The author mounts a sustained critique of modern atheistic tendencies, arguing they negate religion, society, science, and art. Organized in two parts, the first analyzes atheism in France through the writings of Ernest Renan and the second traces philosophical antecedents in Germany. The critic contends that reducing God to an abstract ideal undermines genuine being and personality, that perpetual critical inquiry can become self-serving and verge on nihilism, and that these currents threaten both faith and the integrity of reason. The tone seeks correction of ideas rather than personal invective.
