Introduction of Epistemology-Phil 101

Explore epistemology as the theory of knowledge, tracing Western philosophy from ancient Greek thinkers through the medieval and modern eras, including the two branches within epistemology and Kant's critical epistemology.

Explore epistemology as an introduction to the concept of knowledge, examining how the word knowledge is defined and discussed in philosophical inquiry.

Explore the distinction between assertion and proposition, truth values, and propositional attitudes like belief; learn how truth depends on correspondence with reality and speaker's belief, leading to knowledge.

Explain Plato's tripartite definition of knowledge as a true belief with justifiable ground, outlining the necessary conditions—truth, belief, and justification—and noting that false beliefs are not knowledge.

Explore the Gettier problem challenging the tripartite definition of knowledge by presenting justified true beliefs that fail due to luck, as in the Smith and Jones coin scenarios.

Explore Gettier’s second scenario and its challenge to tripartite knowledge. Smith forms a justified true belief that either Jones owns a Ford or Brown is in Barcelona, yet lacks knowledge.

Examine disjunctive proposition in epistemology by showing a disjunction is true if part is true, using Delhi is the capital of India or the Moon is made of green cheese.

Present responses to avoid the Gettier problem within the tripartite definition of knowledge, emphasizing justified true belief, no false claims, reliable methods, and virtue epistemology.

Explore the origin of knowledge by examining how knowledge arises and why philosophers investigate its nature, tracing its central role in the history of epistemology.

Compare rationalism and empiricism, contrasting innate ideas and a priori knowledge with tabula rasa shaped by sense experience, and examine how mind and experience justify beliefs.

Examine how the pre-socratic era challenges the certainty of knowledge by questioning belief in external objects and senses, arguing we should claim knowledge only when absolutely certain.

Philosophers debate what constitutes certain knowledge, contrasting rationalists who derive it from axioms and theorems with empiricists who rely on sense experience as the foundation of ordinary knowledge.

Trace the history of epistemology from the pre self-critique era to Kant, noting Copernican revolutions, transcendental idealism, and the synthetic a priori bridging rationalism and empiricism.

Explore the pre-socratic era's view on change and motion, the sophists' claim of absolute truth, and how Socrates linked virtue to knowledge for the good life.

Plato's epistemology, shaped by Socratic debates, argues that knowledge is not empirical and comes from divine insight, with the forms grounding certainty.

Plato's epistemology asserts that knowledge cannot come from changing experience; only reason can grasp the unchanging, perfect forms, while sensible things remain imperfect copies and only yield opinion.

Plato's epistemology comprises two parts: the nature of unchanging objects—the forms or world of forms—and an analysis of how those objects can be known.

Reveal how Plato's allegory of the cave depicts prisoners chained to a wall, experiencing only shadows through sense perception. The image contrasts limited knowledge with the outside world.

In the allegory of the cave, prisoners mistake puppets' shadows lit by fire for reality, and freedom reveals real objects and the sun as the ultimate source of knowledge.

A philosopher discovers true knowledge through a painful intellectual process that rejects the familiar world, climbs from the cave into reality, and apprehends unchanging objects to acquire knowledge.

Explore a four-step journey from imprisonment in the cave and its shadows to release, ascent to the world of ideas, and return to enlighten others, toward the Sun of knowledge.

Explore Plato's threefold distinctions: knowledge, ignorance, and belief, as knowledge rests on reason and ideas or forms, while ignorance is imagination; compare with Vedanta's reality culminating in Brahman.

Explore Plato's epistemology, where forms are the objects of true knowledge, and reason and dialectic reveal the necessary and sufficient conditions for being a sister, female and a sibling.

Explore Plato's view that knowledge cannot come from sense experience, which yields only imperfect appearance, and that true knowledge resides in the realm of forms accessible through reason and dialectic.

Explore Plato's idea that knowledge is justified true belief, with attention to false beliefs and the need for justification. Consider the Gettier challenge that questions this view.

Explore how Aristotle links knowledge with metaphysics through his doctrine of the soul, noting that all living beings have a soul, but only humans possess intellect.

Aristotle argues knowledge concerns universals embedded in particulars and rejects Plato's separate forms, proposing that substances combine form and matter where form defines kind.

Explain knowledge as the soul's reception of forms, the unmoved mover as the first cause, and the intellect's matter and form with the active intellect.

Aristotle outlines multiple means of knowledge, from senses and common sense to images, memory, imagination, and finally intellect, where concepts and judgments form knowledge.

Explore Aristotle’s view of knowledge as the apprehension of essential connections in judgment. Link sense experience, classification into genders and species, and knowledge demonstrated through syllogism.

Analyze how syllogisms connect major and minor premises to conclusions, deriving scientific truths from first principles. Explore how premises justify conclusions and distinguish knowledge from true belief in Aristotle’s account.

Explore medieval epistemology through features of medieval philosophy, its Christian influence, metaphysical interests, and doctrine of reality, reading epistemology as influenced by neo plagiarism and new Aristotelian philosophy.

