D'ALEMBERT. 437 



But the Fancy is as much a subject of intellectual science 

 as the Reason. Moreover the moral qualities belong to 

 the understanding. Under Logic he brings hieroglyphics 

 and heraldry ('La Science du Blason'), and also rhetoric, 

 including the art of versification ; but poetry belongs to 

 the third great division, Imagination, though oratory is 

 ranged under the second, with Logic. 



Thus of this celebrated classification and the famous 

 genealogical tree applied to it, the object of so much

 judge by its fruits, and they are of but mean value. It 

 shares the same blame, however, with the division of 

 Bacon, the root and seed from which it springs. We 

 find that great master of logic classifying the mechanical 

 arts and history together; nay, in his threefold division 

 of the sciences, according as the Deity, man, or external 

 nature are their objects, he classes intellectual and moral 

 philosophy with anatomy and medicine, optics and 

 acoustics with ethics, the chemical qualities of human 

 bones and blood with human philosophy, that of animal 

 bones and blood with natural philosophy. So D'Alern- 

 bert not lagging behind his master in paradox affirms 

 that imagination has the greatest share in metaphysics 

 and geometry of all the sciences connected with reason.

 suggestions, is perfectly true. That it is written in a 

 plain, perspicuous style, well suited to a didactic work, 

 is also certian. But that the impression which it pro- 

 duced was owing much more to its large scope, to the 

 amplitude of its range, than to the soundness of its doc-
