90 mins of philosophy with Alex O'Connor: God, nihilism, and ethical emotivism

Key Concepts

First Cause Argument: A philosophical argument for the existence of God based on the idea that the universe must have an initial cause.
Hierarchical Causation: A type of causation where each element in a chain borrows its causal power from a more fundamental element, requiring a foundational cause.
Horizontal Causation: A type of causation in time where earlier causes do not need to persist for the chain to continue (e.g., dominoes falling).
Unactualized Actualizer: In Aquinas's argument, a being that is pure act, with no potentiality, and is the ultimate source of actualization.
Problem of Evil/Suffering: The argument against the existence of an all-powerful, all-knowing, and all-good God due to the existence of suffering in the world.
Nihilism: The belief that life is without objective meaning, purpose, or intrinsic value.
Ethical Emotivism: The metaethical theory that ethical statements are expressions of emotion or attitude, not factual claims that can be true or false.
Non-cognitivism: The view that ethical statements do not express propositions and therefore cannot be true or false.
Frege-Geach Problem (Embedding Problem): A challenge to emotivism, arguing that if ethical statements are mere expressions of emotion, they cannot function meaningfully within logical arguments or complex sentences.

Arguments for and Against the Existence of God

The First Cause Argument (Hierarchical Causation)

The video presents a nuanced version of the first cause argument, distinguishing between horizontal and hierarchical causation.

Horizontal Causation: This is the more intuitive understanding of cause and effect, often thought of in terms of time. For example, pouring water into a glass is an efficient cause. If this chain of causes extends infinitely backward in time (like dominoes falling), it doesn't necessarily require a first cause, as each prior cause has its own causal power to initiate the next event. The example of parents and children illustrates this: a grandfather causes a father to exist, and then the grandfather can die while the father still has the power to cause the speaker's existence.
Hierarchical Causation: This type of causation occurs simultaneously and is dependent on a sustaining cause. The example of a glass of water being held up illustrates this: the water is held by the glass, the glass by the hand, the hand by the arm, and so on. In this chain, each element only has causal power because it borrows it from the element below it. The glass cannot hold the water without the hand, the hand cannot hold the glass without the arm, etc.
- Key Point: This hierarchical chain cannot go on infinitely because if each element is merely borrowing causal power, then at some point, there must be a fundamental source of that power. If the chain went back infinitely, no element would have any actual causal power, as it would always be borrowing from something that has no power itself.
- Sustaining Cause: This fundamental cause is not a "first cause" in the temporal sense (something that set things in motion long ago) but a sustaining cause that keeps things in existence and functioning now. Gravity, for instance, sustains objects in position.
- Argument's Conclusion: This argument, when applied to the universe, suggests the existence of a foundational, sustaining principle that is necessary for the entire causal chain to exist and operate. This principle is "insensitive to time" and requires existence "right now."

Aquinas's Argument from Change (Motion)

Thomas Aquinas's argument from change, also known as the argument from motion, is discussed as another causal argument.

Potentiality and Actuality: Change is defined as the actualization of a potential. For example, a hot cup of coffee (potential to be cool) cools down.
Actualizer: Potentiality can only be actualized by something that is already actual. A potentially cold fridge cannot make a hot cup of coffee cold; an actually cold fridge is required.
Unactualized Actualizer: Following this logic, Aquinas argues that there must be a being that is pure act, with no potentiality, to actualize all other potentials. This being is the "unactualized actualizer."
Immateriality: Aquinas further argues that if this first cause has zero potentiality, it cannot be material, as material things have potential (e.g., they can be divided or moved). Therefore, the first cause must be immaterial.
Attributes of God: Through further reasoning, Aquinas attempts to establish that this first cause must also be timeless, spaceless, and creative, leading to a concept of God.

The Problem of Suffering (Argument Against God)

The problem of evil, reframed as the "problem of suffering," is presented as the strongest argument against the existence of a traditionally conceived God.

The Dilemma: If God is all-powerful, all-knowing, and all-good, why does immense suffering exist in the world?
Evolution by Natural Selection: The video highlights that life on Earth, including human life, is a product of evolution by natural selection. This process inherently involves "survival of the fittest," which translates to the destruction, death, and suffering of the weakest.
Scale of Suffering: For billions of years, life has existed in a state of brutal competition, with predation, disease, and mass extinctions. The suffering of animals, who do not have the promise of eternal life, is described as "unfathomable."
God's Choice of Mechanism: The argument questions why an all-good and all-powerful God would choose a mechanism for creation that is intrinsically built upon such widespread suffering.
Conclusion: While not a logical disproof, the problem of suffering presents a significant challenge to the belief in a benevolent God, making the existence of such a God seem "unexpected." It primarily argues against a good God.

