some of the most prominent thinkers of the Victorian age (three of whom would become presidents of the Royal Society). Members included physicist-philosopher John Tyndall and Darwin's cousin, the banker and biologist Sir John Lubbock. There were also some quite significant satellites such as liberal clergyman Arthur Stanley, the Dean of Westminster; and guests such as Charles Darwin and Hermann von Helmholtz were entertained from time to time. Through such associations, Spencer had a strong presence in the heart of the scientific community and was able to secure an influential audience for his views. Despite his growing wealth and fame he never owned a house of his own. Later life The last decades of Spencer's life were characterised by growing disillusionment and loneliness. He never married, and after 1855 was a life-long hypochondriac who complained endlessly of pains and maladies that no physician could diagnose at that time.

Spencer's political views from this period were expressed in what has become his most famous work, The Man Versus the State. The exception to Spencer's growing conservatism was that he remained throughout his life an ardent opponent of
