Elevating Animals
Although the idea that animals have rights goes back at least to the eighteenth century, it has only recently become something of a cause célèbre among numerous serious and well-placed intellectuals, including moral and political philosophers. Jeremy Bentham, for example, seems to have suggested legislation requiring humane treatment of animals, but he did not defend animal rights per se -- not surprisingly, since Bentham was not impressed with the more basic (Lockean) doctrine of natural rights. John Locke's idea of natural rights has had enormous influence, however, and even where it is not respected, it is often invoked as some kind of model for what it would take for something to have rights.
In recent years the doctrine of animal rights has found champions in important circles where the general doctrine of rights is itself well respected. For example, Professor Tom Regan, in his important book The Case for Animal Rights, finds the idea of natural rights intellectually congenial and extends this idea to cover higher animals. The political tradition that Regan works in appears to be Lockean, but he does not agree that human nature is distinctive enough, in relevant respects, to restrict the scope of natural rights to them alone.
Following a different tradition, namely, utilitarianism, the idea of animal liberation has emerged. This can lead to roughly the same conclusions as the natural-rights tradition, but the argument is different because for utilitarians, what is important is not that humans or other animals must have a specific sphere of dominion, but that they be well off in their lives. So long as the bulk of the relevant creatures enjoy a reasonably high living standard, the moral and political objectives for them will have been met. But if this goal is not reached, moral and political steps are required to improve on the situation. Animal liberation is such a step.
Before answering the question of whether animals have rights, I want to note that rights and liberty are certainly not the only things of moral concern to us. There are innumerable other moral issues one can raise, including about the way human beings relate to animals. In particular, there is the question of how people should treat animals. Should they be hunted even when this does not serve any vital human purpose? Should they be utilized in hurtful -- indeed, evidently agonizing -- fashion even for trivial human purposes? Should their pain and suffering be ignored in the process of being made use of for admittedly vital human purposes?
It is clear that once one has answered the question of whether animals have rights or ought to be liberated from human beings, one has by no means disposed of these other issues. I will be dealing mostly with the issues of animal rights and liberation, but I will also touch briefly on the other moral questions just raised. I will indicate why they may all be answered in the negative without it being the case that animals have rights or should be liberated -- that is, without raising any basic political issues. For example, one could address the issue, which is mainly one of ethics, as to whether animals ought to be hunted, used for sport, domesticated, etc. But these are beyond the scope of the present discussion, one that focuses primarily on matters of politics and law.
So, then, in this discussion I will argue that animals have no basic rights to life, liberty, or property. Now this is a task that needs to be approached obliquely since it is not possible to straightforwardly prove a negative proposition. That is one reason that in the criminal law it is the prosecution that must prove its case, with the defense merely needing to refute what the prosecution advances instead of having to make a case for a negative proposition, a denial. (There are metaphysical considerations that underlie this matter but we will skip these for now.)
Let’s put it this way, then: the concept of “rights” is inapplicable to considerations of how animals ought to be treated. I will argue that to think otherwise is a category mistake -- it is, to be blunt, to unjustifiably anthropomorphize animals, to treat them as if they are what they are not, namely, human beings. Rights and liberty are political concepts applicable to human beings because human beings are moral agents, in need of what philosopher Robert Nozick called “moral space,” that is, a definite sphere of moral jurisdiction where their authority to act is respected and protected so that it is they, not intruders, who govern themselves and either succeed or fail in their moral tasks.
Defenders of animal rights make their case, first and foremost, by denying any fundamental difference between persons and other animals. They claim that no fundamental faculty distinguishes humans from other animals. If, however, this is wrong, if human beings are fundamentally distinguished from other animals by virtue, say, of possessing the capacity for moral agency, for initiating conduct that can be good or bad and for taking responsibility for that initiative, then we have here a sphere of uniqueness that can give rise to concepts that will not be applicable to other than human animals.
Oddly, it is clearly admitted by most animal rights or liberation theorists that only human beings are moral agents -- for example, they never urge animals to behave morally (by, for example, standing up for their rights by leading a political revolution). No animal rights theorist proposes that animals be tried for crimes and blamed for moral wrongs. If it is true that the moral nature of human beings gives rise to the conception of basic rights and liberties, then by virtue of this alone, animal rights and liberation theorists have made a fatal admission in their case.

