The author states that the major obstacle of human beings cultivating humility is self-importance. Likewise, it is a very rare case to imagine that one may learn to cherish and value as important other human beings without also having learned to cherish other beings (both sentient and non-sentient) as well. This is remarkably similar to Kant’s defense of why we should seek to avoid kicking animals even though we have no strict moral duty to observe this behavior. Remember that Kant suggested that we are prone to emotionally dissolving the rationalizations that tell us why we shouldn’t kick other human beings when we consistently go out and kick, say, a dog. How much of Hill’s argument on this point can be said to arise out of virtue ethics and how much of this smells of Kantianism?
The ongoing argument that Hill proposes between the environmentalist and the anti-environmentalist reveals that neither side can prove the importance or the unimportance of non-sentient nature beyond its instrumental value. However, both sides can agree that the virtues individuals hold that relate to the preservation of nature are good. Just because environmentalists have yet to find an argument to prove the destruction of non-sentient nature as wrong does not justify the destruction of it.
