The way we raise children is often metaphysical (experience, causality, and time), relegating nominalism (only particular objects exist) and historicism (the past is human nature) to the older or elites.
Yet, consider that what was once rare has become common, influencing the masses: the privilege of irony and atheism, once the domain of the elite, is now widespread. Today, we realize "-isms" (concepts) are merely shorthand labels, and history is arguable.
This has turned common sense into nonsense: irony and hypocrisy seem to govern daily life instead of earnest sincerity, moving our irony into the collective and hope into the private home.
