The acquisition of knowledge from books provides an experience different from the Internet. Reading is relatively time-consuming; to ease the process, style is important. Because it is not possible to read all books on a given subject, much less the totality of books, or to organize easily everything one has read, learning from books places a premium on conceptual thinking - the ability to recognize comparable data and events and project patterns into the future. And style propels the reader into a relationship with the author, or with the subject matter, by fusing substance and aesthetics.
