Title: Determinism, Free Will, and Moral Responsibility


1
Determinism, Free Will, and Moral Responsibility
  • Traditional threats to free will Fatalism
    (every event was meant). Predestination (every
    event is willed by God). Divine foreknowledge
    (every event is eternally known by God).
  • Determinism Every event is caused by a sequence
    of antecedent events.

2
Does determinism make free will an illusion?
  • Libertarianism We are free, determinism is
    false.
  • Hard determinism Free will is an illusion,
    our behavior is determined by genes and
    environment.
  • Compatibilism (soft determinism) Our behavior
    is causally determined but we are responsible for
    what we do. Our capacity to restrain present
    impulse to avoid predictable harm does not depend
    on escaping causal determination.

3
Obstacles to Incompatibilism
  • Libertarianism (incompatibilist indeterminism)
    Introduces a mysterious sort of agency that
    transcends physical laws. Implies that there can
    be no science of human behavior. Dualism (the
    belief that the self is immaterial) is no longer
    a viable position (no explanatory power,
    inconsistent with evolutionary theory,.)
  • Hard determinism (incompatibilist determinism)
    By regarding belief in free will as illusory,
    hard determinism eliminates moral responsibility
    and makes deliberation futile. But, the ability
    to deliberate is an evolutionary advantage, not
    an illusion.

4
The Evolution of Agency
  • The human brain is the product of six million
    years of evolution. The complexity of our brains
    provides us with the unique capacity for
    language. Linguistic ability enables us to
    anticipate future events and to deliberate about
    how to realize or avoid possible outcomes.
  • A rational agent is a utility maximizer. A UM
    deliberates about alternative outcomes, assigns
    an expected utility to each, and then attempts to
    realize the outcome with the highest expected
    utility. A UMs actions are caused and free.

5
Compatibilist Deliberation
  • Free action An uncompelled action that an agent
    chooses to perform as the result of a process of
    rational deliberation. Free choices are caused
    by a process of deliberation.
  • Here I stand, I can do no other. Luther

6
Religious Epistemology
  • Religious Rationalism The existence of God can
    be proven. Unbelief is irrational. Anselm,
    Aquinas, Paley.

Forget faith, brothers, Ive got logic.
7
Belief when the evidence is ambiguous.
  • Fideism Objective evidence for Gods existence
    is neither possible nor desirable it must be
    accepted on faith. Kierkegaard.
  • Voluntarism The existence of God cannot be
    proven or disproven, but religious belief is
    rational if our passions lead us to prefer the
    religious hypothesis. (James)

8
Ambiguity and religious belief
  • Religious empiricism The existence of God
    cannot be demonstrated, but reports of religious
    experience provide evidence for the existence of
    an Ultimate Reality.
  • Naturalism Naturalistic explanations (of the
    origin of the universe and human life, and of
    claims to religious experience) are superior to
    supernaturalistic explanations. Hence, religious
    belief is probably illusory.

9
The Five Ways of Aquinas
  • First Way change, motion.
  • P1. Everything moved is moved by something
    outside itself.
  • P2. Infinite sequence of movers- impossible.
  • \ A first, unmoved mover must exist God.

This argument is so moving!
10
2nd way of Thomas
  • Whatever exists has a cause.
  • Nothing can be the cause of itself.
  • Causes cant go back infinitely, for, if there
    was no first cause, there could be no subsequent
    causes.
  • \ There must be a first uncaused cause of the
    causal series. God.

11
Where true charity is found, God himself is
there. Thomas Aquinas
  • 3rd way Many things are contingent.
  • If everything is contingent, then once there was
    nothing.
  • \ Something must be necessary God
  • 4th Way Some things are sort of wise and not
    too pretty. Something is sort of wise by sharing
    in perfect wisdom. \ A supreme being exists.
    God

12
Teleology (5th way)
  • Nature operates according to regular patterns
    that allow life to flourish. It is no accident
    that the goal of flourishing is everywhere
    attained. An unconscious thing attains its goal
    only when guided by intelligence.
  • \ An intelligent force guides the universe.
    God.
  • Paley Find a watch, infer a watchmaker.
  • The human eye is more complex than a Rolex.
  • \ It is highly probable that a divine eye
    designer exists.

