Note 8 — Chapter II · THE LAW OF EVOLUTION.[8]
Reading edition
The substance of this chapter is nearly identical with the first half of an essay on “Progress: its Law and Cause,” which was originally published in the Westminster Review for April 1857: only a few unimportant additions and alterations have been made. The succeeding chapter, however, in which the subject is continued, is, with the exception of a fragment embodied in it, wholly new.
