Highlights:

• The Question Behind All Questions: What Is Knowledge? Dallas begins the course by identifying the central aim: to understand the ontology of knowledge—its structure, parts, and how it fits into reality. Rather than asking what we can know, he focuses on what it means to know, setting the stage for a critical evaluation of centuries of epistemology.
• Two Failed Strategies: Ideas and Language: Modern attempts to explain knowledge, Dallas argues, have leaned either on ideas (from Descartes onward) or on language (from the linguistic turn). Both approaches suffer from the same fatal flaw: they fail to account for intentionality and how consciousness connects to the real world without distortion.
• Knowledge as Act and Disposition: Dallas introduces a crucial distinction: knowledge is both an act (e.g., discovering you have a flat tire) and a disposition (e.g., knowing the alphabet). Understanding knowledge requires grasping both aspects—and recognizing how each is structured and grounded in reality.
• Who Decides What Counts as Knowledge? He explores how the institutionalization of knowledge in secular systems has deliberately excluded theistic claims. What is accepted as knowledge shapes cultural authority and action—making the status of Christian claims as knowledge, not mere belief, a deeply important issue.
• The Problem of Objectivity and the ‘Blur’: Modern theories often conclude that we cannot know things as they are in themselves—Dallas calls this a philosophical dead end caused by a failure to account for the full determinacy of conscious acts. These theories leave us with “blurs”—incoherent accounts that cannot explain how knowledge genuinely relates to reality.
• Toward a Realist Ontology of Knowledge: Dallas proposes a path forward: knowledge must be understood as a fully determinate event, not reducible to subjective states or linguistic conventions. By clarifying the act of knowing in ontological terms, we recover the possibility of objective knowledge—including knowledge of God, the soul, and morality.

Highlights:

• The Problem of the Criterion Revisited: Dallas critiques Chisholm's trilemma—skepticism, methodism, or particularism—noting that it traps us in question-begging unless we acknowledge real cases of knowledge. He argues instead that we can begin with clear examples of knowing and work toward identifying their essential structure, thus avoiding philosophical dead-ends.
• Knowledge as a Structured Whole: Dallas emphasizes that an act of knowing is not a mere psychological occurrence but a structured event. Like a physical object with parts and properties, an act of knowledge has components (like representation and judgment) that must be examined ontologically to avoid the "blur" that plagues traditional epistemology.
• Sellars and the Illusion of Verification: In reviewing Sellars' theory of sentence verification, Dallas shows that the attempt to reduce knowing to a co-occurrence of sentence and sensation fails. He critiques Sellars’ reliance on “rules” as a substitute for essence, revealing that the account lacks the necessary ontological depth to explain how language genuinely connects with reality.
• Fulfillment and Presence in Husserl: Dallas introduces Husserl’s notion of fulfillment, where knowledge arises when an object becomes present to consciousness as it was intended. He highlights the difference between empty intentions (conceptual projections) and their fulfillment in perception, offering a more robust and dynamic understanding of how we come to know.
• Concepts as Intentional Properties: Exploring the nature of concepts, Dallas presents them as properties of mental acts that naturally correlate with the properties of the objects they are about. This intentional nexus is foundational to meaningful knowing, and it avoids the pitfalls of both nominalism and extreme linguistic approaches.
• The Necessity of Ontology for Epistemology: Dallas asserts that any coherent theory of knowledge must begin with ontology—the study of what is. Trying to derive a theory of knowledge from language or sensations alone is doomed to incoherence, and only a structurally aware ontology of acts can ground a meaningful realism.

