Animal Rights Advocates (ARAs) are not reformers; we are not trying to improve the conditions of their exploitation-by increasing the size of their cages, say. ARAs are abolitionists; we are working for empty cages, not larger cages. Collectively, ARAs are small in number-perhaps 1% of the world's population. So you have to wonder: How did we get this way? There are at least three possible answers. - The DaVincians (after Leonardo). Some people are born that way. Awareness of animal rights is in their genes. They don't have to be convinced. They are not asking for some sort of "proof." It's just the way they are. - The Damascans (after Saul/Paul). Some have a single life-transforming experience. They are changed in the blink of an eye. - Some (Muddlers) muddle along. Nothing in the genes. No single life-transforming experience. They acquire bits and pieces of information and ideas until one day they look in a mirror and see an ARA looking back at them. Though there are different paths, they all lead to the same conclusion: the abolition of the ill-treatment of other animals because such treatment violates their rights. What does this idea ("animal rights") mean? Cannot answer this question by going to the media or by reading opinion polls. Only by thinking independently: the invitation of philosophy. Philosophy's invitation is - to think logically - to be informed - to rid ourselves of prejudice The purpose of my remarks is: to extend the invitation.
