The well-known book by Peter Singer The Liberation of Animals has not only inspired a series of texts defending the rights and interests of animals, but has also provoked a discussion about what humanity is, what meaning can our belonging to the human kind have for us, and whether Singer’ critique of the “human prejudice” is justified. The paper considers two important defenders of “human prejudice”, B. A. O. Williams and C. Diamond, who both claim the concept of human being to be a basic ethical concept. In the first part, we will present Williams’s argument that solidarity and identity with one’s species doesn’t have the structure of a blameworthy privilege similar to sexism and racism. In the second part, we will proceed to Diamond’s conception of human being that is founded in relations and responses towards the other. Just as our treatment of a human being depends on whether we see this person as our fellow, so our treatment of an animal depends on how we see it. In the last part, we will consider Diamond’s illustration of how it is possible to change our perception of an animal and thus to change our treatment of it., Kamila Pacovská., and Obsahuje poznámky a bibliografii
The concept of personal identity has recently come to play an increasingly important role in bioethical discussion concerning the beginning and end of human life. This study does not aim to represent the whole range of applications of theories of personal identity to bioethics. It focuses only on the beginning of human life, namely on the question of the moral acceptability of abortion. The author begins by describing an argument rejecting the acceptability of abortions which has been advanced by P. Lee, and it is shown that the validity of this argument depends on a certain conception of personal identity. Then the author briefly defines the psychological approach to personal identity, and he points to its weaknesses. There follows a discussion of the theory of animalism which claims that our persistence in time does not comprise any psychological factors. The conclusion of the article deals with various theories of moral status and indicates the inadequacy of functional criteria in accounting for the moral point of view. The article finishes by stating that the moral status of human beings should be founded on the concept of human dignity. If the considerations in the study have been set out correctly then they justify the following conclusion: abortions are morally unacceptable., David Černý., and Obsahuje poznámky a bibliografii
