A procatalepsis is a rhetorical figure or strategy in which the writer raises an objection and then immediately answers it; by doing so, the writer seeks to strengthen his argument by dealing with possible objections before his audience can raise counter-arguments.

Example:

• "It is difficult to see how a pilot boat could be completely immune to capsizing or plunging, but pilot boat design criteria must meet the needs of the industry and pilotage authorities."
