The article introduces the concept of operational truth, which does not claim to reflect reality but instead prompts a corresponding experience or way of thinking, serving as a stimulus or impetus for a particular vision. The clearest example is the instruction for no-thinking in meditation, where thoughtlessness indicates depth of concentration rather than renunciation of thinking. Operational truth is compared with pragmatic and instrumental truth theories and traditional operationalism.
The philosophy of dialogue, explored through the works of Martin Buber, Ferdinand Ebner, Franz Rosenzweig, and Eugen Rosenstock-Huessy, redefines language as an existential, communicative act that overcomes the loneliness of consciousness and opens new philosophical meanings. It opposes monological thinking, arguing that true depth of consciousness arises only in communication, which shapes human freedom, identity, and the meaning of life. Language becomes an anthropological category tied to subjective time, especially the present moment of "here and now" communication, while past and future are linked to different forms of speech. This transforms the concept of the individual and the foundations of anthropology.
