6 Einführung Bild und Erkenntnis Einige Probleme Fazit IntroductionEpistemic FuntionsRhetoricConclusion 6 Pictures as empirical basis In empirical research, causally created pictures are particularly important. They serve to augment perception in order to verify the existence of objects or events. When pictures are used indexically as a measuring instrument, precise calibration must be ensured (i.e. authorization/authentification). Epistemic Functions

8 Einführung Bild und Erkenntnis Einige Probleme Fazit IntroductionEpistemic FuntionsRhetoricConclusion 8 Pictures in contexts of justification Pictures can depict complex issues schematically. Here, their epistemic contribution arises from the illustration of an argumentation. Pictures can function also as visual arguments. In contexts of justification, visual arguments require a precise (usually verbal) explanation. Epistemic Functions

13 Einführung Bild und Erkenntnis Einige Probleme Fazit IntroductionEpistemic FuntionsRhetoricConclusion 13 Pictures in contexts of discovery In epistemic contexts of discovery, pictures often fulfill the function of analogies (as do metaphors). Pictures allow for the transfer of complex structures from a field theoretically well- founded to a field yet unexplored. As analogy models, they also influence our abstract conceptual views. Epistemic Functions

15 Einführung Bild und Erkenntnis Einige Probleme Fazit IntroductionEpistemic FuntionsRhetoricConclusion 15 The basic problem: Pictures and knowledge 1 Knowledge is true and justified opinion. Truth is a property of statements / propositions. True opinions (knowing that) presuppose concepts. Justification is a communicative activity. Rhetoric

16 Einführung Bild und Erkenntnis Einige Probleme Fazit IntroductionEpistemic FuntionsRhetoricConclusion 16 The basic problem: Pictures and Knowledge 2 In contrast, the essential function of pictures is illustration respectively visual characterization. In terms of communication theory, this function is comparable to predication. Thus, reference is principally problematic. Problem of selection Rhetoric

18 Einführung Bild und Erkenntnis Einige Probleme Fazit IntroductionEpistemic FuntionsRhetoricConclusion 18 Pictures and idealization An important subfunction regarding the epistemic use of images is idealization. Analogy models are idealizing representations. Idealization corresponds to an emphasis of particular aspects / views. Idealization is a rhetorical figure that possesses a certain closeness to the conceptual. Rhetoric

20 Einführung Bild und Erkenntnis Einige Probleme Fazit IntroductionEpistemic FuntionsRhetoricConclusion 20 Conclusion Pictures can assume epistemic functions in different ways. However, the quality of an epistemic function always depends on the respective contextual (often linguistic) embedding, as well. Accordingly, pictures can direct knowledge, but through skillful recontextualization, they can also ideologically distort it. Conclusion
