Free as a Bird?
We often use visual representations and metaphors involving animals to represent human freedom. Consider, for instance, “It’s time to spread to your wings”, “I couldn’t persuade her to do otherwise. It was like trying to hold back wild horses”, “She’s a bit of a lone wolf”, “A lion does not concern himself with the opinion of sheep”. Conversely, the caged animal often serves as a symbol of human suffering, imprisonment, and oppression.
Yet many philosophers do not think animals have a genuine interest in freedom. For these thinkers, freedom only matters for nonhuman animals insofar as it contributes to their welfare. On such a view, there is nothing wrong with enslaving – if it can be called that – a nonhuman animal provided we can keep them healthy and happy. By contrast, enslaving a human is never acceptable, no matter how happy you can make them. This is because humans (and perhaps a few of the so-called higher animals) have a unique noninstrumental interest in freedom, which means that freedom matters for its own sake and not for the sake of anything else.
