I'd advice reading the famous article "More is different" by P. W. Anderson. It takes condensed matter physics as a counter example that knowledge is a pyramid, and that e.g. biology is just applied chemistry, which is just applied physics, which is just applied math and so on. I am glad social science people do not need to know quantum physics, nor medecine does group theory ; their fields are dense enough on their own sake ...

Actually, a universal understanding of the natural world would provide necessarily greater intuitive perspectives on what is necessary to be experienced universally by human minds. Create silos does more harm than good.
