Roughly speaking, this hypothesis asks whether drug use causes some of the diseases officially associated with AIDS, such as immunodeficiency and Kaposi's sarcoma.

There exist thousands of Americans who have AIDS-defining diseases but are HIV negative.

The only goal of science is the honour of the human spirit, and a question in number theory is worth a question concerning the system of the world.

I object to a legal approach when settling questions of science or scientific behavior.

I am not here concerned with intent, but with scientific standards, especially the ability to tell the difference between a fact, an opinion, a hypothesis, and a hole in the ground.

What standards are upheld by the scientific community affect the community internally, and also affect its relations with society at large, including Congress.

Questions have arisen about the policing of science. Who is responsible for the policing? My answer is: all of us.
