Abstract
If philosophy is to be faithful to her calling to serve truth and humankind, she must remain a pupil, open to the enrichment that other sciences bestow on her. This paper highlights some insights from J. H. Newman and C. S. Peirce that can shed light on our understanding of philosophy as a servant to the truth. Newman and Peirce are suitable guides for this discussion since both cultivated their intellect in various disciplines, which informed their philosophical contributions. It begins by exploring how Newman and Peirce conceived philosophy as a science. Then, it discusses their views on the unity of science, which further qualify their thoughts on philosophy. Finally, it enounces some consequences for the study of philosophy which their contributions suggest. Among many others, Newman and Peirce stand out as courageous defenders of the truth and have much to contribute to the timeless conversation of philosophy.
