As I indicated in the Introduction, I will begin my tour of four select security referents at the macro level and work my way down. I will do so for four reasons. The first is to help shake off any lingering anthropocentric biases that might skew the analysis were we to work in the opposite direction. Human security, of course, naturally invites an anthropocentric treatment; culture as I shall be discussing it is also largely a human concern; and the state is a human creation. Were we to get into the habit of putting people at the centre of our analysis, we might do so too readily precisely where it would be least appropriate. The second is that ecospheric security will be the least familiar concept of the four and for that reason might risk coming across as an afterthought if I were to treat it last. Third, and relatedly, given the unfamiliar style of analysis to which I aim to subject these referents, I see advantages in giving it its first rigorous test in a context in which it is least likely to grate, hoping thereby to cultivate a degree of comfort with it once I turn to referents that we are used to analyzing in less unconventional ways. Fourth, and most importantly, I will argue that the ecosphere must take priority as a security referent, and accordingly must condition our understanding of the others. This argument would be more difficult to make were I to put various carts before the horse.
