Doing what is right is not optional if one wants to call oneself a professional in a globalized world. Acting within the general boundaries of ethically acceptable margins of society is a prerequisite of being a full and equal member of society. Acting within the specific ethical boundaries of a profession is likewise a prerequisite of being allowed to call oneself a member of this profession. Codes of conducts thus form an integral part of professions. 1 Some of these codes are more elaborate, others are quite general: most of them take in account the specificities of their profession. But are there universal principles in professional ethics that one has to adhere to independently of the profession and independently of the cultural-ethical background one belongs to if one truly wants to call oneself a global citizen? If a universal code of professional ethics is possible, it must be sufficiently general to cover most of the common scenarios a professional might find herself in and specific enough to give action guidance. Such a code, which this essay will develop, could form the basis of more specific codes of ethics for different professions. This chapter aims to develop principles, which 1 Hassan Bashir, associate professor at Texas A&M at Qatar, would even argue that a code of professional ethics is a constitutive element of what makes a profession.
