Nakana je priloga izložiti pojam tjeskobe nadahnut suvremenim filozofijskim nacrtima, osobito egzistencijalnim filozofijama kršćanskog nadahnuća Sørena Kierkegaarda i Paula Tillicha. Tjeskoba o kojoj je ovdje riječ nije »stvar« psihopatologije, već je radije egzistencijalna i ontološka u svojoj naravi. Ona stalno prijeti čovjeku kao trajno prisutna mogućnost smrti i neuspjeha. Čovjek je stoga ne može dokinuti, već ona, ispravno usvojena, u konačnici predstavlja njegovu autentičnu mogućnost samoozbiljena. Izvor je ontološke tjeskobe u čovjekovoj »konačnosti« mišljenoj kao jednoj od temeljnih »komponenti« ljudske egzistencije. Kod spomenute dvojice filozofa upravo tako mišljena tjeskoba predstavlja središnje antropologijsko učenje: ona je stanje u kojem postajemo svjesni mogućnosti vlastitog nebitka. No, svijest o nebitku implicira i pitanje o bitku, odnosno, onoj moći koje daje svemu što jest da jest i koja se u svemu što jest naslućuje. Time nam tjeskoba otvara pitanje o onoj zbilji koju tradicionalna filozofija kao i kršćanska teologija nazivaju Bogom.The intention of this contribution is to present the concept of anxiety as understood by contemporary philosophical approaches, especially those of existential philosophies of Søren Kierkegaard and Paul Tillich, inspired by Christianity. Anxiety, as discussed here, is not a matter of psychopathology, but is rather existential and ontological in its nature. It constantly threatens the human being as a permanently present possibility of death and failure. The human being can, therefore, not avoid it; instead, anxiety, properly embraced, actually presents his/her authentic possibility of self-realization. The source of ontological anxiety is to be found in the human being’s »finitude«, understood as one of the fundamental »components« of human existence. In the thought of the two aforementioned philosophers, precisely this understanding of anxiety constitutes their central anthropological teaching: it is a state in which we become aware of our own non‑being. However, the awareness of non‑being implies the question of being, i.e., that power that gives everything that is its being and that is sensed in everything that is. In this way, anxiety points to that reality that traditional philosophy and Christian theology call God
