The UVic Writer's Guide


Non Sequiturs


"It does not follow."

In this fallacy, the writer links two ideas or events that are not in fact related. TV commercials often depend on visual or implied non sequiturs:

"I own a fast, red sports car; women love me."

A non sequitur of causation (Post hoc, ergo propter hoc, "after this, therefore because of this") assumes that because one event followed another, it must have been the effect of the other:

"When it rained, my food processor broke."
