Career
Tännsjö has been a member of the medical ethics board of the faculty of medicine at Göteborg University and the ethical committee of Karolinska Institute. He is a member of the medical ethics committee of The National Board of Health and Welfare (the Swedish Government agency responsible for the supervision, evaluation and monitoring of social services, health care and medical services, dental care, environmental health, and control of communicable diseases). Furthermore, he is a member of the editorial board of Monash Bioethics Review, Tidskrift för politisk filosofi (Journal for Political Philosophy), Philosophical Papers, the ethics section of the web psychiatric journal Psychomedia, Bioethics and the Journal of Controversial Ideas.
Tännsjö is one of the few Swedish philosophers who is frequently heard in the public debate. His distinctly utilitarian ethical views have made him a controversial figure, notably within the medical establishment and for the Swedish Christian Democrats.Tännsjö has been a member of the Left Party since 1970, and was involved in writing the first party programme after the party dropped the communist label in 1990.
In 2001, he debated analytic philosopher and Christian apologist William Lane Craig on the subject, "If God Is Dead, Is Everything Permitted?".Tännsjö is a supporter of the Campaign for the Establishment of a United Nations Parliamentary Assembly, an organisation which advocates for democratic reformation of the United Nations, and the creation of a more accountable international political system.Recently, Tännsjö has published, in Swedish, an intellectual autobiography in two volumes. A review of the second volume by conservative historian of ideas Svante Nordin calls Tännsjö’s views on abortion, euthanasia and other issues in medical ethics “consistently crazy”. Nonetheless, Nordin praises Tännsjö's intellectual honesty and integrity, noting that he is “not primarily looking to show that [his] opponents are bad people, but rather that they are wrong. This means that he endeavors to present even the opponent's argument relatively clearly.”
