“Normally leaving one's country is a grave step: it involves leaving the society and culture in which we have been raised,, the society and culture whose language we use in speech and thought to express and understand ourselves, our aims, goals and values; the society and culture, customs, and conventions we depend on to find our place in the social world. In large part, we affirm our society and culture, and have an intimate and inexpressible knowledge of it, even though much of it we may question, if not reject. The government’s authority cannot, then be freely accepted in the sense that the bonds of society and culture, of history and social place of origin, begin so early to shape our life and are normally so strong that the right of emigration does not suffice to make accepting its authority free, politically speaking, in the way that liberty of conscience suffices to make accepting ecclesiastical authority free.”
