Many people have a strong intuition that there is something morallyobjectionable about playing violent video games, particularly withincreases in the number of people who are playing them and the games'alleged contribution to some highly publicized crimes. In this paper,I use the framework of utilitarian, deontological, and virtue ethicaltheories to analyze the possibility that there might be some philosophicalfoundation for these intuitions. I raise the broader question of whetheror not participating in authentic simulations of immoral acts in generalis wrong. I argue that neither the utilitarian, nor the Kantian hassubstantial objections to violent game playing, although they offersome important insights into playing games in general and what it ismorally to be a ``good sport.' The Aristotelian, however, has a plausibleand intuitive way to protest participation in authentic simulations ofviolent acts in terms of character: engaging in simulated immoral actserodes one's character and makes it more difficult for one to live afulfilled eudaimonic life. 相似文献

Whilst some philosophical progress has been made on the ethical evaluation of playing video games, the exact subject matter of this enquiry remains surprisingly opaque. ‘Virtual murder’, simulation, representation and more are found in a literature yet to settle into a tested and cohesive terminology. Querying the language of the virtual in particular, I suggest that it is at once inexplicit and laden with presuppositions potentially liable to hinder anyone aiming to construct general philosophical claims about an ethics of gameplay, for whom assumptions about the existence of ‘virtual’ counterparts to morally salient phenomena may prove untrustworthy. Ambiguously straddling the pictorial and the performative aspects of video gaming, the virtual leaves obscure the ways in which we become involved in gameplay, and particularly the natures of our intentions and attitudes whilst grappling with a game; furthermore, it remains unclear how we are to generalise across encounters with the virtual. I conclude by briefly noting one potential avenue of further enquiry into our modes of participation in games: into the differences which a moral examination of playfulness might make to ethical evaluation. 相似文献

Although the word empathy only recently came into existence, eighteenth century philosopher, David Hume, significantly contributed to our current understanding
of the term. Hume was among the first to suggest that an empathic mechanism is the central means by which we make ethical
judgments and glean moral knowledge. In this paper, I explore Hume’s moral sentimentalism, and I argue that his conception
of empathy provides a surprisingly apposite framework for interpreting and addressing a current issue in practical ethics:
the moral significance of ultra-violent video games. Ultimately, I attempt to show that a Humean account of morality uniquely
explains the dangers of ultra-violent video gaming by elucidating a direct connection between playing such games and moral
harm. 相似文献
