Peter De Vries said this quote

Stein resented the sedative power of religion, or rather the repose available to those blissfully ignorant that the medicament was a fictitious blank. In this exile from peace of mind to which his reason doomed him, he was like an insomniac driven to awaken sleepers from dreams illegitimately won by going around shouting, 'Don't you realize it was a placebo!' Thus it seemed to me that what you were up against in Stein was not logic rampant, but frustrated faith. He could not forgive God for not existing.
