  • In sum, if it seems that I have simply misunderstood what Kant and deontology are all about,
    it's because I am advancing an alternative hypothesis to the standard Kantian/deontological understanding
    of what Kant and deontology are all about. I am putting forth an empirical hypothesis
    about the hidden psychological essence of deontology, and it cannot be dismissed a priori
    for the same reason that tropical islanders cannot know a priori whether ice is a form of water.

    1. We are currently in the Holocene epoch of the Quaternary period of the Cenozoic era of the Phanerozoic eon
    2. We share our capacities for moral reasoning, moral judgment, and moral decision-making with our Pleistocene epoch hunter-gatherer ancestors
