Abstract
In recent decades, scholars have shown a distinct new willingness to concede the important place of religion in the life and thought of the philosopher Franz Brentano. However, these studies are still dominated by the presumption that Brentano's life and thought are best understood according to a model of secularisation as a progressive waning of religion. This essay asks whether such a presumption is the best way of understanding the complex interconnections between various elements of his philosophical and religious ideas. It posits that a better appreciation of his position entails a confrontation with Brentano's historical imagination, and especially the structuring role of his approach to the history of philosophy as one manifesting regular cycles of decline and regeneration. Brentano's theory of the four phases of philosophy, though not the final word on how he viewed history, was nevertheless an exercise in thinking about the ways history accommodates various forms of progress and repetition. It was therefore a salutary means for thinking about the evolution of religion in ways that challenge any simple understanding of secularisation.
