“Propaganda in favor of action that is consonant with enlightened self-interest appeals to reason by means of logical arguments based upon the best available evidence fully and honestly set forth. Propaganda in favor of action dictated by the impulses that are below self-interest offers false, garbled or incomplete evidence, avoids logical argument and seeks to influence its victims by the mere repetition of catchwords, by the furious denunciation of foreign or domestic scapegoats, and by cunningly associating the lower passions with the highest ideals, so that atrocities come to be perpetrated in the name of God and the most cynical kind of Realpolitik is treated as a matter of religious principle and patriotic duty.”

Context: For Shaw as for Goethe, the obligation to strive is a primary feeling: reason initiates nothing and would stop everything. Its use is to come after the fact and devise helpful justification of action. Culture, humaneness, spiritual grace, are not forced upon us by logic: they either are self-evident or pointless. There is, Shaw reminds us, no argument in behalf of moral conduct which would not equally well support immoral. But it is clearly impossible (and immoral) to exact moral conduct, cultivation, and grace from those whom circumstances force to lead sub-human lives. Therefore society must be reformed.

Section 7
The True Believer (1951), Part One: The Appeal of Mass Movements
Context: There is a fundamental difference between the appeal of a mass movement and the appeal of a practical organization. The practical organization offers opportunities for self-advancement, and its appeal is mainly to self-interest. On the other hand, a mass movement, particularly in its active, revivalist phase, appeals not to those intent on bolstering and advancing a cherished self, but to those who crave to be rid of an unwanted self. A mass movement attracts and holds a following not because it can satisfy the desire for self-advancement, but because it can satisfy the passion for self-renunciation.

Heschel made similar statements in earlier writings: The great insight is not attained when we ponder or infer the beyond from the here. In the realm of the ineffable, God is not a hypothesis derived from logical assumptions, but an immediate insight, self-evident as light. He is not something to be sought in the darkness with the light of reason. He is the light.

Context: In the realm of faith, God is not a hypothesis derived from logical assumptions, but an immediate insight, self-evident as light. To rationalists He is something after which they seek in the darkness with the light of their reason. To men of faith He is the light.
