2. 2015. 09. 14. The Cognitive Robinson Crusoe

3. 2015. 09. 14. The Individualistic Epistemology Assumptions and problems of „individualistic” („traditional”) epistemology: Epistemic agents are individual human beings. What are the desidered conginitve states (e.g. knowledge) and methods leading to those states (e.g. justification) ? The standards of knowledge and rationality are universal and objective. Knowledge represents the world / aims at truth (correspondence). What can an isolated subject know – should believe -- entirely on her own when her resources are her senses and the contents of her mind? In principle, an individual can know everything that can be known by a community, practically, of course, she cannot.

4. 2015. 09. 14. The social and interpersonal aspects of knowledge How do / should social processes and practices influence what we believe? the truth-value of our beliefs? the justifications we can rely on? Social Epistemology

5. 2015. 09. 14. Forms of changes: Adding assumptions (resources) and problems Replacing assumptions and problems From Individualistic to Social Epistemology

6. 2015. 09. 14. How to make social from individual epistemology? What sort of modifications of the individualistic epistemology are necessary? What kind of phenomena should be taken into consideration? And WHY? Question: Do-It-Yourself Social Epistemology

7. 2015. 09. 14. Testimony Peer agreement and disagreement Argumentation Cognitive division of labor Social norms of knowledge and rationality The role of institutions in the production of knowledge (e.g. legal processes) Etc..

8. 2015. 09. 14. Under what conditions can a testimony be relied on? Different answers: A cognitive agent can rely on it if she has further non-testimonial, direct evidence about the reliability of the speaker. (the agent’s evidence, expanded content -- individualistic epistemology) Variation: By default, she can accept them unless she has contrary evidence (defeater). (the agent’s evidence, expanded content -- individualistic epistemology) Example: Testimony, Individualistic Accounts

9. 2015. 09. 14. Under what conditions can a testimony be relied on? Different answers: The cognitive agent, s can accept what t says if t knows what she says. That is if s knows by testimony that p, then someone else should know p first. (transindividual evidence, society of knowers – social epistemology) The cognitive agent can accept a testimony if she is convinced in a rational debate that it is acceptable. (transindividual method of justification – social epistemology) New problems: what sort of soc. methods are admissible? The cog. agent can accept a testimony if she has social evidence (social indicator-properties) about the speaker’s credibility. E.g. I accept that helicobacter causes stomach ulcer, because I heard it from distinguished scientists. (social evidence – social epistemology) New problems: what sort of indicators are reliable? What social procedures can screen credibility? etc.. Example: Testimony, Social Accounts

10. 2015. 09. 14. It is a community that generates and acquires knowledge not individuals. Members of a community share beliefs, cognitive methods and practices. They rely on each other's testimony. Only community can maintain norms. Two cognitive agents: community (most fundamental), individuals. Collective epistemic agency: Are groups subjects of propositional attitudes in a non-summative sense? Difference between the beliefs of a group and its members What are the epistemic properties, methods and practices of collective epistemic agents? One More Radical Step: the Collective Agent

11. 2015. 09. 14. A radical example of social epistemology is the sociology of knowledge. („the strong program” of Bloor 1976) Example

12. 2015. 09. 14. Historical evidence: History of science and ideas shows how sociological and psychological contingencies actually played a role in what people come to believe. Theoretical arguments for the need of social (psychological) factors: Underdetermination (Duhem, Quine): Logically incompatible theories may fit all possible evidence. Theories are underdetermined by evidence: How to bridge the evidential gap? Why one theory is preferred over another? Epistemological holism (Duhem, Quine): Whole theories (together with background assumptions) are the units of test (confirmation or falsification). What claims to revise/to save? Semantic holism (Quine): Language as a whole has meaning, meanings cannot be attached to words separately. Theory-ladenness of observation: How to choose evidence? Arguments for the Sociological Approach

13. 2015. 09. 14. „…knowledge for the sociologist is whatever men take to be knowledge… beliefs which are taken for granted, institutionalized, or invested with authority…” Great variety of ideas – „…what are the causes of this variation, how and why does it change?” To EXPLAIN the production, transmission, change, structure and organization of knowledge within a particular group of people E.g.: What is believed? Who believes it and who does not? Why do they believe it? What are their sources, what are the sources of the credibility? How are these beliefs defended against doubt? Etc. The Strong Program

14. 2015. 09. 14. Methodology: Causal Explanation Social and psychological causes bringing about beliefs, to be found in: Process of socialization, transmission of culture Goals and interests of the members of the group Ways of generating consensus Rhetorical and negotiation processes Conventions Etc. Impartial explanation: both truth and falsity require explanation (not merely a sociology of error) Symmetrical explanation: the same type of cause for truth and falsity (not merely a ’sociology of error’) Reflexivity: the same explains the sociology of knowledge itself.

15. 2015. 09. 14. Sociology, social psychology, social anthropology: Methodology: Practice

16. 2015. 09. 14. Radical Socialitzation of Epistemology Individualistic Epistemology Epistemic agents are individual human beings. What are the desidered conginitve states (e.g. knowledge) and methods leading to those states (e.g. justification) ? The standards of knowledge and rationality are universal and objective. Knowledge represents the world/aims at truth (correpondence). Sociology of Knowledge Collective epistemic agent What is taken to be knowledge, how is it produced and maintained No universal standards of rationality Knowledge „represents” consensus Naturalized inquire into knowledge, the science of knowledge
