Experienced utility: Utility theory from Jeremy Bentham to Daniel Kahneman

Utility is sometimes defined as being a way to summarise choice, and sometimes as the benefit we get from experience. In economics, the twentieth century saw the former definition supplant the latter. Recent research by Kahneman and colleagues has undertaken to resurrect the latter definition under the heading of “experience utility”. In this paper I give a brief history of the concept of experience utility, and examine three normative claims that have been made about it: that it avoids the problem of dependent utilities, that it can be measured from an invariant “zero point”, and that it allows intrapersonal comparison of utilities.     

对以边沁、密尔为代表的功利主义的分析批判

边沁的功利主义为苦乐原理、效果论和功利原则这样三个理论基点所构成。这是一个有着内在逻辑困境的三原理。苦乐原理由于没有进行内在的质的区分,为密尔所修正,但密尔的修正突出了苦乐原理与效果论的内在不一致;同时,密尔以自我牺牲来补充功利主义,又暴露了功利主义原则的内在矛盾。还有,密尔以平等权利来为功利主义的最大幸福原理辩护,恰恰表明功利原则并非是可以成为一个理论的基础性原则或终极原则。斯马特的行动功利主义则进一步暴露了功利主义的非正义性特性。功利主义的这样三个典范表明仅仅诉诸功利原则无从走出内在逻辑困境。布兰特援引认知理论以及道义论原则,笔认为这才使功利主义从其困境中走出。     

Bentham on animal welfare

Jeremy Bentham is often thought to have set the groundwork for the modern ‘animal liberation’ movement, but in fact he wrote little on the subject. A full examination of his work reveals a less radical position than that commonly attributed to him. Bentham was the first Western philosopher to grant animals equal consideration from within a comprehensive, non-religious moral theory, and he was a staunch defender of animal welfare laws. But he also approved of killing and using animals, as long as pointless cruelty could be avoided. The nuances of his position are best brought out by comparing it to that of Peter Singer, who draws considerably more radical practical conclusions. This is not primarily explained by competing formulations of utilitarianism, however, but by different empirical background assumptions about the lives of animals.

Reexamining Change Commentary on Paper by Jeremy Safran

Change—what prevents it, what nurtures it, and what maintains it—is a current that runs throughout the history of psychoanalytic theorizing. While knowledge, in the form of insight, remains an important antidote to repetition, awareness of the here-and-now process of the clinical experience has taken a new place in more recent theoretical understanding. In looking at these questions of change, this commentary offers some additional theories to those already expressed by Safran.
