It seems that Taiwan has become a member of modem society, but professional ethics still could not be developed very well. According to the Western experience, professional ethics is the main basis of the rise of modem society. In Taiwan, profession and professional ethics is been distinct very clear. Most of professionals are not took their job as vocation. They spend much of time in the field of occupation, but not could recognize it. We force our self to identify it. What is the professional ethics? I think it is not only a kind of moral, but also a kind of right, and practice it by discourse and communication. However, Taiwan's education of professional ethics ignore it, still treat it just a kind of moral. But it is formed by long historical process in the Western. We could not so naïve to think it will be developed naturally in Taiwan.
