Review Questions

• How does Alvin Plantinga's concept of warrant challenge traditional internalist views of justification?
  • Plantinga's concept of warrant challenges traditional internalist views by suggesting that justification does not only rely on an individual's internal mental states but also on external factors. For him, a belief can be justified based on the proper functioning of cognitive faculties in an appropriate environment, meaning that factors outside one's awareness can play a crucial role. This shifts the focus from purely subjective criteria for justification to include objective conditions that support the reliability of those beliefs.
• Discuss how Plantinga's reformed epistemology addresses the rationality of belief in God without needing traditional evidence.
  • Plantinga's reformed epistemology posits that belief in God can be rational and justified independently of traditional evidential support. He argues that if a person's cognitive faculties are functioning properly within an environment conducive to producing true beliefs, then their belief in God can be warranted. This perspective challenges the view that faith must always be supported by empirical evidence, presenting a framework where such beliefs can stand as reasonable even without direct evidence.
• Evaluate the implications of Plantinga's externalism on our understanding of knowledge acquisition in modern epistemology.
  • The implications of Plantinga's externalism are profound for modern epistemology, as it broadens the understanding of how knowledge can be acquired and justified. By emphasizing external conditions and the proper functioning of cognitive processes, it allows for a more inclusive view that recognizes the influence of environmental and contextual factors in shaping our beliefs. This shift encourages further exploration into how social, cultural, and situational elements contribute to what we consider justified knowledge, challenging more traditional notions that prioritize individual reasoning above all else.
