A. When interpreting, choose the best possible interpretation and skip the minor mistakes of the opponent’s argument.
When the proposition or the argument is ambiguous, one should choose the best interpretation, that is, the most reasonable one.
If the argument contains some irrelevant problems or obvious mistakes in the argument, it is better to ignore them (if they are not crucial to the main point that the opponent is trying to make).
B. Assume the good will of the opponent’s intentions
To put it in more simple terms, if the interlocutor’s argument seems problematic, it is good to assume that it is unintentional on their part, as long as it is reasonable to do so.
It means that, if possible, one should give people the benefit of the doubt, and attribute issues in their arguments to a misunderstanding on their part, rather than to a malicious intent to deceive.
The third component might not seem essential, but it proves to be very useful in any discussions which are truth-oriented and especially in academic debates.
It might be overwhelming, misunderstood or even redundant in everyday life arguments, but some authors include it in the charitable interpretation.
C. Consider using a logically structured approach to the opponent’s argument.
It is highly beneficial, but very rare, to attempt to re-express your opponent’s position so clearly, logically structured, and fairly so your opponent might say: “Thank you for putting my thoughts so clearly!”
The component (c) might seem controversial however—sometimes putting one’s argument in a logical form may seem uncharitable to the interlocutor—especially if the discussion is not a purely philosophical debate between scholars.
Arguments which have a maximal commitment to truth would certainly benefit from this procedure (actually, this is a good practice of such debates), but in more common arguments this may seem uncharitable to the person, who is “being corrected,” for it suggests the superiority of one side.
