 We can say that arguments are (i) conversational traffic jams—(ii) gridlock with a lot of honking and little movement; (iii) conversational traffic accidents; (iv) wrong turns, or (v) detours, or (vi) dead ends or (vii) roundabouts on the streets of discourse; or should we have said that they are (viii) short cuts to the truth at the end of the road; maybe (ix) they are long and winding roads to nowhere; or, instead, we can conceive of arguments as (x) intellectual one way roads to their conclusions although maybe they are really (xi) one-lane roads but with two-way traffic. More positively, they can be thought of as a case of (xii) a merging traffic of ideas or even better as (xiii) conceptual roads under construction. (Cohen 1995: 184)
