Our words stand, become responsible for more than we intended, and this is verbal privilege.
Adrienne Rich in American Time

Pre and Post Scriptum:
People acquainted with my articles may find that some ideas and motifs keep appearing in them. I don’t remember who exactly said that each writer has only one idea which he keeps expressing in different ways. There is much truth in it. During my teaching days I always asked my students to start their papers with a question and end with a new question that emerged from their answer. In a similar way, each time I finish an article I’m left with an urge to expand some themes by looking at them from a different angle.The fact that unlike an item in an encyclopedia, this is an article that is supposed to stand on its own legs necessitates sometimes such repetitions. I pray that also my readers will find it necessary and wouldn’t get bored with it.
