16 Probably the most basic form of involvement of emotions in the formation of knowledge is what people refer to as "passion of knowledge." Not only desire is involved in wanting to discover truth in scientific and other contexts, but also a form of literal passion for knowledge. I interpret this passion not as one, but as a myriad of emotions that are usually implicated in processes of formation of knowledge: hope for the discovery of truth, disgust at fallacious arguments, surprise when something happens that conflicts with prior theoretical expectations, etc. There is a diversity of emotions involved in cognitive processes: hope, fear, pride, admiration, joy, contempt, etc. All these emotions, along with several sorts of practical interests, play an important role as practical stimuli for the generation of knowledge. Israel Scheffler shows "how cognitive functioning employs and incorporates diverse emotional elements". (SCHEFFLER. In Praise of the Cognitive Emotions. In Praise of the Cognitive Emotions. New York/London: Routledge, 1991. p. 3).
