The Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life - Charles Darwin 1891 - John Murray, London - Sixth Edition, with Additions and Corrections (Forty-First Thousand). ‘It is now fully recognized that the publication of Charles Darwin’s Origin of Species brought about a revolution in man’s attitude toward life and his own place in the universe. This work is rightly regarded as one of the most important books ever published, and a knowledge of it should be part of the intellectual equipment of every educated person. The book remains surprisingly modern in its assertions and is also remarkably accessible to the layman, much more so than recent treatises necessarily encumbered with technical language and professional jargon’. - Harvard University Press.

A near fine example of the sixth edition, considered the last significant edition, and to which Darwin made his final and extensive revisions, this was also the first edition in which he used the word
evolution which had commonly been associated with embryological development [though all editions concluded with the word evolved ], Darwin also added a new chapter VII, Miscellaneous Objections, to address George Jackson Mivart's detailed arguments against natural selection in On the Genesis of Species published in 1871.

In
Origin of Species Darwin ‘not only drew an entirely new picture of the workings of organic nature; he revolutionized our methods of thinking and our outlook on the natural order of things. The recognition that constant change is the order of the universe had been finally established and a vast step forward in the uniformity of nature had been taken.’ – Printing and the Mind of Man.
