**Abstract**

One of the biggest current issues of European society is the dramatic decrease of the natality rate in most countries. Comparing these low natality rates and the increased mortality rates, we can conclude that in a not too distant future, the European demographic fund will differ greatly from the current one. In this context, the biotechnological industry is looking for a way to extend life for as long as possible. The paper analyses the way in which the two categories – people who want to extend their life and people who want to bring it to an end – report to the transcendental relationship. The questions for which an answer is sought are: Can we, in the light of immanence, reach the truth? Which are the answers of medicine, bioethics, and theology?

**Keywords:** quality of life, immanent, transcendent, biotechnology