Saint Augustine links soul and body in perception, suggests concepts resemble platonic forms, and holds that all knowledge requires divine illumination.

Augustine's Plato-influenced theology contrasts with Aquinas, who—shaped by Aristotle—advances knowledge from sensory to universal forms and divine truth via active and passive intellect, as early empiricism's founder.

Explore modern era rationalism and secular epistemology, contrasting medieval theology, the scientific revolution, and Descartes' method of doubt, plus primary and secondary qualities.

Descartes, a 17th-century French philosopher and mathematician, shifts philosophy from metaphysical reality to knowledge grounded in reason as the source of truth, father of modern Western philosophy and rationalism.

Descartes's aspiration to provide philosophy with a solid, self-evident foundation, free from skepticism and absolutely certain like mathematics, then deduces all claims via a deductive syllogism.

Explain four rules of the method of doubt: accept only clear and distinct ideas, divide problems, progress from simplicity to complexity, and complete every step for a solid, self-evident foundation.

Apply the Cartesian method of doubt to question sense perception and physical objects, then engage in hyperbolic doubt, doubting even mathematical truths, until reaching a self-evident foundation.

Descartes's method of doubting shows that thinking proves existence. Every act of doubt confirms 'I think, therefore I am' as the first philosophical foundation.

Explore the criterion of truth in epistemology through clear and distinct ideas, including Cogito ergo sum, which is self-evident and foundational because it is clear and distinct.

Examine the method of doubt to reveal its unique features, aims, and pursuit of something undoubted, distinguishing it from other skeptics' doubts.

Explore the three kinds of ideas in epistemology—adventitious ideas from external reality perceived by sense organs, fictitious ideas from imagination, and innate ideas that exist in the mind.

Explore Benedict de Spinoza as a rationalist who champions reason to overcome uncertainty and argues that knowledge frees us from the limits and imperfections of sense experience.

Explore Spinoza's geometric method in epistemology, using definitions, axioms, propositions, and proofs to derive knowledge from God as a self-evident substance.

Spinoza argues there is only one substance, God or nature, and that all things express or modify that single substance.

Spinoza posits one real substance with two attributes, thought and extension, not two substances, wherein God expresses infinite thoughts and bodies; every object and mind is a mode within nature.

Discover how Spinoza grounds truth in God as an axiom, deducing every idea from God's essence. Relate truth to intrinsic criteria and reflexive knowledge, manifesting certainty.

Explore Spinoza's coherence theory of truth, where a judgment is true to the degree it coheres with other judgments and the order of things.

Spinoza outlines three grades of knowledge: opinion from sense experience, which is inadequate; reason developed through common notions; and intuition, the knowledge of God's essential existence.

Explore Leibniz's view of a plurality of simple substances, or monads, each reflecting the entire universe from its own point of view and possessing internal properties and consciousness.

Explore monads as Leibniz's unique contribution to philosophy. Observe how each monad reflects the universe and evolves internally, with causality governed by pre-established harmony and God.

Explore how perception arises from mental life as an active property, with passive aspects shaping its development. Perceptions vary by moment and activity, with clarity tied to reflection.

Explore how the universe reflects through three levels of perception—from unconscious perception to self-conscious human reason—and consider God as the absolute unity grounding all reality.

Examine three principles guiding epistemology: the principle of contradiction, the principle of sufficient reason, and the identity of indiscernibles, and how they govern truth, reason, and identity.

The lecture explains two kinds of truth: truth of reason, necessary permanent truths, and truth of facts, contingent empirical truths, each grounded by a sufficient reason.

Explore Spinoza's three grades of knowledge—imagination from sense experience, reason, and intuition—and how adequate common notions reveal the universal properties and the necessary unity of God and nature.

Leibniz, a rationalist, argues innate ideas exist and challenge Locke's tabula rasa, claiming sense experience does not explain all ideas and emphasizing dispositions toward necessary truths, the marble metaphor.

Examine how rationalists foreground intellect as the source of knowledge and how reason offers certainty within epistemology, with the lecture moving to empiricism and related criticisms.

Explore empiricism as the opposite of rationalism, tracing Locke's sense experience as source of ideas, Berkeley's idealism, and the common rejection of innate ideas.

Examine John Locke's empiricism by refuting innate ideas and innatism, showing universal knowledge is impractical; he argues concepts like geometry and God arise from experience rather than birth.

Explore how tabula rasa challenges innate ideas, outlining two sources of knowledge—ideas of sensation and ideas of reflection—and how the mind forms complex ideas from simple perceptions, like an apple.

Examine modes, substances, and relations as a framework for organizing complex ideas, noting how ideas depend on substances for existence and relate through comparisons like father and child.

Explore Locke's distinction between primary qualities, which inseparably accompany objects and resemble the ideas they produce, and secondary qualities, which produce sensations but exist only in the mind.

The lecture outlines representative realism, showing the mind knows external objects only as representations, challenging one-to-one correspondence between ideas and reality, with primary qualities mirroring reality and secondary qualities varying.

