MAN'S PLACE IN NATURE 

 ADVERTISEMENT TO THE READER 



THE greater part- of the substance of the fol- 

 lowing Essays has already been published in the 

 form of Oral Discourses, addressed to widely 

 different audiences during the past three years. 



Upon the subject of the second Essay, I delivered 

 six Lectures to the Working Men in 1860, and 

 two, to the members of the Philosophical Institu- 

 tion of Edinburgh in 1862. The readiness with 

 which my audience followed my arguments, on 

 these occasions, encourages me to hope that I 

 have not committed the error, into which working 

 men of science so readily fall, of obscuring my 

 meaning by unnecessary technicalities : while, the 

 length of the period during which the subject, 

 under its various aspects has been present to my 

 mind, may suffice to satisfy the Reader that, my 

 conclusions, be they right or be they wrong, have 

 not been formed hastily or enunciated crudely.
