The Question of Value in Environmental Ethics 1. INTRINSIC AND EXTRINSIC VALUE The most fundamental philosophical task in environmental ethics today is to argue that nature is intrinsically valuable. But what is intrinsic value vis-a-vis its opposite? The distinction between intrinsic and instrumental value is employed in ethical philosophy in other (non-environmental) contexts as well. Extrinsic or instrumental values are means to further ends; they are not ends in themselves. If the end of an instrumental value leads to a further end, that end itself turns out to be an instrumental value oriented towards another value. The chain can be very long. An example will make the concept clear. Paper money or currency, though greatly valuable, is not intrinsically valuable since it has no worth on its own. Currency without its attached value to buy something with is a useless piece of paper. So, a bank note may be instrumental to purchase a football. Now, the football is possibly not valuable in itself; it is valued for the game it can be played with. For some their favourite game may be valuable in itself, for the fulfilment and enjoyment it gives, but for others a game may not be valuable in itself, but is valuable for something bigger, say, health. Now, healthy life for some may not be valuable in itself but for the happiness and general wellbeing it brings. And so on... goes the chain of instrumental values leading to something more intrinsic, something that is valuable in itself. Hence, an intrinsic value is not dependent on another end for its value; it is selfsufficient, self-reliant. It is justified on its own regardless of whether it is also useful as means to other ends. A wild plant may have instrumental value because it provides the ingredients for some medicine or as an aesthetic object for human observers. But if the plant also has some value in itself independently of its prospects for furthering some other ends such as human health, or the pleasure from aesthetic experience, then the plant also has intrinsic value. Because the intrinsically valuable is that which is good as an end in itself, it is commonly agreed that something’s possession of intrinsic value generates a prima facie direct moral duty on the part of moral agents (human beings) to protect it or at least refrain from damaging it. Hence, in environmental ethics, the notion of intrinsic value is of utmost importance. 2. THE ENLIGHTENMENT VIEW: ONLY HUMANS HAVE INTRINSIC VALUE Enlightenment is the historical stage of Europe’s passage from the blind faith and unreason of the middle ages (dark ages) to the age of reason, light, questioning and science. According to the late Enlightenment philosopher, Immanuel Kant (we have mentioned it before), ‘Enlightenment’ means independence of thought, ability to think and decide on one’s own without dependence on authorities like religion and the state. Now, Kant argued that only human beings have intrinsic value and only they should be within the parameters of morality. That is, the question of moral behaviour arises only
