As I was scanning a new novel by Ben Marcus, and noted the dense prose, I realized there are two kinds of writers.
A.) Those who strive for clarity, who want the reader to know what they're saying. Who make it as easy as possible for the reader to understand the ideas expressed and to follow the plot threads.
B.) Those who are showing off, who wish every sentence to be as showy as possible, with the unknown reader a secondary consideration, if considered at all.
