"The effort of expression has a bearing not only on the form but on the thought and on the whole inner being. So long as bare simplicity of expression is not attained, the thought has not touched or even come near to true greatness. … The real way of writing is to write as we translate. When we translate a text written in some foreign language, we do not seek to add anything to it; on the contrary, we are scrupulously careful not to add anything to it. That is how we have to try to translate a text which is not written down."
