When using a non-progressive eventive sentence in the present tense, it typically cannot describe a particular event: it often describes a habit or a generalization. E.g. if one says "John smokes a pipe", the listener would understand that this is a habit.
However, if a novel writer uses "John smokes a pipe" as a title of a chapter, the reader would understand that the chapter will describe a specific event where John smoked a pipe.
Why? Is there any name to this phenomena?
