Using covariant derivatives and the operator definitions of quantum mechanics, gauge invariant Proca and Lehnert equations are derived and the Lorenz condition is eliminated in U(1) invariant electrodynamics. It is shown that the structure of the gauge invariant Lehnert equation is the same in an O(3) invariant theory of electrodynamics.

It is traditionally believed that cerebral activation (the presence of low voltage fast electrical activity in the neocortex and rhythmical slow activity in the hippocampus) is correlated with arousal, while deactivation (the presence of large amplitude irregular slow waves or spindles in both the neocortex and the hippocampus) is correlated with sleep or coma. However, since there are many exceptions, these generalizations have only limited validity. Activated patterns occur in normal sleep (active or paradoxical sleep) and during states of anesthesia (...) and coma. Deactivated patterns occur, at times, during normal waking, or during behavior in awake animals treated with atropinic drugs. Also, the fact that patterns characteristic of sleep, arousal, and waking behavior continue in decorticate animals indicates that reticulo-cortical mechanisms are not essential for these aspects of behavior.

An adequate theory of rights ought to forbid the harming of animals to promote trivial interests of humans, as is often done in the animal-user industries. But what should the rights view say about situations in which harming some animals is necessary to prevent intolerable injustices to other animals? I develop an account of respectful treatment on which, under certain conditions, it’s justified to intentionally harm some individuals to prevent serious harm to others. This can be compatible with recognizing the (...) inherent value of the ones who are harmed. My theory has important implications for contemporary moral issues in nonhuman animal ethics, such as the development of cultured meat and animal research. (shrink)

Because spaying/neutering animals involves the harming of some animals in order to prevent harm to others, some ethicists, like David Boonin, argue that the philosophy of animal rights is committed to the view that spaying/neutering animals violates the respect principle and that Trap Neuter Release programs are thus impermissible. In response, I demonstrate that the philosophy of animal rights holds that, under certain conditions, it is justified, and sometimes even obligatory, to cause harm to some animals in order to prevent (...) greater harm to others. As I will argue, causing lesser harm to some animals in order to prevent greater harm to others, as TNR programs do, is compatible with the recognition of the inherent value of the ones who are harmed. Indeed, we can, and do, spay/neuter cats while acknowledging that they have value in their own right. (shrink)

In The Case for Animal Rights, Tom Regan argues that although all subjects-of-a-life have equal inherent value, there are often differences in the value of lives. According to Regan, lives that have the highest value are lives which have more possible sources of satisfaction. Regan claims that the highest source of satisfaction, which is available to only rational beings, is the satisfaction associated with thinking impartially about moral choices. Since rational beings can bring impartial reasons to bear on decision making, (...) Regan maintains that they have an additional possible source of satisfaction that nonrational beings do not have and, consequently, the lives of rational beings turn out to have greater value..

Higher-order thought theories maintain that consciousness involves the having of higher-order thoughts about mental states. In response to these theories of consciousness, an attempt is often made to illustrate that nonhuman animals possess said consciousness, overlooking an alarming consequence: attributing higher-order thought to nonhuman animals might entail that they should be held morally accountable for their actions. I argue that moral responsibility requires more than higher-order thought: moral agency requires a specific higher-order thought which concerns a belief about the rightness (...) or wrongness of affecting another’s mental states. This “moral thought” about the rightness or wrongness is not yet demonstrated in even the most intelligent nonhuman animals, thus we should suspend our judgments about the “rightness” or “wrongness” of their actions while further questioning the recent insistence on developing an animal morality.

