Review Questions

• How does Alvin Plantinga's concept of warrant differ from traditional notions of justification in epistemology?
  • Alvin Plantinga's concept of warrant extends beyond traditional justification by focusing on what makes a belief not just justified but also properly basic. While justification often requires evidence or reasons for a belief, warrant involves the idea that a belief is formed under the right conditions and reliably leads to truth. This means that warranted beliefs can exist even without supporting evidence, especially in the context of religious beliefs, where Plantinga argues that belief in God can be warranted without needing external justification.
• Discuss how Plantinga's Reformed Epistemology challenges the evidentialist view regarding belief in God.
  • Plantinga's Reformed Epistemology directly challenges the evidentialist view by positing that belief in God can be rational and justified without any evidence. He argues that certain beliefs can be considered 'properly basic', meaning they are foundational and do not require external validation. This perspective asserts that individuals can hold beliefs about God similarly to how they hold beliefs about other fundamental experiences, like the existence of other minds or the external world, thus providing a philosophical basis for faith that does not depend on evidentiary support.
• Evaluate the implications of Plantinga's free will defense for the problem of evil and its influence on contemporary discussions in philosophy of religion.
  • Plantinga's free will defense significantly impacts discussions around the problem of evil by suggesting that the existence of evil does not contradict the existence of an all-good, all-powerful God. He posits that moral good requires free will, and therefore, God allows evil as a necessary condition for human freedom. This argument has influenced contemporary philosophy by reframing how theologians and philosophers address the tension between divine omnipotence and the presence of suffering in the world, leading to richer dialogues around ethics, morality, and faith.
