One of the most important features of science is that major discoveries regularly raise important ethical questions. This is especially true with research about cetaceans, because the discoveries of marine mammal scientists over the last 50 years have made it clear that whales and dolphins share traits once believed to be unique to humans: self-awareness, abstract thought, the ability to solve problems by planning ahead, understanding such linguistically sophisticated concepts as syntax, and the formation of cultural communities. The scientific evidence is so strong for the intellectual and emotional sophistication of dolphins that there simply is no question that they are ‘nonhuman persons’ who deserve respect as individuals.
Anyone who doubts this either is unfamiliar with the data or doesn’t understand the ethical significance of it. Both the killing and captivity of dolphins are ethically indefensible. This is not an emotional claim. It is based on hard science, and distinguished scientists like Lori Marino, Denise Herzing and Hal Whitehead recognize this. It’s important to recognize that facts that we now consider obvious–the Earth moves around the Sun, matter consists of invisible subatomic particles, men and women are equal, to name just three–were all considered ridiculous. Science moves forward by being open to the idea that radical ideas–in this instance, that dolphins ‘count’ as individuals and should be neither killed nor held captive–might just be true.
