Respectfully Quoted: A Dictionary of Quotations. 1989.
John Maynard Keynes (18831946)
The composition of this book has been for the author a long struggle of escape, and so must the reading of it be for most readers if the authors assault upon them is to be successful,a struggle of escape from habitual modes of thought and expression. The ideas which are here expressed so laboriously are extremely simple and should be obvious. The difficulty lies, not in the new ideas, but in escaping from the old ones, which ramify, for those brought up as most of us have been, into every corner of our minds.
