Hitler's selective readingor nonreadingof the pseudo-theological texts in his library makes those books he did read, and especially those in which he left marginalia, all the more significant. Here is where the Hitler Library is most useful. In the Fichte volumes given to him by Riefenstahl, I encountered a veritable blizzard of underlines, question marks, exclamation points, and marginal strikes that sweeps across a hundred printed pages of dense theological prose. Where Fichte peeled away the spiritual trappings of the Holy Trinity, positing the Father as "a natural universal force," the Son as the "physical embodiment of this force," and the Holy Ghost as an expression of the "light of reason," Hitler not only underlined the entire passage but placed a thick vertical line in the margin, and added an exclamation point for good measure.
