QUOTE : With the Internet, our marketplace of ideas became exponentially bigger and freer than ever, it’s true. Thomas Jefferson said he’d “rather be exposed to the inconveniences attending too much liberty than those attending too small a degree of it”—and it would all be okay because in the new United States “reason is left free to combat” every sort of “error of opinion.” However, I’m inclined to think if he and our other democratic forefathers returned, they would see the present state of affairs as too much of a good thing. Reason remains free to combat unreason, but the Internet entitles and equips all the proponents of unreason and error to a previously unimaginable degree. Particularly for a people with our history and propensities, the downside—this proliferation and reinforcement of nutty ideas and false beliefs, this assembling of communities of the utterly deluded, this construction of parallel universes that look and feel perfectly real, the viral appeal of the untrue—seems at least as profound as the upside.
