“No, she said, with great certainty, because now they had facts, and facts changed everything. Without them, you had nothing, a void. But produce facts – provide names, dates, orders, numbers, times, locations, map references, schedules, photographs, diagrams, descriptions – and suddenly that void had geometry, was susceptible to measurement, had become a solid thing. Of course, this solid thing could be denied, or challenged, or simply ignored. But each of these reactions was, by definition, a reaction, a response to some thing which existed.”

Fatherland, de Robert Harris.
