"This Cosmology which contemplates GOD'S SPIRIT AND POWER IN ALL NATURAL PHENOMENA is alone worthy of His all-comprehensive greatness; only when we refer all forces and all phenomena of movement, all forms and properties of matter, to God, as the Author of all things, do we attain to that human intuition of God, and veneration of God, which really befits his immeasurable greatness. For 'in Him we live and move and have our being.' Thus the philosophy of Nature becomes in fact Theology. The worship of Nature becomes that true worship of God of which Göethe says:--'CERTAINLY THERE IS NO MORE BEAUTIFUL VENERATION OF GOD, THAN THAT WHICH ARISES FROM COMMUNION WITH NATURE IN OUR OWN BREASTS.' "GOD IS ALMIGHTY; he is the sole Author, the prime Cause of all things; that is, in other words, GOD IS THE UNIVERSAL CAUSAL LAW. God is absolutely perfect; he can never act otherwise than perfectly rightly, therefore he can never act arbitrarily or freely; that is to say, GOD IS NECESSITY. God is the sum of all forces; so also, therefore, of all Matter. Every conception of God, which separates him from Matter, opposes to him a sum of forces which are not of divine Nature; every such conception leads to Amphitheism, consequently to Polytheism. "Since MONISM demonstrates the UNITY OF THE WHOLE OF NATURE, it proves, likewise, that only ONE GOD exists, and that this God manifests himself in the collective phenomena of Nature. Since Monism grounds the collective phenomena of organic and inorganic Nature on the UNIVERSAL CAUSAL LAW, and displays them as the effects of 'active causes,' it shews at the same time, that GOD IS THE NECESSARY CAUSE OF ALL THINGS AND IS THE LAW ITSELF. Since Monism acknowledges no other beside the divine Forces in Nature, since it recognizes all laws of Nature as divine, it raises itself to the greatest and most elevated conception of which man, as the most perfect of all animals, is capable, to the conception of the UNITY OF GOD AND NATURE. 'Was wär' ein Gott, der nur von aussen stiesse, Im Kreis das All am Finger laufen liesse! Ihm ziemt's, die Welt im Innern zu bewegen, Natur in Sich, Sich in Natur zu hegen, So dass, was in Ihm lebt und webt und ist, Nie Seine Kraft, nie Seinen Geist vermisst.'"
