BLOCK 1 Knowledge is a relation between two beings: the known and the knower. Through this relation the knowing subject (knower) opens oneself to the world. The one who knows leaves oneself and turns to the surrounding world. However, in knowledge one returns to oneself as the known being ‘penetrates’ into the subject in some way since knowledge takes place not outside, but inside the subject. In knowledge an object makes itself present to the subject. The known ‘reproduces’ itself in the knower, e.g., when the colour blue is known, the blue of the thing penetrates into the subject. This process takes place immaterially. For we cannot observe the intentional presence of colour in a subject, as the blue colour in a flame is observed. The intentional presence is an unobservable and absolutely private fact. Epistemology is the theory of human knowledge in so far as it contemplates on the origin, process, nature, structure, validity and truth value of human knowledge. This block, consisting of four units, deals with the definition, nature, history of epistemology and various epistemological concepts. Unit 1 begins with the Definition and Nature of Epistemology. It studies the concept of knowledge along with its traditional definitions and probes into how knowledge is different from belief. One of the important movements that has challenged epistemology is skepticism and it is in the face of this challenge that epistemology has developed. Rationalism and empiricism are the theories that have been put forward to discuss the origin of knowledge. Unit 2 deals with a Brief History of Epistemology. The discussion has begun from the very ancient time itself, period of Ancient Greek Philosophy, Medieval Epistemology, Rationalism, Empiricism and Synthesis in Kant, Post-Kantian Epistemology, and Phenomenological Epistemology of late19th Century, Realism of 20th century and recent Developments in Epistemology. Unit 3 studies some of the Basic Concepts and Assumptions. Epistemology is a science which deals with knowledge and hence it has some important concepts like belief, justification, truth, certainty, skepticism and foundationalism which need to be clarified. Unit 4 highlights the Theories of Truth put forward by various thinkers. This unit begins by disclosing the problem of truth that has been discussed for a long time. Along with this we have the nature and criteria that tells what truth is, the various perspectives on truth, classical theories of truth, and the importance of studying the concept of truth. This block becomes introductory note to what is to follow in the following units and makes us well equipped with the terminologies that are used in this discipline. Notions like belief and truth which have a highly ambiguous connotation are clearly dealt in these units. BPY 010 EPISTEMOLOGY (4 CREDITS) COURSE INTRODUCTION Epistemology is one of the main branches of systematic philosophy. It is concerned with the nature, sources, and limits of valid and true knowledge. The subject matter of epistemology is knowledge itself. The term ‘knowledge’ has a number of connotations, but here in philosophy we are concerned with propositional knowledge, that is, knowledge that such-and-such is true. It begins with some of the basic questions like, ‘what is knowledge,’ ‘what are the sources of knowledge?’ ‘What is the certainty of the knowledge that one has?, etc. All these questions were taken up for discussion from the ancient times and a number of approaches and views have been put forward. It forms one of the bases of many other disciplines because all other disciplines have something to do with cognition and even the modern computer which uses artificial intelligence in some way resembles the human’s capacity to use knowledge. So this field of philosophy is an area of frequent discussion even to this day and many thinkers contribute to its growth. This course is broadly divided into Four Blocks with 16 units. Block 1 introduces the term ‘epistemology’. This block highlights the definition, nature, brief history of epistemology, including the basic concepts and assumptions and the theories of truth. Block 2 deals with various sources of belief. Beginning with perception, which is very common, this block deals with hermeneutic or constructivist view of perception, inference and testimony. Block 3 is on the Methods and Justification of Knowledge. Other subtopics in this block are Metaphysical Method of Aristotle and Aquinas, Foundationalism and Coherentism, Introducing some complexity, and Popperian Method and Naturalized Epistemology. 1 Block 4 probes into the Knowing Subject. The block brings to light the various views like the mirroring mind, revolt against the mirroring mind, not mirrors but maps, critical appraisal and synthesis contributed by various philosophers. These various topics form the core of Epistemology and make a detailed study of one of the important branches of Philosophy 2 UNIT 1 DEFINITION AND NATURE OF EPISTEMOLOGY Contents 1.0.

