The study of language is of interest to the 

 lawyer as vieW as the clergyman, the scientist as 

 well as the teacher, and no education is com- 

 plete without it. 



Max Miiller says In this most instructive and 

 interesting book : 



" Try to reckon without numbers, whether spoken, 

 written, or otherwise marked, and if you succeed in that, 

 I shall admit that it is possible to reason or reckon with- 

 out words, and that there is in us such a thing, or such 

 a power or faculty, as reason apart from words. * * * 



" People do no longer believe in witches nor in ghosts. 

 But the belief in disembodied thought will die very hard. 



*' As little as we possess a thing called hunger because 

 we are hungry, do we possess a thing called reason be- 

 cause we are rational. Why then, should we write it 

 with a Capital R, and make a goddess of Reason and 

 worship her, as she was actually worshipped in the streets 

 of Paris ? * * * "
