" The doctrine of idols bears the same relation to the interpretation of nature as that of 

 sophisms does to common logic. It is the peculiar and perpetual error of the human under- 

 standing to be more moved and excited by affirmations than by negations; whereas it ought 

 duly and regularly to be impartial ; nay, in establishing any true axiom the negative instance 

 is the most powerful." FRANCIS BACON.
