Only he who knows how to speak can be silent. - Jean-Paul Sartre

The existent individual, as Kierkegaard defines him, is first of all he who is in an infinite relationship with himself and has an infinite interest in himself and his destiny. Secondly, the existent individual always feels himself to be in Becoming, with a task before him;

I am abandoned in the world... in the sense that I find myself suddenly alone and without help, engaged in a world for which I bear the whole responsibility without being able, no matter what I do, to tear myself away from this responsibility for an instant.

Nothingness haunts being.
