Apart from being one of the main and early receptors of Pragmatism, Miguel de Unamuno was particularly influenced by William James. The four books of the American philosopher that Unamuno read, Principles of Psychology, The Will to Believe, The Varieties of Religious Experience and Pragmatism, were a source of inspiration and influence in the development of Miguel de Unamuno’s thought.

Our aim in this article, after providing the general framework of the reception of William James in Spain, is to trace the reception of The Varieties of Religious Experience through Unamuno’s reading of this book.