Synthesis on God's Existence

The speaker, Alex O'Connor, believes there are strong arguments for a foundational principle or a necessarily existing being (a first cause). However, he views the Judeo-Christian tradition as an "imperfect approximation" of this being, acknowledging it gets much right but also much wrong. He favors individuals who are open to the possibility of a God or a foundational cause without rigidly adhering to specific doctrines. He also critiques deism, the idea of a God who set the universe in motion and then withdrew, arguing that the hierarchical causation argument implies a God who is continuously sustaining reality.

Understanding Nihilism and the Human Condition

Defining Nihilism

Nihilism, broadly defined, is the lack of belief in, or the belief that there is no such thing as, objective purpose to life or human actions.

Groundless Values: Nihilism analyzes values and finds them to be essentially groundless or based on subjective preferences.
Not Apathy: It's crucial to distinguish nihilism from apathy or a lack of motivation. While there can be a correlation between philosophical nihilism and depression, nihilism itself is about the purpose and meaning behind actions, not the absence of desire or motivation.
Camus's Sisyphus: The concept is illustrated by Albert Camus's description of Sisyphus, who recognizes the repetitive, seemingly meaningless structure of his daily life. The realization that there is "no meaning to any of this, that there's nothing more than just my doing it" is the core of the nihilistic insight.

Meaning vs. Purpose

Meaning as Purpose: Meaning is often used synonymously with purpose, defined as a reason to act or a reason to be.
Contingent Chains: Reasons for actions are typically contingent on other reasons (e.g., reaching for water because of thirst, thirst because of biology, biology due to evolutionary principles).
Objective Meaning: An objective meaning would require a non-contingent, self-justifying principle that doesn't depend on subjective preferences.
Subjective Self-Justifying Principles: Most people find their "meaning" in self-justifying principles, which are often subjective (e.g., caring for children, religious devotion to God). These principles are the point where the "why" question feels inappropriate.

Nihilism and Values

Analysis of Values: Nihilism doesn't eliminate values but analyzes them and finds them to be groundless or rooted in subjective preferences.
Experiencing Values: Even a nihilist still experiences values in a practical sense. They will still feel thirst and value quenching it, or experience pleasure and pain.
Meaningless Suffering/Happiness: Nihilism's impact is on the meaning attributed to these experiences. Suffering is amplified by the recognition that it is meaningless. Conversely, happiness, while still felt, is recognized as meaningless.
Correlation vs. Causation: While nihilism can lead to depression, the speaker suggests that people might be nihilists because they are depressed, rather than the other way around.

The Universality of Felt Meaning

Drive for Meaning: There appears to be a universal human compulsion to believe in objective meaning.
Evolutionary Explanation: This drive can be explained through evolutionary pressures that favor motivated individuals.
Treating Felt Meaning as Objective: The speaker suggests that the universality of felt meaning might be enough for practical purposes, akin to treating a universally preferred color (blue) as objectively the best for painting a house, even if it's technically subjective.

Historical Context of Nihilism

Not a New Phenomenon: Nihilism is not solely a modern response to the decline of religion. The speaker posits that religions may have emerged as responses to nihilism.
Book of Ecclesiastes: The book of Ecclesiastes in the Old Testament is presented as a significant exposition of nihilistic themes, with its repeated assertion of "hebel" (vanity, wind, absurd).
Existentialism and Absurdism: Later thinkers like Nietzsche, Sartre, and Camus are associated with nihilistic themes, with Camus's "The Myth of Sisyphus" famously concluding with the idea of imagining Sisyphus happy.
Narrative Form: Nihilistic literature often appears in narrative form (e.g., Ecclesiastes, novels like Turgenev's "Fathers and Sons"), suggesting it's a problem best understood through lived experience rather than abstract philosophical discourse.

Agnosticism and Personal Conviction

The speaker finds personal solace in agnosticism regarding existential questions.

