Christianity and Philosophy
Arguments for the Existence of God
● Ontological Argument:
○ Concept: A priori argument suggesting that the very concept of God as
the greatest being implies His existence.
○ Anselm's Argument: "God is that which nothing greater can be
conceived. That which exists in reality is greater than that which exists
only in the mind. Therefore, God must exist in reality."
○ Criticism: Gaunilo's Island analogy, Kant's objection that existence is
not a predicate.
● Cosmological Argument:
○ Concept: A posteriori argument that asserts everything that exists has
a cause, and this leads to the necessity of a first cause (God).
○ Aquinas' Argument: Aquinas’ Five Ways, particularly the Argument
from Motion and Causation, conclude with a necessary being (God).
○ Criticism: Hume’s criticism of causality and the possibility of an infinite
regress.
● Teleological Argument:
○ Concept: Also known as the Design Argument, it posits that the order
and complexity of the universe indicate a designer.
○ Paley's Watchmaker: The analogy of finding a watch and inferring a
watchmaker applies to the universe.
○ Criticism: Hume’s critique of the analogy and Darwin’s theory of
evolution challenging the need for a designer.
● Moral Argument:
○ Concept: Asserts that the existence of objective moral values points to
a moral lawgiver (God).
○ Kant's Moral Argument: God is necessary for the existence of moral
law and the ultimate justice (summum bonum).
○ Criticism: Euthyphro Dilemma: Is something good because God
commands it, or does God command it because it is good?
Religious Experience
, ● Types of Religious Experience:
○ Mystical Experiences: Direct and intense encounters with the divine,
e.g., St. Teresa of Avila’s visions.
○ Conversion Experiences: Radical change in belief or lifestyle, e.g.,
Saul's conversion on the road to Damascus (Acts 9).
○ Corporate Religious Experiences: Experiences shared by groups,
e.g., Pentecost (Acts 2).
● Arguments from Religious Experience:
○ Swinburne’s Principle of Credulity: We should generally trust our
experiences unless we have a reason to doubt them.
○ Swinburne’s Principle of Testimony: The experiences of others
should be considered credible unless there’s evidence against them.
● Criticisms:
○ Psychological Explanations: Freud suggested religious experiences
are illusions or projections of the human mind.
○ Sociological Explanations: Durkheim argued that religious
experiences are a reflection of societal needs rather than divine
encounters.
Problem of Evil
● Logical Problem of Evil:
○ Concept: If God is all-powerful, all-knowing, and all-good, how can evil
exist?
○ Epicurus' Paradox: “Is God willing to prevent evil, but not able? Then
he is not omnipotent. Is he able, but not willing? Then he is malevolent.
Is he both able and willing? Then whence cometh evil?”
○ Theodicies:
■ Augustinian Theodicy: Evil is a privation of good, resulting
from human free will and the Fall.
■ Irenaean Theodicy: Evil exists for soul-making, allowing
humans to develop and grow morally.
● Evidential Problem of Evil:
○ Concept: The amount and kinds of evil in the world (e.g., natural
disasters, moral evil) make God’s existence unlikely.
○ Responses:
■ Free Will Defense: God gave humans free will, and this
necessarily includes the potential for evil.
■ Greater Good Defense: God allows evil to bring about a
greater good that wouldn’t be possible without it.
● Process Theodicy:
○ Concept: God is not omnipotent in the traditional sense but is part of
the process of the universe, suffering and evolving with it.
○ Criticism: Raises questions about the nature of divine power and the
adequacy of such a God.
