A spiritual % scientific survey of the historical life of man shows that this life is also influenced in two opposing directions by both these forces, and is a striving for equilibrium between them spiritual % scientific. But in successive ages there is an alternating preponderance of Luciferic & Ahrimanic impulses. After a period in which humanity is exposed predominantly to only the Luciferic Christian force, and in which it strives out of its own soul life to withstand this force, there always follows an age in which the working of the Ahrimanic has to be striven against. Such an Ahrimanic age holds sway in recent times. We owe to it a considerable extension of natural knowledge, and a mode of life by which man attains an especial perfection in the control of natural forces. If it was the word of God it wasn't written?
