Ideology and methodology

Bioethicists often focus on using philosophy to help analyze issues, and philosophical bioethicists such as Peter Singer tend to treat the field as a branch of moral or ethical philosophy. However, this approach is sometimes challenged, and bioethics is becoming increasingly interdisciplinary. Many bioethicists come from backgrounds outside of academic philosophy, and some even claim that the methods of analytic philosophy have had a negative effect on the field's development.

Religious bioethicists have developed rules and guidelines on how to deal with these issues from within the viewpoint of their respective faiths. Some Western secular bioethicists are critical of the fact that these are usually religious scholars without an academic degree or training in disciplines that pertain to the issues, such as philosophy (wherein the formal study of ethics is usually found), biology or medicine.
Many religious bioethicists are Jewish or Christian scholars. However a growing number of religious scholars from other religions have become involved in this field as well. Islamic clerics have begun to write on this topic. Muslim bioethicists include Abdulaziz Sachedina, at the University of Virginia in Charlottesville. There has been some criticism by liberal Muslims that only the more religiously conservative voices in Islam are being heard on this issue.

In the case of most non-Western cultures a strict separation of religion from philosophy does not exist. In many Asian cultures, there is a lively (and often less dogmatic, but more pragmatic) discussion on bioethical issues. The discussion often refers to common demographic policies which are criticised, as in the case of China. Buddhist bioethics, in general, is characterised by a naturalistic outlook that leads to a rationalistic, pragmatic approach. Buddhist bioethicists include Damien Keown. In Africa, and partly also in Latin America, the debate on bioethics frequently focus on its practical relevance in the context of underdevelopment and (national or global) power relations.
