demonstrationum") and therefore he must still have meant to 

 include the Idols of the Market-place, along with the two first, under 

 the class Innata. 



It is worthy of remark however that, in the Novum Organum 

 itself, the distinction between Adscititia and Innata disappears. And 

 the fact probably is that when he came to describe the several Idols 

 one by one, he became aware both of the logical inconsistency of 

 classing the Idola Fori among the Innata, and of the practical incon- 

 venience of classing them among the Adscititia, and therefore resolved 

 to drop the dichotomy altogether and range them in four co-ordinate 

 classes. And it is the removal of this boundary line which makes it 

 seem at first sight as if the arrangement were quite changed, whereas 

 it is in fact only inverted. According to the plan of the Partis 

 secundce Delineatio and also of the Distributio Operis, the confuta- 

 tion of the Immigrants, that is, the Redargutio Philosophiarum and 

 Redargutio Demonstrationum, was to have the precedence, and the 

 confutation of the Natives, that is, the Redargutio Rationis humance 

 natives, was to follow. As it is, he begins with the last and ends 

 with the first. And the reason of this change of plan is not difficult 

 to divine. The Redargutio Philosopkiarum, as he handles it, tra- 

 verses a wider and more various field, and rises gradually into a 

 strain of prophetic anticipation, after which the Redargutio Rationis 

 would have sounded flat.
