Is the Biosphere Priceless?
The German nineteenth century philosopher, Immanuel Kant, wrote that there are two kinds of things: things that have a price and those that have a dignity. For Kant, only human beings have a dignity because they alone have autonomy. I would like to suggest that we should add to Kant’s list of those things that have a dignity the biosphere in which we live, or to say it in other words, the biosphere is priceless.
