This paper establishes a Kantian duty against screen overexposure. After defining screen exposure, I adopt a Kantian approach to its morality on the ground that Kant’s notion of duties to oneself easily captures wrongdoing in absence of harm or wrong to others. Then, I draw specifically on Kant’s ‘duties to oneself as an animal being’ to introduce a duty of self-government. This duty is based on the negative causal impact of the activities it regulates on a human being’s mental and (...) physical powers, and, ultimately, on the moral employment of these powers. After doing so, I argue that the duty against screen overexposure is an instance of the duty of self-government. Finally, I consider some objections. (shrink)

Resumen Es muy conocida la opinión de Kant en relación con la inmoralidad del suicidio. De ahí que, muchos autores lo consideren como un prohibicionista absoluto. Sin embargo, no hay hasta el momento un análisis puntual sobre la definición metafísica-conceptual del suicidio en la teoría kantiana. En este artículo propongo entender el suicidio en Kant como una muerte física, total, autorreferencial, voluntaria e inmoral. Esta definición contrastará con la privación de la vida, la cual no implica inmoralidad. Al ser voluntarios, (...) tanto la privación de la vida, como el suicidio son actos racionales y entendibles a partir de las máximas de acción. La inmoralidad del suicidio sólo surgirá al considerar la primacía de las razones morales por encima de razones no morales.It is common knowledge theposition of Kant regarding the immorality of suicide. Several authors attribute him an absolutist-forbidden criterion. Nerveless, there is no extended analysis about the metaphysical-conceptual definition of suicide in Kantian theory. In this paper I hold that suicide in Kant can be defined asphysical death, full, self-referential, voluntary, and immoral. This definition conflicts with the definition of deprivation of life which is not immoral. As voluntarily acts, both suicide and deprivation of life are rational acts that can be understood as maxims of action. The immorality property of suicide is due to the primacy of moral over non-moral reasons. (shrink)
