Abstract
Value is a historical category, and there does not exist any 'super-historical" value. The value, as the distinctive character of historical category, needs to be studied from the historical dimension by applying historical methods. This is just like what Hans-Georg Gadamer says: the value-concept has to historically describe the philosophical dilemma by means of self-contemplation. The social history, however, is only the one-directional and one-dimensional extension of time. In accordance with the irreversibility of time, the past, present and future altogether constitutes a long and entire historical picture, which is the "background" and 'spatiality" of all human value activities. To research the value theory, it is necessary to comprehend and grasp its historical dimensions and methods from the perspective of time concretely.
