6.1.3 Arguments Against the Existence of God

Engaging with critical perspectives on theistic beliefs, we investigate the philosophical challenges to the existence of God, focusing on the argument from evil, the omnipotence paradox, and the argument concerning inconsistent revelations.

Argument from Evil

The argument from evil critically examines the reconciliation of God's defined attributes with the existence of evil in the world.

Logical Problem of Evil

  • Contradictory Attributes: Proposes that the traditional theistic attributes of God are incompatible with the observable existence of evil.
  • J.L. Mackie's Inconsistency: Argues it is logically inconsistent to hold all the following propositions as true:
    • God is omnipotent (all-powerful).
    • God is omnibenevolent (all-good).
    • Evil exists.
  • Epicurus’s Trilemma: Ancient formulation questioning whether God can be both willing to prevent evil and yet evil exists.

Evidential Problem of Evil

  • Inductive Reasoning: Suggests that the sheer quantity and severity of evil provide strong evidence against the existence of an all-loving and all-powerful deity.
  • William Rowe’s Fawn: Posits the existence of instances of intense suffering that an omnipotent, omniscient being could have prevented without thereby losing some greater good or permitting some evil equally bad or worse.

Responses to the Problem of Evil

  • Theodicies: Philosophical constructs that try to resolve the apparent contradiction.
  • Free Will Defence: Argues that moral evil is a necessary result of God's creation of beings with free will.
  • Soul-Making Theodicy: Suggests that human beings require the presence of evil for moral and spiritual growth.
  • Plantinga's Defence: Alvin Plantinga argues that God's creation of a world containing evil is logically possible if free will is considered.

Omnipotence Paradox

The omnipotence paradox questions the nature of an all-powerful entity's ability to perform impossible tasks.

Classic Paradox

  • Paradoxical Question: Can God create a stone so heavy that He cannot lift it?
  • Implications: Either God cannot create such a stone, or if He can, He cannot lift it, thus challenging the notion of being all-powerful.

Modern Formulations

  • McEar’s Paradox: If God can perform any action, could He make it such that He never existed?
  • Logical Limitation Defence: Suggests that omnipotence does not extend to performing logical impossibilities, thus maintaining the coherence of God's omnipotence.

Argument about Inconsistent Revelations

The argument from inconsistent revelations examines the discrepancies across various religious claims about God.

Inconsistent Doctrines

  • Exclusive Truth Claims: Many religions assert unique and often contradictory doctrines about the nature of God and reality.
  • Probabilistic Challenges: The argument suggests that the probability of any single set of doctrines being correct, among countless contradictory claims, is low.

Religious Diversity

  • Variety of Experiences: The wide spectrum of religious experiences and texts is seen as undermining the claim of any one tradition to exclusive truth.
  • John Hick’s Hypothesis: Proposes that religious experiences across different cultures are responses to one ultimate reality, which is interpreted differently due to cultural contexts.

Implications for Omnipotence and Benevolence

  • God's Intent: Questions the likelihood of a benevolent and omnipotent God allowing such widespread religious confusion that often leads to violence and intolerance.
  • Practical Consequences: If one true path exists, the argument suggests a deity interested in human salvation would make this path clear and unambiguous.

Culturally Contingent Beliefs

  • Geographic and Cultural Relativity: Notes that religious beliefs tend to correlate with specific geographic and cultural backgrounds, which would seem arbitrary for a universal truth ordained by a supreme deity.

Analysis of the Arguments

Critical Examination

  • Each of these arguments employs different strategies to challenge the existence of a deity, from deductive logical reasoning to inductive evidence-based approaches.
  • Philosophers utilise these arguments to scrutinise the coherency and plausibility of traditional theological claims, prompting debates that extend into ethics, metaphysics, and epistemology.

Philosophical Impact

  • These arguments have significantly shaped the landscape of religious philosophy, offering robust challenges to theistic positions and influencing countless philosophical works.
  • The arguments against the existence of God continue to be central topics in philosophy of religion courses and are essential for any student to engage with and understand.

Relevance in Contemporary Discourse

  • In modern philosophical and theological discourse, these arguments remain highly relevant, underpinning discussions on religious belief, agnosticism, and atheism.
  • They are integral in examining the existential and moral considerations of a world where the existence of a deity is questioned, influencing both individual beliefs and broader societal values.

