Argument v. Contradiction
As the English Philosopher, Mont E. Python, observed, "An argument is a connected series of statements intended to establish a proposition."
Of course others disagreed. Most notably Other Man, who insisted: "No it isn't!.
To which Python replied, "Yes it is! 'tisn't just contradiction."
Other Man, of course, observed, "Look, if I 'argue' with you, I must take up a contrary position!"
"Yes," Python conceded, "but it isn't just saying 'no it isn't'."
To which Other Man rejoined, "Yes it is!"
And Python responded, "No it isn't!"
And it went back and forth like that for a bit, with many Strings arrayed and almost as many voids returned, until Python elaborated on his original observation thusly: "No it ISN'T! Argument is an intellectual process. Contradiction is just the automatic gainsaying of anything the other person says."
