From the translator's introduction:
"While much of this book is Edgar's attempt to defend his older brother Bruno, the founder and primary exponent of Young Hegelian critique, against attacks from conservative Christian authorities and apologists, the greater part - and the main message - is straightforward political philosophy, written in a brash, accessible, sarcastic, no-holds-barred style - not at all ponderous, as we might have expected from a German author. His overarching theme is that faith is justified if and only if it is faith in reason and in the power of the human intellect, but never if it is faith which defies or denies reason, logic, history, nature, the human spirit, or especially science. Unreflective conformity with the faith of others or with the dictates of the ecclesiastical or sociopolitical order is even worse."
