醫學與道德的關係早在醫學鼻祖希布克底的時代就被提出，並在其醫學誓言裡強調醫事人員道德情操的重要性。隨著人類知識的進步，我們已確認人不只是一個「體」的存在，更是「靈」與「體」的綜合。在此認識下，醫學的目的不只是疾病的診治，也要使人性提升，來促進全人的健康。換句話說，醫生所診治的病人便不是一個物質的軀體而已，更是一個尊嚴的生命，因之就應有特別的倫理原則來做為醫療關係的基礎，以促進靈體智的健全。本文列舉四個世界衛生組織的醫學宣言，窺視醫學與道德的關係外，也提出四個個案（兩個西方、兩個臺灣）來檢討醫學與道德的關係。要使醫學的進步造福人群，醫學絕不能在醫學倫理的範疇之外來實踐。醫學缺乏了倫理原則，就會像失控的車子，對人類造成難以復原的傷害。為了往後臺灣全人的健康，與社會的福祉，我們決不能不去重視醫學倫理課程的重要性。

　　　　　The preamble to the constitution of the World Health Organization states that the purpose of medicine is to promote complete physical, mental and social well-being. Since medicine promotes health over illness and good over evil, it cannot be amoral. In other words, medicine and morality must go side by side. The purpose of this paper is to show that medicine without morality can be crippling and even blinding. In addition to discussing why medical morality is needed, four case studies (two western and two Taiwanese) are also discussed. Health care is undergoing changes that are more rapid and more dramatic than ever before. These include advances in medical technologies and changes in governmental policies such as medical insurance. Never before has there been such a need for careful reflection of the impact of these changes upon health-care quality and medical ethics.
