This text explores the nature of concepts such as truth and human rights, which cannot be perceived through the senses or physically grasped. The author warns against the common misconception that these entities are merely subjective fabrications or mental inventions simply because they lack a material form. Such an approach is identified as a prejudiced understanding of reality that prevents any genuine investigation into phenomena excluded by this narrow definition. The work emphasizes that the non-material nature of these values does not diminish their status as realities. If a researcher reflexively excludes non-sensory entities from the realm of the "real," they block their own path to understanding their true significance and impact on human existence. The reflection calls for overcoming dogmatic materialism and remaining open to truth as a metaphysical yet real dimension of the world. This methodological appeal is crucial for any serious philosophical or legal analysis of fundamental human values that transcend empirical experience.
