All education springs from some image of the future. It springs from some implicit assumptions about what the future holds. When your kid comes home and says “Why do I need to learn algebra?” you don’t say, “Because our forefathers learned it.” You tell them that you’ll need it in the future. That assumes you know what the future has to hold. You’ll need algebra, or you’ll need marketing, or something. That presupposes that the parents and the curricula designers and the educators are making a set of assumptions about what the society, the colony of the world, is going to be like.
