Philosophy Reformed and Improved in Four Profound Tractates is a 17th-century philosophical work by Oswald Croll, first published in 1657. This treatise is divided into four sections, each exploring fundamental aspects of nature, creation, the human soul, and ethics. Croll integrates the teachings of Paracelsus, particularly his “Philosophy to the Athenians,” to present a comprehensive view of the natural and spiritual worlds.

The first tractate delves into the mysteries of nature, emphasizing the interconnectedness of the physical and spiritual realms. Croll discusses the role of alchemy and the importance of understanding the natural world to comprehend divine truths. He posits that true knowledge arises from the synthesis of empirical observation and spiritual insight.

In the subsequent tractates, Croll examines the creation of the universe, the nature of the human soul, and the path to ethical living. He draws heavily from Paracelsus’s philosophy, which stresses the unity of the cosmos and the divine presence within all things. Croll advocates for a holistic approach to philosophy, one that harmonizes scientific inquiry with spiritual wisdom.

Philosophy Reformed and Improved offers a profound synthesis of alchemical thought, Christian theology, and Renaissance humanism. Croll’s work reflects a deep reverence for the ancient traditions of knowledge while striving to adapt them to the evolving intellectual landscape of his time. His treatise serves as a bridge between medieval scholasticism and modern scientific thought, advocating for a philosophy that is both rooted in tradition and open to new discoveries.
