The speaker must choose a comprehensible [verständlich] expression so that speaker and hearer can understand one another. - Jürgen Habermas

Technically speaking, since our complex societies are highly susceptible to interferences and accidents,they certainly offer ideal opportunities for a prompt disruption of normal activities. These disruptions can, with minimum expense, have considerably destructive consequences. Global terrorism is extreme both in its lack of realistic goals and in its cynical exploitation of the vulnerability of complex systems.

The bourgeois public sphere may be conceived above all as the sphere of private people come together as a public; they soon claimed the public sphere regulated from above against the public authorities themselves, to engage them in a debate over the general rules governing relations in the basically privatized but publicly relevant sphere of commodity exchange and social labor.

As historical and social beings we find ourselves always already in a linguistically structured lifeworld. In the forms of communication through which we reach an understanding with one another about something in the world and about ourselves, we encounter a transcending power. Language is not a kind of private property. No one possesses exclusive rights over the common medium of the communicative practices we must intersubjectively share. No single participant can control the structure, or even the course, of processes of reaching understanding and self-understanding. How speakers and hearers make use of their communicative freedom to take yes- or no-positions is not a matter of their subjective discretion. For they are free only in virtue of the binding force of the justifiable claims they raise towards one another. The logos of language embodies the power of the intersubjective, which precedes and grounds the subjectivity of speakers.
