Should a pitbull be sacrified after it had slaughtered a child in the house where both lived? The author tells us that there is always a scandal, in England, everytime it comes about to media the liquidation of a dog for whatever reason. And, of course this extends to other animals. There are millions of animals being slaughtered, round the clock, for our nourrishment, as well as other human beings, at the end of a causal chain where a human purpose or conscious neglect may be identified. This book is written by a Bristol specialist who fostered an Anthropozooic Institute to care about the conviviality among Human and dogs. The book may easily be inserted in a market cluster where dog trainers compete among themselves to improve (and also certify) that conviviality. The competition erupts in the media, comes back to books, slides into Law and involves Science. Where does Ethics have a say? Everywhere, everytime. One thing is certain: the market cluster tends to be regulated as the rest of the markets, but definitely depends on some kind of power institutionalization which defines the enclusterd market.The market is no human condition, but a cultural and civilizational choice. It didn't always exist, it won't exist forever. Nevertheless, since we found our base in a Civilization, what is sick in it, and what symptoms emerge here, in this fever surge? Animal Rights campaigns are normally based in an analogical reasoning, which surpasses the dignity of one sole species, and extends it to an universe of sentient beings (sometimes even going beyond the partition into «species») and thereon, it works in terms of general Welfare, as did Jeremy Bentham. This path is contemporary of the levelling of criteria concerning minorities' statutes, where some relevant characteristics are enhanced in order to institutionalize a new set, or universe, where the injuctions are at hand of any sovereign citizen. It is a path generally taken by what some mirror as «Left» (but not only so, due to the intrinsic vagueness of the concept), it resorts to some extra-civilizational elements, notably religious ones, and follows the rules of the political market. One of the «Market» virtues dwells in the provision of information, normally in the reverse sense of its processing. It answers a human need, it is a human achievement but, as it happens with many species, Human kind is still in the middle of a huge vital experiment, of which inception and aims, doesn't master very well. The author gives us notice of very fragmentary and isolated data about registered dangers involving pittbulls, as well as recent efforts for a specific legislation on this race. He's very optimistic about the future of conviviality between Man and dog but his optimism sounds too simplistic and marketing, taking into account all his premisses. Mankind has only managed to domesticate about 20 species, the studies on animal conscience and mental faculties are still very much un-holistic and raise a lot of still unanswered questions, in a field where science is young. At a certain point, in a recent debate, some said that the life of a dog (or «my dog») would be worthier than the one of Hitler or the one of Breivick, the terrorist. They did it, replying to some who pondered that the dog should be liquidated because any human life, the most repulsive it might be, would always be worthier than the one of a dog. Of course this all should be inserted in different strategies, or policies, in the market-place of ideas.The face-valued emotions have a provocation element, to catch by surprise the indifferents and get a stage. But the sudden eruption of the debate may set a very frightening scene. Hitler himself was a vegetarian, he certainly cherished more the life of his dog than the one of many of his kin, or enemies. In the USSR (but not only so), there have been carried out many experiments with human beings and Nature in general, to prove theories such as the one of Lyssenko, which was a forgery. If the modern western society (and not only it) stands, in practice, for a field of social, political, and moral experiments, where what is true depends very much on human mentality trends, should it be there other criteria than the one of trial and error? Is it really there an innate right of self-defense when both the concepts of «self» and defense have been eroded in such a way that Sodoma and Gomorrah are just an oppressive dam, adjourning the flow of a major flood, as the narrative in the Bible implies?
