Learning: Early Beginnings to Modern Times Chapter 3 1 Epistemology Epistemology is a branch of philosophy that deals with the nature of knowledge and seeks answers to questions below. Epistemology is a philosopher’s way of looking at learning. What is knowledge? What are the limits of knowledge? What are the origins of knowledge? How is knowledge acquired (learning)? 2 Socrates Theory of Knowledge Knowledge is acquired through disciplined conversation (dialectics). filipinaatheist.files.wordpress.com Disciplined conversation requires ideas be consistently clarified through dialogue. (470-399 BC) 3 1 Problems 1. Conversations, in defining ideas can lead to confusions rather than clarity. 2. Such confusions arise due to different perspectives people may hold especially with abstract definitions, that are hard to define in the first place. People stick to particular cases when defining abstract ideas, e.g., beautiful flower and not the idea of beauty. 4 Plato Innateness of Knowledge Plato student of Socrates, believed in the innateness of knowledge. Human mind possessed www.poems.net.au knowledge. To acquire knowledge, humans must reflect on the contents (447-327 BC) of the mind. 5 Plato Innateness of Knowledge Self-exiled himself to Italy after Socrates execution and joined Pythagoras. Pythagoras suggested that www.poems.net.au universe was dualistic. Plato proposed mind-body dualism, and said that mind affected (447-327 BC) the body, but the body could not affect the mind. 6 2 Aristotle Knowledge through Experience Aristotle student of Plato, believed that sensory information was the basis of all knowledge (experience). www.martinfrost.ws Attainment of knowledge was through mind, which interconnects ideas. All forms (384-322 BC) of sensory information result in mental ideas. 7 Aristotle Aristotle’s Laws Laws of Association a. Similarity (lemon-lime) b. Contrast (night-day) c. Contiguity (table-chair) www.martinfrost.ws Law of Frequency If two events are experienced repeatedly, presentation of (384-322 BC) one will lead to the recall of other. 8 Law of Association 9 3 Comparison Plato (Nativist) Aristotle (Empiricist) Knowledge is innate. Knowledge is acquired through senses. Plato & Aristotle (Rationalists): Mind acquires knowledge because it is a reasoning organ. Plato thought mind was Aristotle thought mind associated with the was associated with the brain. heart. 10 Rene Descartes Interactive Dualism www.img.tfd.com Like Plato, Descartes believed, mind possessed innate ideas.

Beginnings to modern S-R psychology. 11 Thomas Hobbs Sense Impressions Hobbs was an empiricist and an associationist, like Aristotle. Believed that sense impressions are the basis of www.raffiniert.ch knowledge. Proposed stimuli either help (1588-1679) or hinder vital functions of the body. 12 4 John Locke Tabula Rasa Locke was an empiricist and completely against the idea of innate ideas. Mind is blank slate (tabula www.artunframed.com rasa) at birth and experience writes on it. (1632-1704) 13 John Locke Qualities Characteristics of the physical world can be primary, those that form accurate mental www.artunframed.com representations e.g., size, weight, quantity, solidity, extension etc., and secondary that cannot e.g., (1632-1704) color, odor, sound, atoms, molecules, airwaves etc. 14 George Berkeley Secondary Qualities Berkeley an empiricist, suggested that contents of the mind are derived from experience. upload.wikimedia.org No primary qualities, all secondary qualities.

Hume an empiricist- associationist, suggested that chaosandoldnight.files.wordpress.com we cannot be sure of the physical world and the ideas it generates. Because of secondary qualities of sensory information. Mind = stream of ideas, (1711-1776) memories, images, associations, and feelings. 16 John S. Mill Complex Ideas Revised Hobbs and Locke empiricism and associationism. All ideas do not reflect upload.wikimedia.org sensory stimulation. Complex ideas may not be based on combination of (1806-1873) simple ideas e.g., red, blue and green gives white light. 17 Immanuel Kant Nativist & Empiricist Kant was both a nativist and an empiricist, revived Plato’s rationalism. Attempted to save www.markrietmeijer.nl philosophy from Hume’s criticism and removed the impractical aspects of rationalism and empiricism. (1724-1804) 18 6 Immanuel Kant Sensory Experiences Sensory experience (ideas & concepts) are manipulated by reasoning. However, meaningfulness is generated www.markrietmeijer.nl by sensory experiences and innate categories. (1724-1804) 19 Immanuel Kant Innate Categories Proposed 12 Innate categories of thought. Categories of Quantity Categories of Relation • Unity • Substance and accident • Plurality • Cause and effect www.markrietmeijer.nl • Totality • Reciprocity (agent and patient) Categories of Quality • Reality Categories of Modality • Negation • Possibility—Impossibility • Limitation • Existence—Non-existence • Necessity—Contingency (1724-1804) 20 Thomas Reid Faculty Psychology Reid was an empiricist and a nativist, like Kant. Proposed even greater number of innate categories www.martinfrost.ws (27 in all) and founded Faculty Psychology. (1710-1796) 21 7 Franz J. Gall Phrenology Faculties (categories) housed in different parts of the brain. Founded the area of phrenology. The idea that portrait.kaar.at skull bumps and dips represent degrees of development of faculties. (1758-1828) 22 “Skull Bumps” Phrenology Faculties became stronger with practice, and weaker without it. A “mental muscle” approach called formal etc.usf.edu discipline.

(1832-1920) 28 Wilhelm Wundt School of Voluntarism Humans can selectively attend to elements of thought (apperception) and can arrange them in a www.psych.upenn.edu number of ways (creative synthesis). (1832-1920) 29 First Psychology Lab Wundt founded the first psychology lab in Leipzig, Germany (1879) and devised introspection as a method to study the elements of thought. www.dgps.de 30 10 Edward B. Titchner School of Structuralism Student of Wundt. Carried out experiments on mind at Harvard. organizations.uncfsu.edu Used introspection to study the elements of mind: sensation, images and feelings. (1869-1927) Studied laws of association between mental elements. 31 Charles Darwin Evolution & Learning Darwin was an empiricist and an associationist, proposed the theory of evolution, which www.biografiasyvidas.com affected modern science and religion. Learnt (as opposed to innate) behaviors in man and animal were a predominant way to (1809-1882) greater environmental adaptability. 32 William James School of Functionalism Consciousness (mind) cannot be divided into elements. It flows like a stream (James, www.philosophyprofessor.com 1901). Function of consciousness is to make the individual adapt to the environment. (1842-1910) 33 11 John B.
