Choice is at the heart of ethics, but our choices are never entirely free. Human choice is fettered by history, by context, by biology, by expected consequences and by imagination. Every choice has a history, and a price. In world politics, the scope for choice seems particularly fettered. Historical and geographical contextualization, and projected price have meant that politics beyond state borders has traditionally been understood as an arena of necessity, not ethics. Choice may never be entirely free, but neither is it totally determined; to argue it is, as a result of biology, the unconscious, predestination or whatever would be to abolish ethics. This is not our position, or that of the contributors. We do however recognize that the fettering of ethical choice begins at birth.
