  These personalized experiences of limitation should not be discounted. The philosophy of disability suggests that we need to recalibrate our sensibilities to honor the evidence of other people's senses, especially of their own embodiment. People's testimony about their own limitations and incapacities deserves respect even if uncorroborated by biological confirmation. Such experienced limitations may place the individual at activity-impeding, pain-inducing or life-threatening risk. As Davis argues eloquently, we improperly burden people whose limitations we cannot directly see, and aren't sufficiently knowledgeable to appreciate, by constantly challenging them to prove their disabilities.
