Can the thinking of a single philosopher be so influential as to change the fundamental values of a society and lead to tremors of transcontinental proportions, like the economic crisis that began in 2007?

These days, we are free to believe anything and to be anything, at least in theory. However, if we gave history a closer look, we would realise that it is not beneficial for us to believe or be just anything. We agree with the biblical exhortation, often distorted by popular lore: "...test them all; hold on to what is good" (1 Thessalonians 5:21).
