“There is no logically necessary connection between events at different times; therefore nothing that is happening now or will happen in the future can disprove the hypothesis that the world began five minutes ago.”
The Analysis of Mind (1921), Lecture IX: Memory, p. 159
1920s
Context: There is no logical impossibility in the hypothesis that the world sprang into being five minutes ago, exactly as it then was, with a population that "remembered" a wholly unreal past. There is no logically necessary connection between events at different times; therefore nothing that is happening now or will happen in the future can disprove the hypothesis that the world began five minutes ago.

Context: The notions about the benefits of transgression in my last three novels are not ones I want to see fulfilled. Rather, they are extreme possibilities that may be forced into reality by the suffocating pressures of the conformist world we inhabit. Boredom and a deadening sense of total pointlessness seem to drive a lot of meaningless crimes, from the Hungerford and Columbine shootings to the Dando murder, and there have been dozens of similar crimes in the US and elsewhere over the past 30 years.
These meaningless crimes are much more difficult to explain than the 9/11 attacks, and say far more about the troubled state of the western psyche. My novels offer an extreme hypothesis which future events may disprove — or confirm. They're in the nature of long-range weather forecasts.
