This comprehensive volume presents a meticulous and updated examination of five pivotal philosophical arguments for the existence of God, which, despite their historical significance, have been largely overlooked in recent years. These arguments, rooted in the Aristotelian, Neo-Platonic, Augustinian, Thomistic, and Rationalist traditions, are rigorously defended and updated for a modern audience. The book also delves into the essential attributes of God, including unity, simplicity, eternity, omnipotence, omniscience, and perfect goodness, demonstrating that these characteristics are inherent to the divine being whose existence is established through these proofs. Furthermore, the text provides an exhaustive response to the various objections raised against these arguments, offering a robust and unparalleled defense of traditional natural theology. By reviving the intellectual legacy of philosophical giants such as Aristotle, Plotinus, Augustine, Aquinas, Leibniz, and others, this work seeks to reaffirm the conviction that God's existence can be definitively proven through reason alone, thereby challenging both atheism and the fideistic thinking that inadvertently bolsters it.
