“Facts are constituted by older ideologies, and a clash between facts and theories may be proof of progress.”

Internet Encyclopedia of Philosophy
Context: The presentation of facts in logical form contributes to a confusion between discovery and proof. If the process of discovery were mere synthesis, any mechanical manipulator of prior partial concepts would have reached the insight and it would not have taken a genius to arrive at it.

Section 56
The True Believer (1951), Part Three: United Action and Self-Sacrifice
Context: The readiness for self-sacrifice is contingent on an imperviousness to the realities of life.... For self-sacrifice is an unreasonable act.... All active mass movements strive, therefore, to interpose a fact-proof screen between the faithful and the realities of the world.... by claiming that the ultimate and absolute truth is already embodied in their doctrine and that there is no truth nor certitude outside it.... To rely on the evidence of senses and of reason is heresy and treason. It is startling to realize how much unbelief is necessary to make belief possible. What we know as blind faith is sustained by innumerable unbeliefs.

Section 3 : Work Democracy versus Politics. The Natural Social Forces for the Mastery of the Emotional Plague;
Variant translation: The fact that political ideologies are tangible, active realities does not prove their necessity. The bubonic plague was an extremely potent social reality. But nobody would have argued that, because it existed, it was necessary and nothing should be done about it.
