In God, however, as the condition of His manifestation, lies, according to Boehme, the "eternal nature" or the mysterium magnum, which is as anger to love, as darkness to light, and, in general, as the negative to the positive.
As a theologian, Comenius was greatly influenced by Boehme.
His contributions to theological literature included treatises on Christian ethics and dogmatics, on moral philosophy, on baptism, and a sketch of the life of Jakob Boehme, who exercised so marked an influence on the mind of the great English theologian of the 18th century, William Law.
His favourite reading was poetry and mystical philosophy: Shakespeare, Dante, George Herbert, Goethe, Berkeley, Coleridge, Swedenborg, Jakob Boehme, Plato, the new Platonists, and the religious books of the East (in translation).
He retired in 1820, and soon after published one of the best of his works, Fermenta Cognitionis, 6 parts, 1822-1825, in which he combats modern philosophy and recommends the study of Boehme.