Highlights:

• The Authority Crisis in Knowledge Determination: Dallas begins by raising the critical issue: who decides what counts as knowledge today? He critiques how Christian colleges drift from a knowledge tradition rooted in Scripture to academic standards defined by secular institutions, resulting in a loss of authority and coherence.
• Knowledge as an Intentional Structure: Dallas explores how modern views wrongly locate authority in the reader rather than in the scriptural text itself. He connects this to broader philosophical issues, noting that once the authority of the text is lost, knowledge becomes personalized and relativistic, echoing the critiques of Thomas Nagel and others.
• Who Gets to Decide What Counts as Knowledge?: A pivotal moment comes when Dallas critiques how institutions (journals, grant agencies, professional orgs) set the terms of knowledge. He warns that empiricists who never examine the flaws of naturalism end up moving in blind conformity, reinforcing groupthink rather than truth.
• Fulfillment and the Object of Knowledge: Dallas guides students through Husserl’s concept of intentionality—how mental acts are about objects—and fulfillment, where these acts culminate in contact with the object itself. He uses the example of walking toward a tree to illustrate how our understanding “fills out” empty intentions until the object is genuinely encountered.
• The Compatibility of Transcendence and Immanence: Drawing on Husserl and Brentano, Dallas explains how an object can be transcendent (existing independently of the mind) and yet immanent (present within experience through fulfillment). This balances realism with phenomenology, refuting the idea that objects must be inside the mind to be known.
• Against Subjectivism—Knowledge Is About Reality: Dallas critiques views that lock knowledge within the mind, like those of Locke, Kant, and modern constructionism. He advocates for treating cognitive acts as natural wholes that relate to external objects without transforming them—preserving the possibility of knowing things as they are.

Highlights:

• Prayerful Orientation: Dallas opens the session by grounding the inquiry in prayer, asking for clarity and help in discerning what matters most. He sees the intellectual work ahead as service to God's purposes, emphasizing the spiritual dimension of philosophical reflection.
• The Difference Between Representation and Intuition: He distinguishes between acts of representation—symbolic or indirect—and acts of intuition, where the object is fully present to the mind. Intuition is not something a representation turns into; rather, it is a different kind of act altogether.
• Degrees of Fulfillment in Knowing: Dallas explains that knowledge depends on the fulfillment of intentions, where what one thinks is matched by what is actually present. This fulfillment can range in clarity and completeness, and is essential to identifying when true knowing occurs.
• Consciousness as Complex and Layered: He describes consciousness as inherently multifaceted—never just focused on a single object, but always carrying layers of awareness, memory, and judgment. Acts like counting or experiencing a symphony illustrate how multiple mental elements interweave.
• Critique of Transformative Theories of Consciousness: Dallas critiques the idea that the mind transforms objects just by perceiving them, what he calls “Midas Touch epistemology.” Instead, he affirms that the object remains what it is; knowledge comes through relation, not alteration.
• Attention as the Foundation of Self-Knowledge: He argues that we know mental events not by introspection in the traditional sense, but by attending to them directly. Attending is a basic mental act, just like turning a key, and it is the means by which we access our thoughts, sensations, and intentions.

Highlights: 

• Critique of Eliminative Materialism: Dallas unpacks William Lyons' attempt to eliminate introspection by comparing it to discarding belief in witchcraft. He points out the desperate contortions in Lyons' language as a sign of conceptual failure, and insists that our awareness of mental acts—such as noticing a fuzzy letter at the eye doctor—cannot be reduced to dispositions or sociocultural constructs.
• Roast Pig Philosophy and Philosophical Storytelling: In one of his most vivid illustrations, Dallas warns against “roast pig philosophy”—the tendency to explain away real phenomena with speculative stories, like claiming pigs were first cooked accidentally by house fires. He applies this critique to theories that reduce introspection to brain activity without offering credible alternatives.
• The Need for Phenomenological Reflection: Dallas emphasizes phenomenology as a safeguard against misleading reductions. He argues that to understand our mental acts, we must reflect on them directly, without prematurely assuming they are reducible to brain states or external behaviors.
• Introducing the Ontology of Knowledge Framework: Dallas articulates the heart of his project: that knowledge must be treated ontologically—as structured wholes with parts, properties, and relations. Without this, epistemology easily devolves into skepticism or incoherence.
• Engaging Susan Haack's 'Foundherentism': He begins his critique of Haack by outlining her attempt to bridge foundationalism and coherentism through the metaphor of a crossword puzzle. While appreciating the effort, Dallas warns that her failure to offer an ontology of belief and justification will leave her theory vulnerable to significant blurring. 
• Blurring Between Belief Content and Belief State: Dallas pinpoints a key weakness in Haack's approach: the lack of clarity in distinguishing belief as a state (S-belief) and belief as content (C-belief). He argues that without a coherent ontology to link experiential causes to propositional content, her theory struggles to ground justification in anything truly truth-indicative.

