“[on slavery] It may one day come to be recognized that the number of the legs, the villosity of the skin, or the termination of the os sacrum are reasons equally insufficient for abandoning a sensitive being to the same fate.” Jeremy Bentham
In order to judge whether or not other animals do have inherent moral worth, and so by extension have inherent rights that are untouchable, we need to heavily consider our own psychological shortcomings and our moral double standards that we all apply throughout our daily lives. For many of us they include the erroneous belief that we have the right to ignore other sentient, sensitive creatures’ inherent moral worth and qualification to rights. Regarding the importance of human psychology in assessing the fundamental issue of animal rights, we need to know what self-limiting flaws we have inherent in our psychological and evolutionary makeup that cloud our ability to think clearly and judge confidently. After all, our position is one of absolute power; that is we are Gods to the animals – we have the power, at our very whim, to cripple any other animal’s entire existence.
