In Writing the Goodlife Ybarra details the reasons why Mexican American Literature emphasizes domestic life while seeming not to address human relationship to the environment. Ybarra reveals how environmental relationships take shape within the domestic lives of characters in Mexican American Literature, rather than in ‘wilderness’ settings as is often the case with Anglo American literature. In my own reading of Mexican American novels, I have been interested in how affect, or the emotional, also illuminates the human-nonhuman relationships within and outside of domesticity. To explore this area of interest and analysis, I call upon Teresa Brennan’s Transmission of Affect, which provides a technical language for understanding emotion. Brennan writes that the transmission of affect occurs “via an interaction with other people” [and] that the emotions of “one person, and the enhancing and depressing energies these affects entail, can enter into another” (Brennan 3). Describing the limits of her work, Brennan states that the environment in which human affective interactions occur are always a factor but, in her book, she is not “investigating environmental factors” if the word “environment” means human-nature relationships. That area of analysis falls “outside the scope of [her] book” (Brennan 8). Stepping into that opening, I bring Ybarra’s insights on ‘the good life’ together with Brennan’s technical language of affect to lay out the argument of my thesis. I build and expand understandings of domesticity, perceptions of environment, and transmission of affect with an analysis of three representative works of Mexican American Literature: Like Water For Chocolate 1989 by Laura Esquivel, So Far From God 1993 by Ana Castillo, and Bless Me, Ultima 1972 by Rudolfo Anaya. Linking analysis of affect to analysis of Mexican American domestic literary representations (that are replete with concepts of human-nonhuman relationships) highlights the intersectionality and multisubjectivity of these three important novels. I also trace Ybarra’s discussion of the “good life” to its South America roots in the concept of “buen vivir” as I explore how understanding traditional indigenous scientific literacies helps fortify Ybarra’s notion that the environmental is always at work within representation of the domestic in Mexican American literature.
