Dichotomous Distress

Is all philosophical content expressed through either literature or abstract theoretical treatises, or is this a false dichotomy?

Depending on how we characterize literature, I think it is safe to say that the question above would be a false dichotomy. However, a closer reading of the text would indicate that Nussbaum does not offer such a dichotomy; she acknowledges many different forms through which philosophy is communicated. Her focus is primarily comparing her own advocacy (narrative form) and the most basic counterargument to her point (abstract treatises). I seems as though I was the only one in danger of forming a false dichotomy.
