Tracy, Shariff, and Cheng (2010) propose that human pride has two facets (hubristic pride [HP] and authentic pride [AP]) which, despite their similarities, diverge in important ways, including their evolutionary histories and functions. Put simplistically, AP emerged from HP. While AP and HP are thus homologous, HP continues to exist in humans, alongside AP. This is problematic on the most common interpretation of homology, in which an ancestral trait transforms into a derived trait, but does not remain present independently. I suggest that construing HP and AP as serial homologues (duplicated but varying traits within single organisms) solves this problem, and also resolves some of the other tensions in their account of pride as a "single" emotion with "two" facets.
