Question: What's right or wrong about calls for "moderation"? Many things are black and white, but sometimes moderation seems like the right course. For example, you don't want to stuff yourself full of every food that strikes your fancy, nor deny yourself foods that you enjoy. So you should eat moderately. Similarly, you don't want to agree to or deny every favor asked by a friend, but rather do some moderate amount. Is moderation a good guide in some areas of life?

Question: Isn't it wrong to be a "black and white" thinker? To a lot of people that is not a good trait. Life isn't black and white. Black and white thinking limits you. It closes doors instead of opening them and it also closes minds. In the case of gray, you can give and take. Why is black and white thinking a necessary part of Objectivism? Shouldn't common contradicting viewpoints be welcome in a healthy discussion?
