From Abracadabra to Zombies
Robert T. Carroll, Ph.D.
I was a full-time teacher in the philosophy department at Sacramento City College from 1977 until my retirement in 2007. I received my Ph.D. from the University of California at San Diego in 1974. My doctoral dissertation was done under the direction of Richard H. Popkin and was entitled The Common-Sense Philosophy of Religion of Bishop Edward Stillingfleet (1635-1699). It was published by Martinus Nijhoff, The Hague, in 1975. I began publishing on the WWW in 1994. Since then I have posted several thousand articles on my website skepdic.com.
I began investigating controversial beliefs about 50 years ago and posted my first articles on the Internet more than 20 years ago. My main research interests have been in philosophy of religion, the history of 17th century philosophy, epistemology, skepticism, critical thinking, and the psychology of belief. I have applied these interests to a wide range of topics. I am interested not only in what people believe, but why we believe what we do. I am especially interested in the cognitive biases and logical fallacies that unconsciously drive much human thinking on subjects we care most passionately about.
My textbook Becoming a Critical Thinker was published by Pearson in 2000. A second edition was published in 2005. The book is available online for free:
1. Critical Thinking
2. Language and Critical Thinking
4. Identifying Arguments
5. Evaluating Arguments
6. Evaluating Extended Arguments
7. Sampling and Analogical Reasoning
8. Causal Reasoning
9. Science and Pseudoscience

I was invited by James Randi to speak at the first Amazing Meeting in 2003 and to conduct a workshop on critical thinking at the 5th meeting in 2007. In 2003 I gave an invited talk at the CSICOP conference on Frauds and Hoaxes. In 2004 I gave a talk to the Irish Skeptics in Dublin, Ireland, on the subject of the scientific proof for the paranormal. In 2010, I was elected a fellow of the Committee for Skeptical Inquiry (CSI).
In May 2014 I was diagnosed with pancreatic neuroendocrine cancer (not to be confused with pancreatic adenocarcinoma: for a short description of the difference between these two types of cancers see Lauren's blog. About 5% of cancers of the pancreas are neuroendocrine. About 14.5 million Americans alive today have or have had cancer. About 120,000 of those have neuroendorine cancer and 6.4% of those are pancreatic.)
