'' The old questions whence men come and whither they go, and \vhat 

 is the end of all their labour, still perplex philosophers and trouble the 

 simple. The anxieties of the human soul force their way even through 

 French logic into the midst of the Positive Philosophy. As long as such 

 questions are asked, so long will there be an ear for an answer." 



TIMES, October, 1809. 



" The highest intellect which issues in no certainty has completely 

 failed." THOMAS CARLYLE, 18(59. 



" Every few years some reformer or another has sprung up .... 

 and all past as well as all present experience further shows, that the 

 greater the degree of dogmatism and effrontery with which any such 

 pretender proclaims his doctrine, the greater in all probability will be 

 his success in gaining patrons amongst the credulous public." 



SIR J. Y. SIMPSON, BAET., M.D.
