Freedom interpreted as absence of restraints, as such, is a vacuous ideal. It requires reference to some setting and course of action in order to distinguish those restraints that block human effort from those, say, that support it. More broadly, this notion of freedom has little meaning and less value without some external criterion for evaluating human action and its conditions. Many thinkers have argued that the. criterion must be the absolute Truth ? truth that is unconditioned, indubitable, and imperative. (...) They have often argued that there is no freedom of error, and that the many persons who do not know such Truth are free only in obeying the few who do. This concept of freedom is often regarded as intolerable. A third possibility is to interpret freedom as a name for a range of significant alternatives for thought and action. Freedom, here, is compatible with truth interpreted in terms of the process of inquiry, rather than as substantive possession. It is a necessary condition for judging which restraints are real obstacles and which courses of action may be harmless, legitimate or good. The third meaning, especially, is illustrated with reference to the freedoms of utterance (expression) and speech (communication). (shrink)
