I'm Just Saying: It Begs the Question

From Wikipedia:

Begging the question (or petitio principii, "assuming the initial point") is a logical fallacy in which the proposition to be proved is assumed implicitly or explicitly in the premise.

It begs the question, for example, to assert that "might makes right" because morality is defined by the victor.  But presenting a plan requiring a mansion and a yacht may raise the question of how to acquire such resources.  Rule of thumb: If you're about to say "It begs the question..." followed by an actual question, you probably mean "it raises the question."

I'm Just Saying: I Could Indeed Care Less

At the risk of sounding pedantic, I'd like to clarify something.

"I could care less."

You have some interest, however marginal.  You're saying that it is possible for you to care less than you currently do.  Your investment in the topic at hand is at some level greater than zero.

"I couldn't care less."

You are completely uninterested.  There is no way for you to care less than you currently do.  Your investment is zero, and the scale doesn't go negative.

I'm just saying.
