Walter Bagehot,
The English Constitution
“ The Presidential Government, by its nature, divides political life into two halves, an executive half and a legislative half; and, by so dividing it, makes neither half worth a man's having—worth his making it a continuous career—worthy to absorb, as Cabinet government absorbs, his whole soul. The statesmen from whom a nation chooses under a Presidential system are much inferior to those from whom it chooses under a Cabinet system, while the selecting apparatus is also far less discerning. ”
