"The actor is representing people: man embodies 
another.
Nowhere else is this shown to us.  

Helmuth Plessner

"To Act is harder than to know."

  
Korean buddhist saying

"If you speak in a foreign language, the voice floats isolated and naked in the air.
It's as if you do not spit out words, but birds. ...
And one of the most visible features of birds is that they are imitating the chirping of other birds. "

Yoko Tawada, The voice of a bird
