bytí

Bytí is the Czech word for existence or being, used in philosophy to denote the state or fact of something existing. It is the nominalized form of býti (to be) and commonly contrasts with nebytí (non-being). In ordinary Czech, bytí can refer to existence in a general sense; in philosophical contexts it designates the ontological question of what it means for something to be.

In ontology and metaphysics, bytí is the central subject of inquiry. Philosophers ask about the nature of being, the difference between individual beings (entities) and being as such, and the conditions that make existence possible. In translations of European philosophy, the term serves as the Czech counterpart to the German Sein and the broader notion of being in metaphysical discourse.

Historical and contemporary usage in Czech philosophy treats bytí as a core theme across phenomenology, existentialism, and moral philosophy. In the 20th century, Czech thinkers such as Jan Patočka and Ladislav Hejdánek discussed bytí in relation to human existence, finitude, responsibility, and meaning. These discussions often contrast everyday existence with more authentic or reflective modes of being, linking the concept to questions of culture, spirituality, and ethics.
