Raimundus de Sabunde was a 15th-century Spanish theologian and philosopher, best known for his work "Creatio," published in 1434. This book explored the relationship between faith and reason, emphasizing the importance of natural knowledge in understanding divine truths. De Sabunde's ideas contributed to the development of scholasticism, a method of critical thought that sought to reconcile faith with reason. His work influenced later thinkers, including Rene Descartes, and remains significant in discussions about the interplay between science and religion.
