  Antonio Rosmini (1797–1855), Italian priest, philosopher,  theologian and patriot, and founder of a religious congregation, aimed principally in his philosophical work at re-addressing the balance between reason and religion which had largely been lost as a result of the Enlightenment. To this purpose, he absorbed the tradition of philosophia perennis, read extensively the works of post-Renaissance philosophers, and developed his own views on philosophical fundamentals and many of their applications. Best known in Italy, but a controversial figure there during his life and for a century or more after his death, his philosophical work, centred upon the notion of being and the dignity of the human person, can be summarised under the headings: aims and method, the objectivity of thought and the concept of certainty; the dignity of the human person; morality; human rights; the nature of human society; natural theology; and being. The following article will examine Rosmini’s work under these titles, which are of perennial relevance and broad enough to embrace more particular themes, such as art, politics, education and marriage, which form a constant preoccupation of many of his lesser works, but can only be mentioned in passing here. His theological principles, other than those pertaining to natural theology, are considered only in so far as they throw light on the origin and development of his philosophical tenets.