De uma perspectiva comportamentalista radical, o eu é um repertório verbal complexo, que, como tal, tem uma gênese social. O reconhecimento da origem social do “eu” abre caminho para uma análise política, incluindo uma discussão do pa- pel das relações de poder na constituição do eu. Entretanto, uma concepção radicalmente social do “eu”, como a proposta pelo comportamentalismo, suscita um problema político: se o eu é integralmente produto do ambiente social, de onde viria uma eventual “vontade” de romper com esse (...) sistema? Parece que para reconhecer a possibilidade de ação política transformadora seria preciso preservar uma noção descontextualizada de “eu”. Considerando essa dificuldade, o objetivo deste artigo é propor uma interpretação política da constituição do “eu” no âmbito do comportamentalismo radical, mantendo no horizonte a possibilidade de uma ação política transformadora. Para tanto, destacamos como “eus” oprimidos são tornados submissos, mas também como de certas contingências podem emergir “eus” subversivos, que se opõem a um sistema social opressivo. Esse “eu” subversivo é caracterizado por um repertório de autoconhecimento mais amplo, que inclui a discriminação do papel das relações de poder e do controle promovido por instituições. Concluímos, com isso, que um “eu” socialmente constituído pode ser politicamente ativo. (shrink)

It is common for conservationists to refer to non-native species that have undesirable impacts on humans as “invasive”. We argue that the classification of any species as “invasive” constitutes wrongful discrimination. Moreover, we argue that its being wrong to categorize a species as invasive is perfectly compatible with it being morally permissible to kill animals—assuming that conservationists “kill equally”. It simply is not compatible with the double standard that conservationists tend to employ in their decisions about who lives and who (...) dies. (shrink)

Investigates the resolution of contradictions and ambiguous derogations in a code, by means of the imposition of partial orderings. Although formulated as a study in the logic of norms, it provided the initial ideas for work on the logic of theory (or belief) change, developed by the authors in a series of papers by the authors and Peter Gardenfors beginning in 1985.

The philosophy of animal rights is often characterized as an exclusively justice oriented approach to animal liberation that is unconcerned with, and moreover suspicious of, moral emotions, like sympathy, empathy, and compassion. I argue that the philosophy of animal rights can, and should, acknowledge that compassion plays an integral role in animal liberation discourse and theory. Because compassion motivates moral actors to relieve the serious injustices that other animals face, or, at the very least, compassion moves actors not to participate (...) in or cause these injustices, the philosophy of animal rights can and should recognize both a duty to cultivate compassion and a duty to promote compassion. Contra to feminist critiques of Regan’s justice-approach to ethics, the philosophy of animal rights is not committed to eschewing the moral emotions. (shrink)

This chapter is written for an audience that is not intimately familiar with the philosophy of animal consumption. It provides an overview of the harms that animals, the environment, and humans endure as a result of industrial animal agriculture, and it concludes with a defense of ostroveganism and a tentative defense of cultured meat.

Nevertheless, and in spite of these drawbacks, it will be clearly intimated to him that the value of philosophy is, indeed, very great, although it happens ...

A Page of this MS, which however I discovered independently, is reproduced by M. Chatelain in his Paléographie des Classiques Latins, and for an account of the codex I refer to vol. ii. p. 11 of that work. The volume consists of four parts: Juvenal, ff. 1–47; Persius, ff. 48–59; Horace, ff. 60–93; Juvenal, ff. 94–113. This last part contains Sat. i. 1–ii. 66, iii. 32–vi. 437, i.e. two intermediate leaves, the two outside double leaves of the first quire of (...) eight, of 34 lines on a page, have been lost. The quires b and c are disordered. Foil. 94v–97 contain i. 1–ii. 66, ff. 98–105, v. 98–vi. 437, ff. 106–113, iii. 32–v. 97. (shrink)

No one probably feels tempted to deny that our best authority for the text of the Tragedies is the Etruscus, E , but the authority relatively due to the interpolated tradition A is still a matter of dispute. Leo indeed professed to deny all authority to the evidence of A, even where E is manifestly corrupt. But we should be justified in doing this only if the interpolator of A had based his edition on the text of E, and the (...) text of E had suffered no corruptions subsequent to the making of the A edition. That this is so there is not the least reason to suppose. Peiper therefore was right in requiring for his apparatus criticus an account of the pure A text, though neither he nor Richter took the trouble to search out the oldest and best MSS of the A tradition out of the three hundred or more available.
