Arthur Krieger, PhD

I am an award-winning philosopher, bioethicist, and educator. I graduated from Temple University with a PhD in Philosophy in Spring 2026 and currently work as a medical ethicist at the Children's Hospital of Philadelphia (CHOP).

My areas of specialization are bioethics, philosophical psychology, and action theory. Much of my research aims to clarify the nature of addiction by combining philosophical resources with insights from neuroscience, psychiatry, psychology, and testimony from people with lived experience. I am one of the few philosophers currently arguing that addiction is a compulsion, in the sense that it often makes us incapable of doing otherwise. Building on my descriptive work, I also research various ethical dimensions of addiction, including moral responsibility for addictive behavior, the ethics of prescribing habit-forming drugs, and the ethics of public health approaches to addiction. I have broader research interests in bioethics, philosophy of medicine, normative ethics, and metaethics.

Teaching is a source of fulfillment and pride for me. I have an extensive record of excellence in teaching bioethics, normative ethics, social and political philosophy, philosophy of art, ancient philosophy, and modern philosophy.

In my spare time, I love to watch Star Trek with my wonderful wife and strangely human cat, taking frequent breaks to debate temporal mechanics (mostly but not exclusively with my wife).
