Question

(a) "We should look not to an ideal language which derives its meaning from facts and has a precise logical structure but empirically, to the ways in which languages are actually used." Explain the transition from early views of Wittgenstein to his later views on language and meaning with reference to this statement. 20

(b) Present an exposition of the verification theory of meaning as propounded by the logical positivists. In this context also differentiate between the "strong" and the "weak" sense of the word "verifiable". 15

(c) "Blue is one object of sensation and green is another, and consciousness, which both sensations have in common, is different from either." Present an account of Moore's refutation of idealism with reference to this statement. 15

The directive 'explain' demands clear exposition of philosophical transitions and theories with logical progression. Structure: Introduction (2-3 lines) noting the linguistic turn in 20th century philosophy; Body divided into three sections—(a) Wittgenstein's transition from Tractarian picture theory to language-games (~40%, 800 words), (b) Logical Positivism's verification theory with strong/weak distinction (~30%, 600 words), (c) Moore's refutation of idealism via diaphanous consciousness (~30%, 600 words); Conclusion (2-3 lines) synthesizing how these approaches collectively shifted philosophy from metaphysical abstraction to linguistic analysis.
- For (a): Early Wittgenstein's picture theory (Tractatus 1-2.1), isomorphism between proposition and fact, saying vs. showing distinction, and the ideal language assumption
- For (a): Later Wittgenstein's critique of private language, language-games (PI 23), family resemblances, meaning as use (PI 43), and rejection of essentialism
- For (b): Verification principle (A.J. Ayer, Carnap), elimination of metaphysics, strong verifiability (conclusive verification) vs. weak verifiability (probabilistic confirmation)
- For (b): Problems with verificationism (self-refutation, Hempel's critique, Quine's attack on reductionism) and shift to falsification or liberalization
- For (c): Moore's 'Refutation of Idealism' (1903), diaphanous nature of consciousness, act-object distinction, open question argument against naturalistic fallacy
- For (c): Moore's commonsense realism, external world proof (hands argument), and separation of consciousness from its objects
- Comparative element: How Moore's direct realism contrasts with Wittgenstein's linguistic turn, yet both oppose idealism
- Synthesis: The broader trajectory from psychologism/logical atomism to ordinary language philosophy and conceptual analysis

Dimension	Weight	Max marks	Excellent	Average	Poor
Concept correctness	20%	10	Precise articulation of Tractarian picture theory (isomorphism, logical form), accurate distinction between strong and weak verification with examples (protocol statements vs. scientific laws), correct interpretation of Moore's diaphanous thesis and act-object distinction; no conflation of early/late Wittgenstein or misattribution of verificationism to Wittgenstein	Broadly correct identification of theories but with minor errors—e.g., vague on 'language-games' specifics, conflating verification with falsification, or misstating Moore's argument as purely commonsense rather than conceptual analysis	Fundamental misconceptions—treating verificationism as Wittgenstein's view, confusing picture theory with language-games, or presenting Moore as merely asserting common sense without philosophical argument
Argument structure	20%	10	Clear logical progression within each sub-part: for (a) explicit contrast between Tractatus and Philosophical Investigations with textual markers; for (b) systematic exposition of verification principle followed by strong/weak distinction with illustrative examples; for (c) Moore's step-by-step argument from sensation to consciousness to external reality; effective transitions between parts showing thematic connections	Adequate structure with identifiable sections but uneven development—e.g., thorough on Wittgenstein but rushed on verification types, or descriptive rather than argumentative treatment of Moore; some logical gaps in connecting premises to conclusions	Disorganized or fragmented response—jumbling thinkers together, lacking clear section demarcation, presenting bullet points without argumentative flow, or failing to address the 'transition' aspect in (a) or the 'differentiate' directive in (b)
Schools / thinkers cited	20%	10	Specific citations: for (a) Tractatus Logico-Philosophicus (1921) and Philosophical Investigations (1953) with section numbers; for (b) Vienna Circle (Schlick, Carnap), A.J. Ayer's Language, Truth and Logic (1936), Hempel's later critique; for (c) G.E. Moore's 'Refutation of Idealism' (Mind, 1903) and 'Proof of an External World' (1939); contextual placement of logical positivism within broader analytic movement	Correct identification of main figures but imprecise references—e.g., 'Wittgenstein said' without textual specificity, 'logical positivists' without individual names, Moore mentioned without article titles; missing secondary figures like Waismann or Neurath	Significant omissions or errors—missing Vienna Circle entirely, attributing verificationism to Popper, confusing Moore with Russell on idealism, or anachronistic citations; reliance on generic 'analytic philosophers said'
Counter-position handling	20%	10	For (a): Acknowledges Kripke's skeptical interpretation or Malcolm's defense; for (b): Addresses self-refutation charge (is verificationism itself verifiable?), Hempel's critique of observational basis, Quine-Duhem thesis; for (c): Notes Berkeley's possible rejoinder, phenomenalist alternative, or Strawson's later critique of Moore's 'know' claims; demonstrates awareness that these positions were responses to specific philosophical problems	Brief mention of obvious objections—e.g., verificationism's self-refutation noted without elaboration, or Moore's argument called 'naive' without specifying why; superficial engagement with alternative interpretations	No counter-positions addressed, or misidentified—e.g., presenting idealism as merely 'subjective' without Berkeley's esse est percipi, ignoring that verificationism faced internal critiques from within Vienna Circle, or treating Moore's opponents as straw men
Conclusion & coherence	20%	10	Synthesizes three sub-parts into coherent narrative about analytic philosophy's development: from Moore's break with British idealism, through logical atomism and positivism's scientific aspirations, to Wittgenstein's therapeutic turn; notes enduring tensions between systematic and ordinary language approaches; evaluates which insights remain philosophically viable; returns to epigraph's theme of empirical vs. ideal language	Serviceable conclusion summarizing main points without deeper synthesis; treats three parts as separate exercises without thematic integration; generic statement about 'importance of language in philosophy'	Missing or abrupt conclusion; no connection between sub-parts; ends with repetition of introduction; or introduces entirely new claims in conclusion without support; failure to address the question's framing statement about empirical vs. ideal language
