'Lay Sermons, Addresses and Reviews' by Thomas Henry Huxley is a diverse collection of essays that showcase his brilliance as a tireless champion of science education, philosopher, and popularizer. Through this collection, Huxley refutes the misconception that he was merely a defender of Darwin and demonstrates his originality as a thinker. The essays cover a range of topics, from arguing for science education in Britain to giving "science lessons" to the public on subjects such as zoology and geology. Huxley also defends Darwinian evolution against criticisms that still exist today and offers a window into his view of materialism. This well-written collection offers a fascinating insight into the mind of one of the most important scientific thinkers of the 19th century.
