Individuals raised together but in isolation from the rest of the world sometimes develop a private language impenetrable to outsiders. Here's an example from this book: "What Planck and all other physicists thought disturbing about the derivation of his formula, was that it found no coherent impetus in the logical realm of scientific inquiry. His assertion of random intuition precedes the radicality of implication, because it was previously such an expanded conception of science that transformed man's capability of universal apperception, The final outcome of arbitrary creation integrated into empirically relevant models is, as one might imagine, that anything conceived of is anything experienced."