OBJECTIVES The main objective of this Unit is to introduce you to epistemology and to determine its nature and scope. We will explore what it means to say that someone knows, or fails to know something and how much do we, or can we know. We will see both an etymological and traditional definition of knowledge, together with a general understanding of the term ‘to know’. We shall also briefly cover different attitudes with regard to our ability to know reality. Finally, we will conclude with the importance of epistemology in human life. Thus by the end of this Unit you should be able: • To give a definition of knowledge; • To differentiate between knowledge and belief; • To know the role of scepticism as an adversary to knowledge; • To know the role of reason and the senses in acquiring knowledge; 1 • To know the scope of epistemology; • To know the importance of epistemology in comprehending the world we live in. 1.1. INTRODUCTION Aristotle begins his work Metaphysics with the observation ‘All men by nature desire ‘to know.’ Kant raises the question ‘What can I know?’ The drive to know is fundamental to being human. Epistemology tries to fulfil this desire. Epistemology is the branch of philosophy that deals with the nature, origin and scope of knowledge. Epistemology focuses on our means of acquiring knowledge and how we can differentiate between truth and falsehood. The term ‘epistemology’ was coined by the Scottish Philosopher James Fredrick Ferrier (1808-64). It comes from the Greek word ‘episteme’ (knowledge) and ‘logos’ (theory or science). It addresses the following questions: What is knowledge? What can we know? How can we know it? How is knowledge acquired? Can knowledge be certain? Is there a distinction between knowledge and belief? What is the scope of knowledge? Why do we believe certain claims and not others? 1.2. EXPLAINING THE CONCEPT OF KNOWLEDGE Before we go into the traditional definition of knowledge we should know what ‘to know’ means. An analysis of the concept of knowledge has to be done to see how this term is used in everyday language. Expressions such as ‘know that,’ ‘know how,’ ‘know why,’ ‘know him,’ ‘know where,’ and ‘know whether,’ needed to be examined in detail. In the English language the word ‘knowledge’ is used in a variety of senses. It is used in the sense of ‘being acquainted with’ or ‘being familiar with’. We commonly speak of ‘knowing’ a person, place or a thing in this sense. We also use it in the sense of ‘being aware’ of something. Sometimes it is used as an 2 expression of ‘psychological conviction’. Philosophers give multiple senses of knowledge such as: i. ‘knowing that,’ ii. ‘Knowing which,’ iii. ‘Knowing how,’ iv. ‘Knowing what,’ v. ‘knowing what it is like.’ Plato, used the term techne or skill for ‘knowing how’ (to do something), and the term episteme for a more forceful kind of knowledge in which claims can be true or false. There is a difference between ‘knowing that’ and ‘knowing how’. ‘Know how’ is used to refer to a kind of skill or ability, such as knowing how to swim. Here even if one knows what it is, he may not be able to explain the rules or laws of a skill. However, the expression, ‘know that,’ in contrast, seems to denote the possession of a specific piece of information, and the person who has knowledge of this sort generally is able to convey this knowledge to others. Philosophers are mainly concerned with ‘knowing that’ something is the case and it is in this sense of the word that a claim is either true or false. This meaning of ‘to know’ is called ‘propositional knowledge’. Epistemologists from ancient Greeks to the present have focused on propositional knowledge—that is, the ‘knowing that’ kind of knowledge. Propositional knowledge encompasses ordinary perceptual knowledge, scientific knowledge, geographical knowledge, ethical knowledge, mathematical knowledge, religious knowledge, self-knowledge, and knowledge about any field of study whatever. A proposition is a declarative sentence which purports to describe a fact or a state of affairs, such as ‘Dogs are mammals,’ ‘2+2=7.’ A proposition may be true or false; that is, it need not actually express a fact. Propositional knowledge, then, can be called ‘knowing-that.’ Statements of propositional knowledge are properly expressed using ‘that’-clauses, such as ‘He knows that Delhi is in India.’ Not all sentences are propositions. For example, ‘what is the time?’ This sentence is not a proposition because one cannot ask whether what the sentence expresses is true.
