The Existence of God
Design Argument (PBF9: 57-59)
William Paley's watchmaker analogy: If a watch found on the ground suggests a designer, so too does the complexity of the universe suggest an intelligent creator.
Argument from complexity and order in nature: The intricate mechanisms found in nature imply intentional design.
Criticism: Evolutionary theory offers a natural explanation for complexity without invoking design. The argument assumes purpose where natural processes suffice.
Cosmological Argument (PBF9: 54-56)
St. Thomas Aquinas' "Second Way": Everything in motion must be set in motion by something else, leading to an unmoved mover (God).
Causation and the necessity of a first cause: If everything has a cause, there must be an initial uncaused cause.
Criticism: The argument does not explain why the chain of causes cannot be infinite. It assumes the necessity of a first cause without proving it.
Ontological Argument (PBF9: 52-54)
St. Anselm’s definition of God: God is "that than which nothing greater can be conceived."
Argument: If God exists in the mind, He must exist in reality because existing in reality is greater than existing only in the mind.
Criticism: Existence is not a predicate (Kant’s objection). Just because we define something as existing does not make it so.
Pragmatic Argument (PBF9: 62-73)
Pascal’s Wager: It is rational to believe in God because the potential benefits (eternal life) outweigh the risks (finite loss if God does not exist).
William James’ "Will to Believe": Faith can be justified pragmatically if it leads to beneficial outcomes.
Criticism: The argument assumes belief is a choice and does not address which God or religion one should follow.
Problem of Evil (PBF9: 106-109, 139-151)
Logical problem: The existence of an omnipotent, omnibenevolent God seems incompatible with the presence of evil.
Responses:
Free will defense: Evil results from human freedom.
Soul-making theodicy: Suffering builds moral character.
Criticism: Does not account for natural evil (e.g., earthquakes). Some suffering appears gratuitous and unjustifiable.
Knowledge and Truth
Plato’s Cave (PBF9: 157-161)
Allegory representing ignorance vs. enlightenment.
Prisoners in the cave see only shadows, mistaking them for reality.
Philosophers are those who escape and see true reality.
Application: Questions about perception, education, and truth.
Nozick’s Experience Machine (PBF9: 162-163)
Thought experiment: Would you plug into a machine that provides perfect simulated pleasure?
Criticism of hedonism: Suggests pleasure alone is not enough for a meaningful life.
Application: Value of real experiences over mere pleasure.
Cartesian Skepticism (PBF9: 164-169)
Descartes' "Cogito, ergo sum" (I think, therefore I am).
Dream argument: Can we distinguish between dreaming and waking reality?
Evil demon hypothesis: What if an evil demon deceives us about everything?
Responses: Foundationalism, reliance on clear and distinct perceptions.
On Bullshit (Frankfurt, Canvas)
Distinction between lying and "bullshitting."
Bullshitters are indifferent to truth, focusing instead on persuasion.
Relevance to modern society: Misinformation, political rhetoric, and media bias.
The Mind
Could Machines Think?
Yes (PBF9: 282-295)
Turing Test: If a machine’s responses are indistinguishable from a human’s, it can be said to think.
Functionalism: The mind is what the brain does, similar to software running on hardware.
Criticism: Consciousness and understanding may not arise from mere computation.
No (PBF9: 295-308)
Searle’s Chinese Room Argument: A person following rules to manipulate symbols does not understand Chinese; similarly, a computer might simulate thinking without actual understanding.
Criticism: Might misunderstand how intelligence emerges from simple rules.
Personal Identity
A Dialogue on Personal Identity and Immortality (PBF9: 309-330)
Weirob vs. Miller: Debate on whether personal identity is tied to a soul, consciousness, or bodily continuity.
Memory theory: Identity persists through continuous memory links.
Problems:
Circularity: Memory presupposes identity rather than explaining it.
Fission cases: If a person’s consciousness is copied, which is the real self?
Meaning and Death
Sisyphus (and Us) (PBF9: 660-662, 670-675)
Camus: The absurdity of life, and whether meaning can be created.
Taylor: Life’s meaning comes from subjective fulfillment rather than ultimate purpose.
Criticism: Can meaning exist without a grand purpose?
Death (PBF9: 699-706)
Nagel: Death is bad because it deprives us of life’s experiences.
Baillie’s existential shock: Awareness of mortality influences how we live.
Should we fear death?
Epicurean view: Death is not bad because we won’t experience it.
Counterargument: Fear of the unknown is rational.
