This text discusses dialogue as a fundamental social and moral invention that transcends the boundaries of ordinary communication and mere objective thinking. The author builds on the historical distinction between 'beings' and 'objects', noting that the focus on objective reality, characteristic of ancient Greek thought, often obscured deeper interpersonal relationships. Dialogue is not understood here as a mere exchange of information or feelings, but as a creative process aimed at something that the partners bring together, yet which originally belonged to neither of them. It is a project focused on searching for and realizing a truth or meaning that stands 'between' the participants as a challenge or an assigned task. This invention of 'non-objectivity' allows people to build a new quality of coexistence through the collective discovery and manifestation of what was previously only sensed. Dialogue is thus an active act of creating and recognizing reality in its non-objectified form.