Highlights:

• The Ambiguity of “Belief”: Dallas critiques Haack’s claim that the term belief is ambiguous. He argues instead that while belief has multiple applications (e.g., content vs. state), this does not make it ambiguous in a technical sense—drawing analogies to terms like Jack that have varied but coherent uses.
• Causation vs. Consciousness: He unpacks the subtle but crucial difference between perception causing a belief and perception being related to belief through consciousness. Dallas warns that replacing consciousness with causation may yield a more mechanistic but philosophically inadequate account of how we come to know things.
• Foundationalism and “Last Best Hope”: Haack’s strategy to undermine foundationalism hinges on showing that even judgments about immediate experience (like how lines appear) are fallible. Dallas argues this overstates the case and that some awarenesses—such as of fulfillment or certain internal states—may still be immune to doubt.
• Describing the Causal Web: Dallas walks through Haack’s detailed breakdown of what constitutes a belief’s causal background—its “S-evidence.” This includes perceptual states, introspective states, memories, and other beliefs. However, he remains skeptical that listing these causes suffices to establish justification.
• The S-to-C Evidence Bridge: A central issue in Haack’s theory is how to move from S-evidence (states) to C-evidence (propositions). Dallas notes this bridge is intentionally constructed through propositions that describe belief-causing states—but warns that the ontological and semantic status of this transition remains murky.
• Degrees of Justification and Explanatory Integration: In evaluating Haack’s three factors—how favorable, how secure, and how comprehensive one’s C-evidence is—Dallas focuses on “explanatory integration.” He clarifies that Haack is essentially replacing deductive logic with a looser model of coherence, like solving a crossword puzzle, which may offer some utility but lacks rigor and determinacy.

Highlights:

• Supportiveness and Explanatory Integration: Dallas unpacks Haack’s idea that “supportiveness” means how well a belief integrates explanatorily with other beliefs and experiences. He notes that explanatory integration is not strictly a logical relation and critiques the vagueness of this foundational concept.
• Independent Security and the Crossword Puzzle Analogy: Dallas explains Haack’s analogy of a crossword puzzle to illustrate “independent security”: different beliefs supporting the same conclusion independently. While helpful, he points out that this analogy only partially clarifies the concept and doesn't solve deeper questions about evidential support.
• Comprehensiveness as a Justification Factor: Haack’s third criterion, comprehensiveness, is introduced as a safeguard against omitting relevant evidence. Dallas notes its intuitive appeal but emphasizes that there is always uncertainty about what is relevant—raising concerns about the reliability of this criterion.
• Degrees of Justification and the Truth Gap: Dallas highlights that Haack allows for varying degrees of justification without guaranteeing truth. He warns that her model lacks clear thresholds, making it hard to say when justification actually results in knowledge or reliable belief.
• Ratification and Truth-Indicativeness: Dallas walks through Haack’s attempt to argue that her criteria are truth-indicative, relying on evolutionary reasoning and a "hope" that inquiry leads to truth. He critiques the leap from explanatory coherence to truth-likeness as unsupported and possibly circular.
• The Realist Tension and the Failure of Confrontation: Dallas emphasizes Haack’s inability to show how beliefs confront or correspond to the world, given her denial of direct access to reality (“we cannot get outside our skins”). He argues that this undercuts any realist aspirations and makes her truth-indicativeness claim fragile at best.

