The ultimate goal of human knowledge, according to Garrigou-Lagrange, is to understand and affirm the truths of both the natural and supernatural realms. His philosophy emphasizes the importance of common sense, which he defines as the natural and immediate intuition of fundamental metaphysical principles. These principles, such as the primacy of being over becoming, the principle of non-contradiction, and the reality of efficient causality, form the foundation for understanding both the created world and the divine reality.
Garrigou-Lagrange's philosophy contributes to achieving this goal by demonstrating that these principles are not only foundational for human reason but also lead to a deeper understanding of God and divine revelation. He argues that dogmatic formulas, which express the truths of faith, are grounded in these principles and are thus accessible to common sense. This approach ensures that the truths of faith are not isolated from human reason but are integrated into a comprehensive understanding of reality. By emphasizing the importance of common sense and the natural knowledge of God, Garrigou-Lagrange's philosophy provides a framework for achieving the ultimate goal of human knowledge: a unified and coherent understanding of the world and the divine.
