Abstract
In principle, a proposition is symbolized as words and images in the system of subject-predicate relation. Whitehead propositional theory asks what is the presentational immediacy and how the foundation of consciousness is established by this symbolism.
The presentational immediacy is based on the causal efficacy, that is associated with it in a subjective form. There is a role of symbolic reference to be involved in the process and to create the productive image. According to the flow led by the causal efficacy, the presentational immediacy is formed as image. In the process of symbolism, the pure potentiality (the eternal objects contained therein) is transformed into the propositions. A public-private alternative takes place and an idea of responsibility arises. It is imagination that is operating strongly behind it.
The pure potentiality by itself never falls into time, and as such is 'pure'. If it become realized, converted to impure, it turns into the real potentiality and finally into the actual entities. From the point of view of the present, the pure potentiality can not be positioned at all and stays the unpredictable. The pure potentials do not exist in the present time, and thus the eternal objects are waiting in the future. Future is an unknown potential, and that is the horizon which the concept of pure potentiality looks forward to.