Highlights:

• The Problem of Missing Pieces: Dallas opens by pointing out that Haack never fully constructs a theory of justification—she critiques others but leaves essential elements vague. Her lack of a clear account of experiential anchoring and explanatory integration reveals a gap at the heart of her framework.
• Justification Without Contact: Haack claims that beliefs justified on her terms are “truth indicative,” but Dallas highlights her own admission that she cannot provide a precise explanation of this. Because the object of belief is never directly encountered, her model leaves us unable to check our beliefs against the world itself.
• The Failure of Causation Alone: Attempting to base perceptual knowledge on causation, Haack assumes that sensory states can justify beliefs without clarifying how they are about real-world objects. Dallas critiques this as an ontological blur—causation cannot account for intentionality or the direct grasp of objects.
• No Way to Compare Belief with Reality: Dallas argues that Haack’s theory traps us inside our “S-evidence” and “C-evidence,” rendering it impossible to compare beliefs with the facts they’re about. Without a theory of intentionality, beliefs float within a self-contained web, disconnected from external reality.
• The Spiritual Nature of Consciousness: Dallas stresses that consciousness—intentionality, awareness, meaning—cannot be accounted for within a purely physicalist framework. He insists that an adequate epistemology demands a spiritual or non-naturalist account of the mind, one that can bridge the gap between thought and world.
• Explanatory Integration and the Dog in the Room: Using the example of seeing a dog, Dallas shows how Haack’s model attempts to explain justification via coherence among propositions. But without an account of how sensory states represent what they’re about, even strong integration fails to secure contact with reality.

Highlights:

• The Central Problem of Justification: Dallas critiques Haack’s concept of explanatory integration as the crux of her justification theory, noting that while she tries to move beyond simple causation, she fails to explain how logical relations can enter into the life of the believer to make a belief rational. He points out that inference, unlike implication, is an actual event in consciousness and needs to be accounted for within the ontology of belief.
• Fulfillment and the Act of Belief: Dallas explains how belief often arises from a direct comparison between thought and reality. Using examples like finding car keys or seeing a dog in the room, he shows how “fulfillment”—when experience confirms thought—plays a vital motivational role in belief, an aspect Haack’s framework cannot adequately support due to her causal limitations.
• Constraint Without Causation: Belief, Dallas argues, is not merely caused but often motivated by rational reflection—a concept he borrows from Husserl. This “constraint without necessitation” is what distinguishes rational beings from machines, and is foundational for understanding belief as a will-based act rather than a passive state.
• The Ontological Blur in Haack’s Framework: Haack’s division between S-states (subjective, causal) and C-states (conceptual, logical) leads to a fundamental “blur,” according to Dallas. She never successfully shows how logical relations (C-evidence) connect back to the actual belief state (S-belief) to justify it, which undermines the credibility of her account.
• Foundationalism and the Loss of Experience: Dallas laments how modern philosophy has abandoned the common-sense hooks of truth and perception in favor of abstract notions like reference and rationality. He argues that this shift—fueled by naturalism—has gutted the ontology of experience and made knowledge itself appear unattainable.
• Changing the Climate of Belief: In a moving reflection near the end, Dallas responds to a student’s skepticism about cultural change. He encourages them not to underestimate the power of human effort—partnered with God’s work—to reshape prevailing beliefs. He shares historical moments when the intellectual climate changed dramatically, emphasizing that a return to a truth-based, God-aware intellectual life is not only possible but necessary.

