Herbert Spencer

A fundamental error pervading the thinking of nearly all parties, political and social, is that evils admit of immediate and radical remedies. ‘If you will but do this, the mischief will be prevented.’ ‘Adopt my plan and the suffering will disappear.’ ‘The corruption will unquestionably be cured by enforcing this measure.’ Everywhere one meets with beliefs, expressed or implied, of these kinds. They are all ill-​founded. It is possible to remove causes which intensify the evils; it is possible to change the evils from one form into another; and it is possible, and very common, to exacerbate the evils by the efforts made to prevent them; but anything like immediate cure is impossible.
