1. Appeals to authority.
"Genetic engineering is always morally wrong."
"Why do you believe that?"
"Dr. Smith told me."
"Who is he?"
"He's a professor of mathematics."
Clearly this is an appeal to authority.
"Moral relativism is hokey according to my friend."
"Who is he?"
"He's a philosophy major. He also says that his professors agree with him as well."
Here the line is kind of more blurry. At what point do we accept authority? Authority in a relevant field should be the deciding factor - or is it not? We know authorities are wrong sometimes - does this undermine us appealing to them?
2. Tu quoque and bias.
"It's morally wrong to use animals for food and clothing."
"But you are wearing a leather jacket and eating sausage!"
The fact that a person makes inconsistent claims does not make any particular claim he makes false.
However, we also want to point out bias in authorities. Scientists at the Coca Cola Company have determined that Coca Cola is the most healthy soda brand out there on the market. But we wouldn't be inclined to trust that, because they're biased! Or should we trust them anyway? Where do we draw the line?
