Starting out from some value theory-based considerations, the author subsequently questions the concept of being "fully adequate" ("vollwertig", literally: "full value") in light of the human condition, and in particular in its relation to persons with disabilities. In the context of biotic, human life as a fundamental value, a critical discussion ensues of the position held by P. Singer concerning person status of beings, with the degree of biotic perfection of man the focal point of discussion here. Extensive thought is given to the rank of human achievement within the social value system, and its meaning to persons with disabilities. Achievement is accepted as a value, given full awareness of its relativity. For persons with profound disablement, for very old and frail persons, an entitlement, without any counter consideration required, to recognition and valuation of their existence is posited, which includes the need to create overall conditions enabling humane dying in light of the concrete circumstances.
