Seminar paper from the year 2019 in the subject Philosophy - Miscellaneous, grade: 2,3, Free University of Berlin (Institut für Philosophie), course: Epistemology of Emotion, language: English, abstract: In the following, I am going to analyse the effects of affective mood states on information processes. I will start by defining emotions and then taking mood into account as an essential aspect for the philosophy of mind. I will thereby explain the term "mood congruence" and demonstrate the mood-congruency effects on information processing – specifically positive- and negative moods effect. Next, the focus will lie on how an epistemology of mood and background / existential feelings could look like. In order to elaborate on my idea, I am going to examine Matthew Ratcliffe’s epistemological approach to background feelings. Subsequently, I will address the gap between epistemology of emotions and psychology which, ultimately, is responsible for a lack of understanding of the connection between affective mood states and thoughts.
