Felix Adler,
Creed and Deed: A Series of Discourses
“ On pillars of intellect, Spinoza reared his system. Still, solemn, sublime like high mountains it towers upward, but is devoid of color and warmth, and even the momentary glow that now and then starts up in his writings, passes quickly away like the flush of evening that reddens the snowy summits of Alpine ranges. Spinoza's name marks a lofty peak in human history. He was a true man; no man more fully lived his teachings. If he describes the pursuit of knowledge as the highest virtue, he was himself a noble example of tireless devotion in that pursuit. ”
