What it means to be human? Can liberty be determined or defined? Let us put it in much dramatic way: can liberty be known? Is there any couple of concepts, which human history until now has been able to produce, the definition of which defines at the same time the other concept? If we define what it means to be human we define at the same time almost immediately also the concept of liberty and if we define what liberty is we define at the same time what it means to be human. What does it mean to be human? Why are there humans? Is the sense of the fact that there are humans is determined prior to their existence or have humans themselves have to determine what the sense of their existence is? If the sense of the existence of humans is determined prior to their existence how can we know what it is? Where have we to look for if we want to know what has been determined prior to the existence of humans? But if humans themselves have to determine what it means to be human, what are the criteria which may be helpful? Has this decision to be made individually or collectively by society as a whole? Perhaps it is an individual and at the same time a collective decision.

What is liberty? If we think about liberty in relation to rights, there arises the question whether liberty means merely rights? Or rather does liberty not necessarily include at the same responsibilities? If we take liberty in this sense to include rights and responsibilities at the same time would this not contradict the very essence of the concept of liberty? What is then liberty? Is it liberty when it is said that everyone should be allowed to do what he/she wants to for example? Almost everyone ascribes to this claim. And on the other hand what does it mean to be able to say that I have lived? What does it mean to fulfil oneself?"
