Today I came to reflect on something that Sartre says.

He says that if we make the aristotelian argument that all things are 
defined by their characteristics. And if man is mostly defined by his 
behaviour, then each man is existentially bound to others behaviour. From 
that, he argues, that man is ultimately responsible for his choices with 
regards to all of humanity, as his choice of behaviour outline what it is 
to be human.

This is not a liberal philosophy.

But there is, ofcourse, another assumption in this. It is the ontological 
commitment that man is. Sartre does commit to the object of man.

Now, on to something else. If you reflect on the declaration of human 
rights, is is clear that it makes the same ontological commitment. The 
human rights declares what you are entitled to as a human being, but more 
importantly it assumes human being to be a meaningful category, and it 
makes the identification that all men belong to this category.

Because of this, a society based on human rights cannot be liberal in an 
abstract sense. This is the contradictory nature of liberal democracies, 
that they are not ultimately about freedom, but about promoting a certain 
lifestyle and values.