Highlights:

• “Science Tells Us” Is a Misleading Phrase: Dallas strongly critiques the habit of claiming “science tells us” something as if science were a conscious agent. He emphasizes that only people tell us things, and attributing voice or authority to "science" without critical thought invites confusion and detachment from reality.
• The Fall of Perception in 20th Century Philosophy: Dallas sketches the philosophical shift from grounding reference in perception to grounding it in linguistic usage. He notes that perception once tied us to reality, but in modern thought, especially under the influence of Wittgenstein and Putnam, reference is governed more by language use than by actual perception.
• The Rise of “Pure Flow” and the Loss of Rational Anchoring: He outlines the intellectual progression from classical perception-based knowledge to the postmodern condition of “pure flow,” where concepts like truth and reason are reduced to power plays. In this view, nothing is about anything; there is only movement shaped by influence and control.
• The Missing Ingredient in Introspection: Aboutness: Dallas calls out Putnam’s introspective list—words, images, sensations, and feelings—for omitting the crucial element of intentionality or aboutness. He insists that we never have thoughts that are not about something, and that ignoring this leads to a deeply flawed understanding of consciousness.
• The Absurdity of Treating “Words” as Mere Physical Marks: Putnam’s theory depends on treating words as physical tokens or “thought signs.” Dallas critiques this view, warning that it confuses the physical form of a word with the meaning it carries, reducing language to inert symbols and missing the essential intentional connection to thought and reality.
• Why You Can’t Be a Brain in a Vat (According to Putnam): Dallas explains Putnam’s famous argument: if you were truly a brain in a vat, you couldn’t think or say that you were one, because you’d lack any causal contact with the real-world referents of “brain” or “vat.” But Dallas points out that this hinges on a theory of reference that denies the intrinsic intentionality of thought—a theory he finds ontologically impoverished.

Highlights:

• Language as a Shaper of World and Thought: Dallas explores how Putnam argues that language does not merely describe reality but helps constitute it. Yet, Dallas warns that treating objects as dependent on conceptual schemes introduces ontological blur, failing to explain how language actually refers to real things.
• The Twin Earth Thought Experiment: Dallas unpacks Putnam’s Twin Earth scenario, which attempts to show that meanings are not just “in the head.” Two identical people in two worlds use the same word (“water”) but refer to different substances. This supposedly shows that reference depends on external causal history, not internal mental content.
• The Rejection of “Magical” Theories of Reference: Putnam claims that reference isn’t intrinsic—that there are no “noetic rays” or natural connections between words and their objects. Dallas challenges this by asserting that reference often emerges through a direct grasp of the object, not simply through a social chain.
• The Central Role of Concepts in Intentionality: According to Dallas, concepts are not passive mental representations but active dispositions that enable us to grasp things. He contrasts this with Putnam’s view that concepts are signs used in particular ways, noting the latter fails to capture the essential “aboutness” of consciousness.
• Public vs. Private Signs and the Problem of Reference: Dallas scrutinizes Putnam’s claim that even private mental signs can carry meaning, highlighting a critical inconsistency. He argues that if reference requires public, socially sustained use, then private use cannot carry the same weight—an issue that Putnam’s theory glosses over.
• Introspective Awareness and the Reality of Aboutness: Dallas insists that human introspection reveals an immediate awareness of aboutness—what our thoughts are of—which Putnam’s theory dismisses. This leads Dallas to argue that Putnam’s denial of direct reference undermines our lived experience of thinking and knowing.

Highlights:

• Reference Requires Prior Awareness: Dallas critiques Putnam’s idea that we can assign reference to a word by simply intending it to refer to something. He points out that this is circular—because in order to refer, we must have already picked the object out, which means reference cannot originate this way.
• The Puzzle of Notional Reference: Putnam introduces the idea of “notional reference” to describe how we can think of things like cats or cherries without requiring their existence. Dallas argues that this move contradicts Putnam’s own framework and smuggles back in the very kind of mental intentionality his theory excludes.
• The Missing Role of the Person: Dallas observes a major gap in Putnam’s account: people. He notes that reference cannot occur without persons who intend, speak, and use words. By trying to avoid an individualistic view, Putnam loses sight of the fact that only persons—not words themselves—refer.
• Internal Realism and the Vanishing World: According to Putnam, objects don’t exist independently of conceptual schemes. Dallas unpacks the disturbing implication of this view: if reality is always constructed by language, then we are trapped inside our own frameworks, with no access to a world outside them.
• The Blurring of Type and Token: Dallas highlights another ontological blur in Putnam’s system: the unclear relationship between abstract word types and concrete word tokens. If reference depends on the type word, how do we bridge that to actual spoken or written words—and how do persons engage with these?
• Rationality as Internal Justification: Dallas walks through Putnam’s view that rationality must be grounded not in correspondence with an external world, but in what a community would accept under ideal conditions. This leads to the conclusion that truth is ultimately equated with ideal rational justification—not with contact with reality itself.

