Well, an argument is a set[br]of statements that together comprise a reason for a further statement.
So, for example, we can consider one of your friend's responses[br]before as an argument.
Similarly, the third reason[br]also gives you a good reason to believe that[br]Monty won't be at the party.
If he's in Beijing, and[br]it's impossible to get here from Beijing in an afternoon,[br]then it's guaranteed that he won't be at the party.
The very best reasons for a belief make it certain, they guarantee it. Well, the reason that critical thinking is important is because,[br]since we're rational, we want our beliefs to be true.
Rational people want to have true beliefs, and they want not to have false beliefs.
We're gonna talk about three possible answers she could give.
First, she might say, "I can't stand him, and I want to have a good time." Second, she might say,[br]"Well, he's really shy, and he rarely goes to parties." And third, she might say, "He's in Beijing, and it's impossible to get here from[br]Beijing in an afternoon." The first response that she gives you does not give you a good reason to believe that Monty won't be at the party.
Now, it's worth saying something about how I'm using the term "good" here.
I'm not using it to indicate anything having to do with morality or ethics.
