Just as society is poised between individualism and collectivism, the individual is poised between body and mind.
It is innately harder to build an egalitarian relationship around mental activities. That’s because each person knows something about a different area of knowledge, and it’s hard to judge another person’s knowledge or to engage with it. If we do share the same discipline, one of us may know a great deal more than other, making us unequal.
If our project involves laying bricks, each of us can lay one hundred bricks. If our project invoves writing a book, it is innately harder to share the task of planning the book. Some people can do it; many cannot. Thus, physical connection is often more egalitarian, absent a high degree of skill and patience from one or both parties in a mental interaction.
