Meister Eckhart was a 14th-century theologian who became an influential preacher, mystic, and philosopher, and one of the most profound thinkers of the Middle Ages. Everywhere his teaching and preaching left a deep mark and the importance of Eckhart in the history of scholastic philosophy is considerable. The fundamental idea of Eckharts philosophy is that of the Absolute or Abstract Unity conceived as the sole real existence. His God is the [Theo Agnosto (Unknown God)] of the neoplatonists: He is absolutely devoid of attributes which would be a limitation of His Infinity. God is incomprehensible; in fact, with regard to our limited intelligence, God is the origin and final end of every being.