13
Disteleology
  • Natural selection and genetic mutation explain
    the slow evolution of the eye.
  • The big bang hypothesis explains the origin of
    our universe.

Are you sure the fossil record will confirm this?
14
Is the universe described by theism the universe
we inhabit?
  • Humes critique
  • The design argument rests on a weak analogy. The
    universe is unlike any product designed by
    humans. Living things differ from artifacts in
    relevant ways (begotten not made organic etc.)
  • We have no past experience of the origins of a
    universe.
  • The design argument fails to show that the
    designer is all powerful, morally good, or one
    god rather than a divine committee.
  • Wouldnt an all powerful creator display better
    craftsmanship?

15
J.S. Mills Natural Theology
  • The empirical evidence suggests that our universe
    was probably designed by a finite god who is
    benevolent but not clearly just. A god who
    allows evil, disease, ignorance, and suffering to
    attain some greater good is not omnipotent. If
    the creator is morally good that Being intended
    nature as a scheme to be amended, not imitated,
    by man. We must assist god in ameliorating the
    human condition.

16
The Problem of Evil
  • God is all powerful.
  • God is perfectly good.
  • Evil exists. Inconsistent statements
  • If God is all powerful, he could eliminate evil
    and suffering. If God is perfectly good he would
    wish to eliminate evil and suffering.

17
Theodicies
  • Deny omnipotence. Kushner When Bad Things Happen
    to Good People.
  • Deny the reality of evil Christian Science.
  • Cosmic harmony.
  • Free will requires evil (natural evil too? how
    much is required?)
  • Soul making A pilgrims long journey towards
    moral perfection

If evil is just an illusion then the illusion
that evil exists is an evil
18
Objections
  • Denying omnipotence solves the logical problem
    but leaves the question of Gods apparent absence
    unresolved.
  • Claiming that evil is illusion creates a new
    evil, viz., the widespread delusion that evil
    exists.
  • The extent of evil and suffering leaves one
    wondering, does the harmonious end justify the
    means?
  • Free will helps with moral evil but doesnt
    address natural evils.
  • How much suffering is required to shape a soul?

The Cosmic Casino
  • God is, or he is not. But to which side shall we
    incline? Reason cannot decide it at all. There
    is an infinite chaos that separates us. A game
    is being played, at the extremity of this
    infinite distance, in which heads or tails must
    come up. Let us weigh the gain and the loss, in
    taking heads that God exists. If you gain, you
    gain all if you lose, you lose nothing. Wager,
    then, That He is, without hesitation. (Blaise
    Pascal)

21
The Will To Believe
  • I. Our epistemic situation-- theoretic
    ambiguity (evidence for and against Gods
    existence is inconclusive).
  • II. Our existential situation
  • A. Importance- it matters greatly to us. A
    momentous hypothesis
  • B. Inevitability of choosing forced hypothesis.

22
William James concludes
  • When we are forced to decide on a momentous issue
    with inconclusive evidence, it is rational to
    follow our instincts and desires, to embrace the
    religious hypothesis.
  • John Hick wonders Is the will to believe a
    license for wishful thinking?
  • Can the argument support a right to believe if
    religious experience confirms that an Ultimate
    Reality exists?

23
Midterm Review
  • Pt I. Matching. Match the philosopher with his
    quote Thales, Democritus, Parmenides, Heraclitus
    (wk 1),Socrates (wk 2), Aquinas, (wk 3) Hume,
    Mill, Pascal, James (wk 4)
  • Part II. Short answer.
  • 1.Objection to piety definition (Euthyphro)(2)
  • 2. The Socratic Mission (2)
  • 3.James- skeptical balance (4)
  • 4.Religious ambiguity(3,4)
  • Pt. III. Essay (a) teleological (design)
    argument or (b) problem of evil.
  • Part IV. Multiple choice
  • 1. Definitions- libertarianism, hard
    determinism, compatibilism. 2. Problem of evil
    as objection to argument for Gods existence. 3.
    Why Plato opposes prayer/sacrifice piety. 4.
    Definition of rational agent. 5. Why Mill
    thinks God is finite. 6. Heraclitus main point.
    7. Famous Socrates quote.
