The paper deals with phenomenological idea of a passive synthesis. In this context, association is considered as the main form of passive synthesizing of experience subjects. Proceeding on this assumption, the author raises a problem of things identity, i. e., the notion of “thing” is presented as the rule or the idea. Basing on the investigation of the passive synthesis, the author applies to the kind of constituted in the consciousness experience complexes or systems of subjectivenesses which are distributed on the affection relief and which undergo retentional-protentional modifications. These complexes of sujectivenesses, which are flowing in time, are called the world of our experience.
