Free spirits? The academic on the aeroplane
指出学术流动性并非完全自愿，而是受制于结构性和制度性约束，国际会议所推崇的“可见性”要求学者脱离本地责任，这排除了需要身体在场的人，并可能损害学术知识的内容与价值。
Like business executives and politicians, academics form part of the super-mobile population of the global north. Their freedom to travel, which entails a freedom from certain local obligations, is not always voluntary but part and parcel of professional expectations and is subject to peer and managerial evaluation. In this article, we argue that there are a lot of structural and institutional constraints built into academic mobility. The original notion of intellectual detachment and academic freedom has developed into a demand for social and moral detachment by the ever-growing circuit of international ‘visibility’ as celebrated at international conferences. It excludes all those whose attachment to persons or causes requires bodily presence, and such an exclusion transforms the contents and values of academic knowledge – not for the better, we believe.
