Common sense plays a crucial role in understanding the foundations of human knowledge and the relationship between faith and reason. It serves as a foundational framework for understanding basic ontological truths and the natural world. Common sense allows individuals to grasp the existence of God, the nature of reality, and the moral law through intuitive understanding, which is essential for rational life.
In the context of faith and reason, common sense provides the basis for understanding dogmatic formulas. It ensures that these formulas, even when expressed in philosophical language, retain their objective meaning and are accessible to all, not just scholars. Common sense bridges the gap between the natural and supernatural realms, allowing for the integration of faith and reason. It acknowledges the importance of both natural reason and divine revelation, recognizing that while reason can lead to knowledge of God and the natural world, faith is necessary for understanding supernatural mysteries. Thus, common sense is integral to a comprehensive understanding of human knowledge and the interplay between faith and reason.
