  Austin called these characteristic aims of speech acts perlocutions (1962, p. 101). I can both urge and persuade you to shut the door, yet the former is an illocution while the latter is a perlocution. How can we tell the difference? We can do so by noting that under the right conditions, one can urge just by saying and speaker meaning, “I hereby urge you to shut the door,” while there are no circumstances in which I can persuade you just by saying, “I hereby persuade you to shut the door.” A characteristic aim of urging is, nevertheless, the production of a resolution to act (1962, p. 107). Cohen (1973) develops the idea of perlocutions as characteristic aims of speech acts.
