ABSTRACT
Good medical practice and biomedical research conduct require doctors and scientists to think ethically. The practice of medicine is fundamentally good. To be an ethical person is the same as being a good person. I. Kant wrote that in making an ethical decision you should believe that the principle of your thinking is suitable to constitute not just what is right in the case, but in all cases. The emphasis of Kant in this sense is man's freedom to act in accordance with universal laws of nature and of morals. If one were to apply Plato's and Kant's philosophies in medical practice and research, the doctor must think for himself but at the same time think from the standpoint of everyone, but also think consistently. These rules prevent human individuals from making errors based on biases, personal desire and idiosyncrasies. The problem may be that the real meaning of 'good' has been lost due to common usage.
