L. S. Vygotsky's cultural-historical psychology is considered to be classic-organic psychology. Its organicity is a result of lifting the opposition between objective and subjective (in psyche, consciousness and life). The author shows that affective-sensorial formations constructing culture (ideal forms) are objective as well as subjective. The same formations constructing individual psyche and consciousness (real forms) are subjective as well as objective. The correlations between ideal and real forms are described as mutual outcome of them. The processes of outcome are due to mediators: Another (I - You correlation), sign, word, symbol, myth. The mediators as well as real and ideal forms possess subjective-objective properties (outer and inner forms). That is why they can be mediating in the acts of mutual outcomes of ideal and real forms. The organicity of Vygotsky's cultural-historical psychology is due to primary compatibility of complimentarity, congeniality of ideal, real and mediating forms, resulting in a new ontology of psychological science. When cultural-historical psychology reveals the acts of outcome mechanisms, it would become event-historical one.
