Subjectivity and Eternal Motion
In subjective knowing, thoughts appear as objects, just as rocks, trees, birds and other human beings appear as objects in the field of vision of a subjective knower. The physical body of the knower also appears as an object. The differentiation of two distinct fields of knowledge (inner and outer) and use of the terms extroversion and introversion is based on identification of the knower with the physical body.
This is a natural identification, common to human experience, but it is not inevitable; the knower can also be self-identified, and detached from the physical body.
Either way, individual consciousness includes both those contents typically labeled subjective (thought, emotions, feelings, desires, etc.) and those typically labeled objective (objects in the world such as trees and buildings). Existentially speaking, few question whether the buildings and trees they see are also seen by others; controversy erupts only when more subtle issues are at stake.
The personal subjectivity, at home in the body, normally accepts the division of "inner" and "outer" in accordance with the existential logic of social relations.
Alive only temporarily in a world of continuous change, an existing individual necessarily relies on tentative interpretations of events. Tentative though they may be, these interpretations are used to alter the course of life individually, socially and universally, for better or worse. Error produces effects as surely as right knowledge, but much can be learned precisely from errors when they are noted and understood.
From one angle, the world and everything experienced is MOTION seen from a point of centralized consciousness, the spiritual ego. All known forms are transient, and human life appears as a series of changes from birth to death, "inner" changes in consciousness included. Even the "identity" is a variable factor, and the mystery of "identification" remains to be explored.
MOTION in the human world boils down to will in action. Even a field observer needs a will to climb the hill, before looking down.
Our lives are a story that remains unfinished, a work in progress.
