Spencer, Herbert (1820–1903) British <strong>Evolution</strong>ary philosopher<br />
Herbert Spencer popularized evolutionary ideas in<br />
England and the United States. His vision <strong>of</strong> evolution was<br />
vague and, because it incorporated a Lamarckian mechanism<br />
(see Lamarckism), wrong, but it was, for a long time, more<br />
popular than Darwin’s evolutionary theory (see Darwin,<br />
Charles; origin <strong>of</strong> species [book]). Spencer was lecturing<br />
about evolutionary ideas before Darwin published the Origin<br />
<strong>of</strong> Species, and Darwin derived part <strong>of</strong> his theory—if only a<br />
single phrase—from Spencer.<br />
Born April 27, 1820, Spencer grew up in an intellectual<br />
environment (son <strong>of</strong> a schoolmaster) and spent his life<br />
writing a great outpouring <strong>of</strong> philosophical works. <strong>Evolution</strong><br />
was at the core <strong>of</strong> all <strong>of</strong> his works. He proclaimed<br />
that the evolutionary history <strong>of</strong> all things produced greater<br />
complexity and greater interdependence. Even before Darwin<br />
published the Origin <strong>of</strong> Species, Spencer wrote about<br />
the “survival <strong>of</strong> the fittest,” the phrase that Darwin later<br />
adopted to describe natural selection. Spencer had come<br />
close to the idea <strong>of</strong> natural selection, but he included it in<br />
a Lamarckian framework—that the efforts <strong>of</strong> organisms,<br />
including humans, could produce new characteristics that<br />
could be incorporated into their biological framework and<br />
passed down to future generations. Spencer was not the<br />
careful scientist that Darwin was; his scientific examples<br />
were few and vague. Since progress resulted from effort,<br />
then rich people were rich because they had superior abilities,<br />
and the poor were poor because they were lazy, or<br />
incompetent, or both, according to Spencer’s view. Spencer<br />
wrote in 1851:<br />
Blind to the fact that under the natural order <strong>of</strong><br />
things, society is constantly excreting its unhealthy,<br />
imbecile, slow, vacillating, faithless members, these<br />
unthinking, though well-meaning men advocate<br />
an interference which not only stops the purifying<br />
process but even increases the vitiation—absolutely<br />
encourages the multiplication <strong>of</strong> the reckless and<br />
incompetent by <strong>of</strong>fering them an unfailing provision,<br />
and discourages the multiplication <strong>of</strong> the competent<br />
and provident by heightening the prospective<br />
difficulty <strong>of</strong> maintaining a family.<br />
Spencer’s evolution proceeded by effort, while Darwin’s<br />
seemed to be founded upon luck. When Spencer visited<br />
America in 1882, the year Darwin died, he was immensely<br />
popular in this nation <strong>of</strong> newfound wealth resulting from<br />
the efforts <strong>of</strong> independent people exploiting a huge wilderness<br />
<strong>of</strong> resources they had recently expropriated from the<br />
Native Americans. When religious leaders such as Henry<br />
Ward Beecher embraced evolution within their theology, it<br />
was Spencer’s version, not Darwin’s. Spencer’s views encouraged<br />
the growth <strong>of</strong> social Darwinism and eugenics that<br />
were used as justification <strong>of</strong> the oppression <strong>of</strong> minorities
