 When discussing the notion of what makes life good for the individual living that life, it is preferable to use the term ‘well-being’ instead of ‘happiness’. For we want at least to allow conceptual space for the possibility that, for example, the life of a plant may be ‘good for’ that plant. And speaking of the happiness of a plant would be stretching language too far. (An alternative here might be ‘flourishing’, though this might be taken to bias the analysis of human well-being in the direction of some kind of natural teleology.) In that respect, the Greek word commonly translated ‘happiness’ (eudaimonia) might be thought to be superior. But, in fact, eudaimonia seems to have been restricted not only to conscious beings, but to human beings: non-human animals cannot be eudaimon. This is because eudaimonia suggests that the gods, or fortune, have favoured one, and the idea that the gods could care about non-humans would not have occurred to most Greeks.