Lack of Conviction: Not being convinced of nihilism (or any specific answer) prevents him from being deeply upset by the possibility of meaninglessness.
Plausibility vs. Certainty: He acknowledges the plausibility of nihilism due to the apparent arbitrariness and suffering in the world, but also finds it implausible that existence is entirely without reason.
Emotional Influence: The speaker emphasizes that emotional states heavily influence philosophical beliefs. People often adopt philosophies that align with their existing feelings (e.g., becoming nihilist due to depression).
Attraction to Philosophy: Philosophical positions are often adopted because they articulate something the reader already intuitively grasps or feels.

How Emotivism Shapes Ethics

Emotivism Defined

Emotivism is a metaethical theory that posits ethical statements are not factual claims but rather expressions of emotion or attitude.

Contrast with Subjectivism: While related to subjectivism (which sees ethics as opinion), emotivism goes further. Subjectivism might say "Murder is wrong" means "I don't like murder" (a claim about one's psychology). Emotivism says it's the expression of that dislike, like saying "Ugh, murder!" or "Boo, murder!"
Non-Cognitivism: Emotivism is a form of non-cognitivism, meaning ethical statements do not have truth value (they cannot be true or false). They are akin to commands or exclamations.
A.J. Ayer: The theory is largely attributed to A.J. Ayer, who argued in "Language, Truth & Logic" that statements are only meaningful if they are empirically verifiable or analytically true. Ethical statements, he concluded, were neither, and thus must be expressions of emotion.

Ethical Debate and Emotivism

Debate on Descriptive Facts: Emotivism suggests that much of what appears to be moral debate is actually debate about descriptive facts. For example, arguments about gun control involve statistics and factual claims, not just moral pronouncements.
Shared Emotional Responses: Once factual disagreements are resolved, the remaining "moral" element is the expression of emotion. The speaker suggests that fundamental ethical issues might involve shared emotional predispositions due to our shared humanity and evolutionary heritage.
Conflicting Emotions: The challenge arises when people have genuinely conflicting emotional responses. The emotivist might argue that these conflicts can be broken down further, or that they simply represent irreconcilable differences in fundamental emotional reactions.
Mistakes in Emotional Expression: The speaker proposes that while emotions themselves aren't true or false, one can make "mistakes" in their emotional expressions if they are based on false beliefs (e.g., being upset about rain that isn't actually happening). This allows for a form of rational persuasion by correcting factual misunderstandings.

The Nature of "Wrongness"

Unique Emotion: Emotivism doesn't equate "wrongness" with existing emotions like anger or disgust, but rather posits it as its own unique emotion or attitude.
Incest Taboo Example: The near-universal incest taboo is used as an example. While evolutionary explanations exist, they don't justify the moral prohibition. Emotivism suggests the strong prohibition stems from a deep-seated emotional reaction of disgust or revulsion, which is the "wrongness" itself.
Homophobia Example: Similarly, strong homophobic sentiments are characterized not as dispassionate moral judgments but as visceral emotional reactions.

The Meaning of Ethical Language

Translating Ethical Statements: Emotivism translates ethical statements into expressions of preference or attitude. "The world ought to be this way" becomes an expression of dissatisfaction with the current state of the world.
Beyond Reporting Psychology: The key distinction is between reporting a psychological state ("I don't like murder") and expressing that state ("Boo, murder!"). Ethical statements are seen as the latter.
"Good" and "Bad": The speaker reflects on the difficulty of defining "good" and "bad" and concludes that the difference between a factual statement (e.g., "It's raining") and a moral one (e.g., "It's bad that it's raining") lies in the added attitude or feeling.

The Frege-Geach Problem

Embedding Problem: This is a significant challenge to emotivism. It argues that if ethical statements are mere emotional expressions, they cannot function coherently within logical structures like conditional statements ("If murder is wrong, then murdering James is wrong") or interrogatives ("I wonder if murder is wrong").
Meaning Retention: In complex sentences, the meaning of constituent parts usually remains consistent. However, if "murder is wrong" means "Boo, murder," then "I wonder if Boo, murder" or "If Boo, murder, then..." makes little sense.
Truth Value in Context: The problem suggests that in these embedded contexts, ethical terms seem to acquire a truth value, implying they are not merely emotional expressions outside of these contexts either.
Logical Validity: The validity of arguments like syllogisms relies on the truth-aptness of their premises. If "murder is wrong" cannot be true or false, then arguments containing it cannot be logically valid in the traditional sense, which seems counterintuitive.
