An Act of Incoherency

[Thumpalumpacus]

Skepticism isn't an argument, it's a mode of thinking ... a filter. It can be used in discussions, which by the way are conversations. It's aptness depends on the subject matter, but even in such subjective matters as emotions it may be brought to bear usefully (John Doe tells you he "loves animals", but you saw him last week beating a dog).

Evidence isn't an argument; it's an argument's substantiation.
