Review Questions

• How does epistemic modality relate to the concept of possibility in expressing what might be true based on knowledge?
  • Epistemic modality plays a crucial role in articulating possibility by framing statements around what is known or believed. It allows us to evaluate propositions not just by their truthfulness but also by how confident we are about their validity based on available information. This means that what is possible can vary greatly depending on an individual's perspective and knowledge base, highlighting the subjective nature of assessing possibility.
• In what ways does deontic modality challenge our understanding of possibility regarding actions and obligations?
  • Deontic modality introduces a nuanced view of possibility by examining it through the lens of moral obligations and permissions. This perspective reveals that just because something is possible does not mean it is permissible; for instance, an action may be possible yet deemed morally wrong or prohibited by societal rules. Thus, deontic modality enriches our understanding of possibility by integrating ethical considerations into the evaluation of actions and choices.
• Critically assess how dynamic modality affects our perception of possibility in decision-making processes.
  • Dynamic modality significantly shapes our perception of possibility by focusing on the capabilities and potential actions available to agents within specific contexts. This framework helps us understand how individuals navigate choices based on their abilities, resources, and situational constraints. By recognizing that possibilities can change depending on an agent's circumstances, we gain insight into how decisions are made and the importance of context in determining what actions are feasible or attainable.
