I love this quote from French mathematician and philosopher, Blaise Pascal (1623-1662).
“I have only made this letter longer because I have not had the time to make it shorter.”
(Letter 16, 1657)
To condense one’s writing down to, say, one third of its original volume is a very difficult task. There are parts that the author is very reluctant to omit. This is where a strong, yet understanding, editor proves to be invaluable.
The resultant passage of writing can become much more powerful than the original, creating greater impact on the reader.
That is all I have to say on the matter!
