What are some criticisms of Peter Singer's philosophy?
gpt
* Martha Nussbaum's Capability Approach 

* Alasdair MacIntyre's *After Virtue* in which he likens the principle of utility to a conceptual fiction that might produce beneficial actions, but a fiction nonetheless. 

* Eva Kittay challenges Singer's attitude towards the euthanasia of disabled infants in a 28 day period as a mother of a profoundly disabled woman. 

* Robert Solomon argues that Singer refuses to speak in languages beyond that of a limited logic and reason that denies human compassion. 

There are many other critics who condemn Singer's perceived dismissal of human dignity. What exactly are you looking for?