It is obvious that most commenters don't understand the literal meaning of the question. Humans allow (bestow the right" of other humans to own animals .... conversely, they do not allow (bestow the right) to animals to own humans.
A righ is an abstract expression of what one livimg creature allows another!
I have no problem agreeing that animals are not moral agents (meaning not that they have no morals- but have different morals to humans- ie lions have territorial laws which they all agree on- and we have no idea if they are acting instinctually or reasoning). I have no issue with the comment that animals do not behave morally towards each other - in a way people would consider to be moral. But I do think it is impossible to prove that animals have no sense of right and wrong-defined according to their own rules. This would of course mean that animals are categorically differetn between species of all sorts.
However, if humans are moral agents (which we all agree with)- then this automatically gives animals rights. Here is why- humans as moral agents hold it to be wrong to kill, enslave, or profit from the suffering of others. "Others" in law means other humans, hence the urgency of Tibor I think to demonstrate an existential difference between humans and animals. But if humans are moral agents this itself means they should not be drawing this immoral distinction. Ie it is not moral according to human law to discriminate based on intellectual capacity, appearance or even moral agency. The last point is important- human criminals who have violated the moral code are tried in just trials before they are convicted- ie they are treated with moral discretion and are preceived to have moral value- so if humans are moral agents with free will - why shouldn't they bestow basic rights to animals who also either have not moral agency or have a different one to humans?
It is a mistake to claim that, because another form of life does not or cannot hold similar or same values as human beings or to the same degree, it therefore has no values at all. It is quite clear that every form of life values one thing over another either consciously or unconsciously. If morality is simply one's set of values, I believe it quite easy to show that every form of life has a morality of sorts and is therefore a moral agent. Every life chooses among available options. There is always a basis for such choices. There is no doubt one animal form or another does not make choices the same as a human being, however, it is human arrogance to claim they must do so to qualify in a human mind for rights of their own.
Unlike those you name above, I make make no claim to a lack of fundamental difference between human beings and other forms of life. To make such a claim is an error of far broader scope than the issue of animal rights. Nevertheless, in the face of fundamental differences, we ought not put our very human expectations regarding rights onto species that have no obligation whatsoever to meet our expectations. On what basis do we require other species to meet our needs without any such obligation in the reverse? Any bases I'm aware of are decidedly humanocentric, not universal.
Whether human beings intellectually grant "rights" to other species is a matter for human beings. We debate such things to justify or suppress our own predatory instincts. I happen to believe the ability to value one's own life and the desire to go on living is hardly unique to our species. If a lion decides you may be a particularly tasty treat, your assumptions about your rights and his will be rather irrelevant. It is from that point of view any real truth in this "animal rights" debate will be found.
I agree that animals should have rights. I believe that MOST are thinking, feeling, sentient beings. Many of the species we keep as pets , mammals, reptiles, fish, and birds, definitely (in my opinion) are sentient.
It weird because I believe that reptiles are sentient, but not amphibians. The only reason that I can think for that belief is that I've never had a pet that was an amphibian. I've never formed an emotional bond with an amphibian, never spent enough time observing them to witness intelligent or emotional behavior.
I believe that invertebrates like octopus are sentient, but not clams, snails, and insects. But what about arachnids? I'm sure that spider enthusiasts would state that (at least some) spiders are sentient.
Are ALL animals sentient, from the lowliest bug to the mightiest mammal, and if not, WHERE do we draw the line, or, more importantly, HOW de we decide WHERE to draw the line?
While all of my pet have always been reptiles I wanted to share a fun fact. Most if not all reptiles are on there own from birth and of all animals I feel they have one of the strongest instinct drives for survival. Frogs (mainly most arrow frogs) after the male and female do their little dance which leads to reproduction, I say reproduction because no actual copulation occures, The male will carry tadpoles one at a time and place them in a pond or water source where the feel their child will have the best chance of survival. I feel all creatures have the right to dignity and fair treatment but am not oppossed to agriculture , hunting ,or controlled collection of species provided they are treated as such.
We include all animals and exclude plants.
So we can never again use pesticides to protect our produce.
