365 Days with Nicholas of Cusa

Enter the mystery where knowing ends and wisdom begins.

365 Days with Nicholas of Cusa: Not-Knowing, Divine Infinity, and the Transformation of the Mind invites you into the daring spiritual vision of one of Christianity’s most original thinkers—a cardinal, philosopher, and mystic who stood at the threshold between the medieval world and modern consciousness.

Nicholas of Cusa taught that the highest form of knowledge is not mastery, but humility. He called it learned ignorance: the recognition that God is infinite, and that all concepts, images, and doctrines fall silent before divine mystery. Far from skepticism or resignation, this not-knowing opens the mind to transformation. It frees reason from false certainty and awakens a deeper mode of seeing—one capable of holding paradox, unity, and transcendence together.

This daily devotional companion distills Cusa’s profound insights into a year-long journey of reflection. Drawing from his major works—especially On Learned Ignorance—each meditation invites the reader to loosen rigid categories, to contemplate the coincidence of opposites, and to discover God not as an object of thought, but as the infinite horizon in which all thinking takes place.

In this book you will find:

• Daily meditations grounded in authentic medieval Christian theology and mysticism

• Reflections on learned ignorance as a spiritual discipline rather than a limitation

• Guidance for living faithfully with paradox, uncertainty, and intellectual humility

• A contemplative path that integrates reason, faith, and interior transformation

This book is for readers drawn to contemplative Christianity, apophatic theology, and a spirituality that does not reduce mystery to easy answers. Whether approached as philosophy, prayer, or daily discipline, these reflections offer a steady invitation to think less defensively—and to see more deeply.

About the Author

365 Days Press in collaboration with Ruth Marianne Calder
Ruth Marianne Calder is a Scottish independent contemplative writer whose work is shaped by long engagement with medieval Christian thought, apophatic theology, and the discipline of unknowing. Rather than treating theology as a system to be mastered, she approaches it as a lived orientation of the mind and heart—one formed through sustained reading, silence, and interior attention. Her writing does not seek to resolve mystery or reduce it to clarity, but to help readers remain with it faithfully, learning how to dwell within paradox, humility, and openness without anxiety or false certainty.
