    Study Notes

    Logical Positivism

    • Logical positivism states that all meaningful knowledge claims must be either analytic (based on reason) or empirical (based on sense perception)
    • Logical positivism continues to influence how sciences are classified despite its decline in modern philosophy

    Empirical and Analytic Claims

    • Empirical claims are verifiable through sensory experience, often involving descriptions of the world
    • Examples of empirical claims include "The sun will rise tomorrow" or "The weather is warm"
    • Analytic claims are statements that are true by definition and involve logical or formal knowledge
    • Examples of analytic claims include “All bachelors are unmarried males” or “Triangles have three sides”
    • The truth of analytic statements is contained within the definitions of the terms used
    • Key Distinction: empirical statements are tested through observation (correspondence theory), while analytic statements are tested for logical coherence (coherence theory)

    Relation between Source of Knowledge and Knowledge Claims

    • Reason produces formal/analytic knowledge, where the truth of a statement is determined by logical relationships within a system (e.g., mathematics, logic)
    • Sense perception produces empirical knowledge, where the truth is dependent on observing the external world (e.g., scientific observations )
    • The truth of empirical statements is established by verifying their correspondence to facts in the real world
    • Coherence theory applies to formal knowledge, while correspondence theory applies to empirical knowledge

    Status of Evaluative Claims

    • Evaluative claims express judgments of value, morality, or aesthetics (e.g., “Stealing is wrong,” “The sunset is beautiful”)
    • These claims arise from passions and emotions, not reason or sense perception, according to Hume
    • Logical positivists may dismiss evaluative claims as meaningless because they are neither empirical nor analytic
    • Hume argues that these judgments are grounded in human emotional experience and are therefore valid forms of knowledge
    • Evaluative claims can be prescriptive (giving commands) or proscriptive (prohibitions)
    • They depend on public approval or consensus for justification rather than logical verification

    Application of Correspondence and Coherence Theories of Truth

    • Correspondence theory is used to verify empirical claims by checking if they correspond to observable facts in the external world
    • Coherence theory is applied to analytic claims, where truth is determined by logical consistency within a system
    • For evaluative claims, neither correspondence nor coherence theories directly apply
    • The inter-subjective agreement or public consensus of a concerned group often determines their validity

    Significance of Logical Positivism

    • Logical positivism's epistemological framework influences the division of knowledge into formal (reason-based) and empirical (sense-based) types

    Correspondence Theory of Truth

    • Truth depends on the correspondence between knowledge claims and reality
    • For a statement to be true, it must correspond to actual facts or states of affairs in the real world
    • This theory is more controversial because it involves verifying claims by comparing them to external realities, unlike the internal focus of coherence theory

    Key Differences: Coherence and Correspondence

    • Coherence Theory focuses on internal consistency within a system of knowledge, while Correspondence Theory relies on external verification with reality
    • Coherence Theory is often applied to abstract systems (e.g., logic, mathematics), while Correspondence Theory is typically used to verify empirical claims about the world

    Different Versions of Correspondence Theory

    • Realist Version: This version focuses on direct observation and evidence from reality
    • The realist version applies to both empirical and evaluative claims

    Application of Verification by Inter-Subjective Consensus

    • Inter-subjective consensus is used as a method of verifying evaluative claims under the Correspondence Theory

    Combination of Both: Deontology and Teleology

    • The strongest form of justification is when an act or policy is good both in itself (deontologically) and produces beneficial outcomes (teleologically)

    Your Obligation as a Critical Thinker

    • The fundamental obligation as a critical thinker is to never accept any statement or belief without adequate evidence
    • This is rooted in healthy skepticism, which requires either rejecting beliefs without evidence or suspending judgment until sufficient evidence is provided
    • Adhering to this principle fosters critical and independent thinking, reducing the acceptance of rumors, gossip, or unprovable claims

    Distinguish the Realm of the Known, Knowable, and Unknowable

    • The known includes established facts and knowledge supported by evidence (e.g., the existence of DNA, black holes)
    • The knowable involves claims that are currently being explored or could become known in the future, like cloning humans or understanding the origins of life
    • The unknowable comprises claims that cannot, in principle, be supported by evidence, such as beliefs in heaven, hell, or reincarnation

    Distinguish the Realm of the Provable and Unprovable

    • Provable claims fall within the realms of the known and the knowable, where evidence can either be produced or hypothetically produced
    • Unprovable claims reside in the realm of the unknowable, where no evidence can support the claims, making them unverifiable
    • Critical thinkers are advised to reject these claims unless they are considered evaluative
    • The overarching goal for a critical thinker is to classify claims appropriately: accept only those in the realm of the known, suspend judgment on those in the realm of the knowable, and reject those in the realm of the unknowable.
