Technology is our creation and the resulting array of physical things that are useful. There are two types of technology: Physical and metaphysical. Physical technologies are things like making a fire, doing agriculture and husbandry, and making tools and buildings and machines. Metaphysical technologies are ideas and beliefs. Things like (for example) religions are useful for raising good children and dealing with the forever unknowable vastness and neutrality of the universe. Mathematics is a kind of bridge between the realm of physical and metaphysical technologies. What is Morality? The creation and application of metaphysical technologies.
