This paper presents the medical practice according to the occidental philosophy (Platon, Spinoza, Kant). Relationships with the concept of "love" (eros, philia, agape) will be described, and the concept of dignity and autonomy as well. The reflection will focus on the end of life aspects. Although medicine cannot avoid morality, ethic, and deontology, it is also part of philosophy and must warrant the respect of human dignity, especially when a physician helps a patient to die.