Highlights: 

• Rationality as the Core of Justification: Dallas explains that Putnam places rationality at the center of his theory of justification, because without it, there's no way to establish reference or truth. Since we cannot get outside the stream of language, rational acceptability becomes the anchor for meaning.
• The Nazi as the Test Case for Rationality: Putnam’s argument against moral relativism is built on the example of the Nazi, whose beliefs and goals are considered irrational because they require absurd factual claims or reject basic moral descriptions. Dallas walks through how this test case serves to anchor Putnam’s belief in rational moral judgment.
• The Collapse of Fact-Value Distinctions: Dallas highlights how Putnam insists that values and facts are inseparably intertwined. Concepts like "rational justification" and "truth" themselves depend on prior commitments to the good—there’s no neutral foundation beneath our systems of thought.
• The “Midas Touch” Theory of Consciousness: Dallas critiques the idea that consciousness and language always transform what they touch—making objects depend on our mental or linguistic framing. He connects this to the loss of realism in modern epistemology and the danger of falling into subjectivism.
• Postmodernism and the Death of the Individual Knower: Turning to Lyotard, Dallas explains how knowledge becomes commodified and defined by social systems and computer networks, rather than individual insight or understanding. The self becomes a “node” in a communication network, and knowledge is reduced to information flow.
• Language as the Social Bond and Arena of Struggle: Dallas unpacks Lyotard’s claim that language forms the very fabric of society—not as a medium of understanding, but as a space of conflict and power. This view displaces classical notions of truth and personal responsibility, replacing them with performative discourse governed by power and persuasion.

Highlights:

• Knowledge as Practice and Narrative: Dallas explains Lyotard’s shift from theoretical explanation to narration as the dominant mode of knowledge. He unpacks how this move redefines knowledge as a set of cultural performances and practices, dissolving any stable reference to truth or reality.
• The Decline of Grand Narratives: Dallas highlights Lyotard’s view that modern society has lost faith in overarching explanations—such as the liberation of humanity or the development of the nation—as legitimation structures. In their place, we now rely on local, temporary narratives that resist universal claims and make enduring institutions nearly impossible.
• Legitimation Through Performance: According to Lyotard, Dallas notes, knowledge is now justified by its usefulness or productivity—not by its truth. Whether in universities, governments, or corporations, the primary question has become not "Is it true?" but "What can it do?"
• The Rise of Petrology: Dallas introduces Lyotard’s final concept of petrology—a metaphor for the simultaneous running of many "language games" without any overarching authority. This diversity is celebrated as liberation from power and coercion, but Dallas questions whether such fragmentation can sustain justice or meaningful human life.
• The Loss of the Individual: Dallas critiques Lyotard’s tacit ontology by pointing out its erasure of the human subject. If knowledge is simply a function of discourse or performance, then the individual knower disappears—and so does the possibility of personal responsibility, moral obligation, or even justice.
• Two Decisive Counterarguments: To conclude, Dallas offers two philosophical arguments against the view that things take their properties from language or consciousness. The first, his “Saturday Night Special,” argues that language cannot possibly create the world we experience. The second, his “Master Argument,” shows that if everything depends on language, then language itself must also depend on a higher meta-language—leading to an infinite regress or contradiction.
