"One correspondent, who is into psychology, notes that in his experience people who are hoplophobes are nearly always nutty in other ways, too. Hoplophobia [fear of guns], of course, is not simply an attitude but rather an aberration in which the sufferer clings to an idea which he himself knows to be unsound, such as the idea that inanimate instruments have a will of their own or that lawbreakers abide by the law."

But by far the greatest hindrance and aberration of the human understanding proceeds from the dullness, incompetency, and deceptions of the senses; in that things which strike the sense outweigh things which do not immediately strike it, though they be more important. Hence it is that speculation commonly ceases where sight ceases; insomuch that of things invisible there is little or no observation.
