Apart from this early adaptation of
Darwinʼs lines on the steam engine,
Ruskin
appears never again to have taken any interest in
Darwinʼs writing. He may have inherited a prejudice against
Darwin owing to opposition to his ideas by the philosopher and physician,
Thomas Brown
(
1778–1820), who was a friend and mentor of both
John James Ruskin and his
cousin,
Margaret, in their
Edinburgh days. In
1798,
Brown challenged the “materialist” foundations of evolutionary theory in
Darwinʼs
Zoonomia (
1794,
1796)—a book
that decisively turned the tide of critical opinion against
Darwin in the increasingly reactionary years
following the outbreak of the French Revolution and the rise of Napoleonic
France
(
Garfinkle, “Critical Response to the Work of Erasmus Darwin”;
Viljoen, Ruskinʼs Scottish Heritage, 120–22).