FAQ

One might counter the argument from inconsistent revelations without appealing to a particular religious tradition by invoking the concept of religious non-realism. This perspective holds that religious statements and beliefs do not correspond to an external divine reality but instead reflect human expressions of moral ideals, communal identity, and individual psychology. From this viewpoint, the inconsistency of revelations is not a problem, as it is expected that different cultures and individuals will have varied expressions and experiences. Religious non-realism posits that these expressions serve practical, societal, or psychological purposes rather than describing a literal deity. Thus, inconsistent revelations may be seen as culturally relative narratives that shape ethical and social frameworks rather than factual claims about a universal divine entity.

Gratuitous evil refers to suffering that appears to serve no possible good and is beyond what would be necessary for any moral or spiritual development. The existence of gratuitous evil supports the argument from evil by challenging the notion that all suffering is part of a divine plan or has a greater purpose. If there is evil that seems utterly pointless or excessive, it becomes difficult to reconcile this with the existence of an all-loving and all-powerful God. This type of evil seems to contradict the idea of a benevolent deity who would prevent unnecessary suffering. Proponents of the argument from evil claim that the presence of gratuitous evil provides empirical evidence against the claim that an omnibenevolent and omnipotent God orchestrates the events of the world.

The notion that God cannot perform logically impossible actions is often seen as a limitation on omnipotence. However, many philosophers argue that true omnipotence does not require the ability to do the logically impossible. They suggest that omnipotence should be understood as the power to do anything that is logically possible. This definition preserves God's omnipotence because it does not diminish His power; rather, it acknowledges the coherence of His power within the bounds of logical consistency. Under this view, God remains omnipotent as He can actualise any state of affairs that does not entail a logical contradiction.

The argument from evil, especially when considering its impact on religious practices like supplication and prayer, presents a challenging implication: if God is not willing or able to prevent evil, then what is the efficacy of prayer in effecting change in the world? If evil persists despite an omnipotent deity's power to stop it, the act of supplication might seem futile. Some may argue that this challenges the sincerity or usefulness of prayer. However, defenders of religious practice might counter that prayer is not primarily about changing God's will or preventing evil, but rather about aligning oneself with God's purposes, finding solace, and expressing faith. Despite this, the argument from evil certainly prompts deep reflection on the nature and purpose of prayer within a religious life that acknowledges the persistent reality of suffering.

The Omnipotence Paradox, with its focus on whether an omnipotent being can create a task it cannot perform, indirectly touches upon the concept of divine simplicity, which suggests that God's attributes are not actually distinct from His essence. Divine simplicity holds that God does not have parts or components, and His characteristics, like omnipotence, are synonymous with His being. If God is simple in this way, then the paradox might be considered a misunderstanding of the nature of divine omnipotence. An omnipotent being, under divine simplicity, would not be subject to the paradoxical constraints of creating a stone too heavy to lift, as this implies a division within God's nature between His power to create and His power to lift, which divine simplicity denies. The Omnipotence Paradox challenges this by suggesting that if God can do all things, including the logically impossible, it would seem to contradict the unity of God's nature posited by divine simplicity.

Practice Questions

Evaluate the logical problem of evil as an argument against the existence of God.

An excellent answer would articulate that the logical problem of evil asserts an incompatibility between the existence of an omnipotent, omniscient, and omnibenevolent God and the presence of evil in the world. A comprehensive evaluation would acknowledge that while the argument presents a prima facie inconsistency within theistic claims, it also recognises the nuanced theodicies proposed by theologians and philosophers. For instance, the free will defence suggests that evil results from God granting humans free agency. Moreover, Alvin Plantinga's Free Will Defence is critiqued for not accounting for natural evil, demonstrating the argument's robustness in challenging the coherence of theistic attributes.

Discuss the significance of inconsistent revelations in the argument against the existence of a universal deity.

Inconsistent revelations present a significant empirical challenge to the claim of a universal deity by highlighting the diversity and contradiction of religious experiences and doctrines. An excellent answer would consider John Hick's hypothesis that different religions may respond to the same ultimate reality, offering a pluralistic perspective that undermines exclusive truth claims. The significance lies in the argument's ability to illustrate the improbability of any single religious tradition holding the complete truth, given the widespread and deeply rooted variations in religious belief. This diversity casts doubt on the existence of a universal deity who clearly communicates a singular divine will to humanity.
