Substance vs. Structure

Someone asked me an interesting question. “How do our cognitive abilities get any structure without adhering to some sort of ideology?” My answer: Structure and substance are too different things. A book can give you a structure, we read from left to right, from top to bottom etc. What I am concerned with is what we write on the pages not how we read. The common structure of a book can hold the ideologies Marx, Christianity, Islam or Communism and Capitalism. Anyone can write anything on a page, the reader must read with discernment.
