Abstract
The main Theme of this paper is “subjectivity” as the fundamental form of every subject. The subjectivity is considered in this project as the capacity of the corporal subject to orient himself spatiotemporally and to produce his relation to world. The subject means the spatiotemporal realization (i.e. actus) of the subjectivity. This capacity is divided into its three sorts as the three aspects of the subjectivity: 1. the perceiving or conscious subjectivity, 2. the egocentric or self-conscious subjectivity and 3. the inter-subjecting subjectivity. By analogy with the three aspects of the subjectivity we can find three types of world: 1. the objective, 2. the subjective and 3. the inter-subjective world. The subjects can develop by virtue of the subjectivity as his essential capacity all of the sciences, determine their will by autonomy and try to communicate and to live together with other sorts of subjects. Everything that may and should be regarded as a subject entails the subjectivity as his essence. It does not matter if the subject is human being, animal, robot, cyborg, angel, God and so on.
