I do not believe that it could never be justifiable to experiment on a brain-damaged human.

So why don't we make ourselves the last generation on earth? If we would all agree to have ourselves sterilized then no sacrifices would be required - we could party our way into extinction!

What one generation finds ridiculous, the next accepts; and the third shudders when it looks back on what the first did.

In some parts of the world, what you are doing is already apparent.According to the World Health Organization, the warming of the planet caused an additional 140,000 deaths in 2004, as compared with the number of deaths there would have been had average global temperatures remained as they were during the period 1961 to 1990. This means that climate change is already causing, every week, as many deaths as occured in the terrorist attacks on September 11, 2001.

Torturing a human being is almost always wrong, but it is not absolutely wrong.

It's also much clearer how much damage the occupation of Iraq is doing to America's reputation and prestige around the world; and that's just starting now to hit home in the United States.

I think ethics is always there; it's not always a very thoughtful or reflective ethics.
