Man and God (El hombre y Dios) is the book upon which Xavier Zubiri was working when he died on September 21st, 1983. Fortunately, he left it almost complete, and that is the reason why the present text constitutes a systematic work and not a miscellany of fragments or essays. It is the first of his theology trilogy, the next two volumes of which are El problema filosofico de la historia de las religiones (The Philosophical Problem of the History of Religions), and Cristianismo (Christianity). Man and God has a profound relation of homogeneity with other books published by Zubiri: Sobre la esencia [English translation, On Essence, 1980], and the trilogy Inteligencia y Realidad , Inteligencia y Logos , and Inteligencia y Razon which together comprise Zubiri's major work, Inteligencia Sentiente [English translation, Sentient Intelligence, 1999]. In these works Zubiri sought to overcome the centuries-old conceptualism and idealism of Metaphysics (On Essence) and the Theory of Knowledge (Sentient Intelligence) though a new, unified vision of them capable of resolving the myriad problems accumulated over two and half millennia of intellectual effort.