Locke shows how we form abstract or general ideas by separating from time and place, creating universal concepts from experience, a form of conceptualism, and rejecting innate ideas.

Defines knowledge as the perception of the connection or disagreement among our ideas. Identifies four kinds of agreements and disagreements—identity, diversity, relation, and coexistence or necessary connection and real existence.

Locke outlines three knowledge degrees: intuitive, demonstrative, and sensitive; intuitive is most certain, demonstrative uses mediating ideas and logic, and sensitive concerns the existence of particular beings.

Berkeley defends common sense and religion against skepticism, rectifies Locke's limits on abstract ideas, and argues that nothing exists except ideas and minds, while objects exist only as perceived.

Engage with the theory of ideas, showing that external existence depends on mind perception, and identify three kinds: simple ideas of perception, ideas of reflection, and compound ideas.

Examine Berkeley's idealism, where sensations are ideas composing external objects, and God's perception sustains them, addressing solipsism and preserving common sense knowledge of the external world.

Explore Berkeley's idealism, where external world knowledge rests on ideas perceived by minds, not material substances; he denies a real distinction between primary and secondary qualities.

Bartlett refutes Knox's abstract ideas and introduces his theory of inverses; Berkeley argues words refer to things without abstract ideas and general ideas arise from particular ones.

Explore the epistemology of knowledge, contrasting empiricist and rationalist views. Examine Berkeley's sense-perception foundation, direct perception vs. imagination, and the implications for skepticism.

David Hume, a British philosopher, argues that expedients is the only source of knowledge, while acknowledging limits beyond our senses in understanding, and concludes that skepticism is an unavoidable consequence.

Explore Hume's distinction between impressions and ideas, and how simple impressions give rise to simple ideas, forming complex ideas through combination, with examples like color and taste.

Distinguish impressions from ideas by noting that impressions are potent perceptions, while ideas are faint images; sleep fever or madness may produce ideas near impression strength, though rarely.

Examine sensation and reflection impressions, how sensation arises in the soul from unknown causes and reflection from seeds of mental operations, triggering desire, aversion, hope, and fear.

Hume links ideas through three association rules—resemblance, contiguity, and collegiality—and argues that general ideas emerge from habit, not abstract forms.

Hugh distinguishes two kinds of propositions: ideas, with impossible negation, and matters of fact, knowable by experience, with possible negation. Examples include tautologies and causal claims like fire causes heat.

Hume argues that causal belief arises from habit, not logical necessity, via repeated constant conjunction, as in cloud implying rain but not guaranteeing future occurrences.

Expose Hume's skepticism of causation, showing past experience of contiguity forms beliefs by custom rather than reasoning. Conclude that there is no logical connection between cause and effect.

explore how epistemology debates define substance, contrasting empirical and rationalist positions; view external objects as collections of simple ideas shaped by imagination, coherence, consistency, and habit.

Examine Hume's view that the mind is a bundle of perceptions, not a fixed self, and that identity arises from coherence of impressions and ideas, fueling skepticism and empiricism.

Explore Emmanuel Conte's critical epistemology, bridging rationalism and empiricism, drawing boundaries between proper and improper use of reason in metaphysical claims, guided by the Critique of Pure Reason.

Explore Kant's bridge between rationalism and empiricism, showing that knowledge arises from both perceptions and concepts, with the mind constituting experience through necessary categories.

Explain a twofold judgments framework, a priori judgments known, and analytic versus synthetic judgments, where analytic predicates are in the subject, and denial leads to contradiction while synthetic adds information.

Explore Kant's propositions on human knowledge, distinguishing analytic a priori, synthetic a posteriori, and synthetic a priori judgments, with examples like red flowers, triangles, and every event has a course.

Explore synthetic a priori knowledge and how judgments yield new information beyond analytic meaning, independent of experience, shaped by the form of sensibility, and linked to causes and effects.

Conte presents the idea of synthetic a priori knowledge to explain transcendental idealism, showing that scientific knowledge combines sense experience with mind-contributed content.

Explore transcendental idealism by examining space and time as the forms of sensibility that structure experience, distinguishing sensible intuition from content, and showing how space and time shape knowledge.

Explore Kant's 12 categories of mind that actively structure experience, guiding judgments by classifying sense experience into causality, existence, possibility, reciprocity, and necessity, contrasting with Hume's habit-based view.

Explore transcendental idealism, showing we cannot know things in themselves; we know phenomena shaped by the mind's space-time intuition and a priori categories yielding objectively and universally valid knowledge.

Explore Kant's Copernican revolution in epistemology, showing that knowledge arises when representation makes the object possible, as the mind shapes experience.

Bridge rationalism and empiricism through Kant’s transcendental idealism, showing how reason and synthesis shape knowledge in epistemology.

Explore how space, time, and the mind's categories shape experience, bridging rationalism and empiricism through Kant’s transcendental idealism and synthetic a priori concepts.

Explore the phenomenal and noumenal worlds, and Kant's critique of rationalism and empiricism, showing mind dependent categories shape experience and limit access to things as they are.
