Interpersonal Intellectual functions and Persuasion

“A person may seek principles not only to test his own judgement or give it more support but also to convince others or to increase their conviction. To do this he cannot simply announce his preference for a position; he must produce reasons convincing to the others. Reasons may be very particular, but they also can be general considerations that apply well to a wide range of cases and point to a particular judgement in this instance. If these judgements in the other cases are ones the other person already accepts, then the general reasoning will recruit these cases as evidence and support for the judgement proposed in the present case. Principles or general theories thus have an interpersonal intellectual function: justification to another.”
