Abstract

There are two distinctions of orientation or of intention of a subject toward any phenomenon: "to" or "from" it, attraction or repulsion, acceptance or rejection. The +/- acceptability or pleasantness/unpleasantness of a phenomenon to a subject is the term indicating his or her +/- orientation to the perceived phenomenon. There are six components of the stream of human consciousness: contact senses, distant senses and emotions. Only four of them possess their own acceptability or pleasantness. Pleasantness of Condition of a Subject is a sum or an integral of acceptabilities of these four components. "Happiness" is the upper limit of the maximization of PCS; a subject is constantly striving to maximize PCS or to reach for happiness. An attitude of a subject to a phenomenon in the center of his or her attention is determined by the synchronous PCS. Belief/disbelief is a verbalized positive/negative attitude. Desire of a phenomenon x is a change of PCS created by the act of perceiving/imagining the phenomenon; the strength of desire is the magnitude of this change |ΔPCSx|. Desire of a phenomenon characterizes power of the PCS maximization possessed by this phenomenon. Need is a periodic desire; the desire correspondent to need is a concrete form of existence of this need. Choice is determined by comparative strength of the desirabilities of the competing elements of choice; it includes choice of the phenomena to perceive or attend. The attention of a subject toward a perceived phenomenon x is proportional to the strength of its desirability: ATTx=k|ΔPCSx| = k|DESIREx|. The distribution of attention is a function of the desirabilities of phenomena perceived at the time : ATTtotalt=k|DES1t|+k|DES2t|+…+|DESnt|. Will is an ability of the subject to influence the balance of desirabilities of elements of the subject's choice in the predetermined way. The nature of the will's effort is a self-inducement of suitable emotions through activation of memories by the concentration of the subject's attention to them.
