Abstract

Many of the actual bioethical discussions start from the assumption that we have absolute dominance/disposition over our body. Based on the thesis of autonomy, control over one's own life and the freedom to do anything, at least with one's body, the goodness or legitimacy of acts such as suicide and euthanasia are often justified. Considering the last statements, this paper seeks to approach the question of the nature of the disposition –main attribute of dominion or property– over the body. It will be argued on the basis of Thomas Aquinas' theory and Immanuel Kant's exposition, often wrongly considered, in my opinion, as rival doctrines. The whole writing will be oriented to review the relations of the modern principle of autonomy with the problem of the morality of suicide.
