The Dictionary of Irish Philosophers spans 15 centuries of Irish thought, from the Irish Augustine in the 7th century, to Iris Murdoch and J.O. Wisdom in the 20th. Over 180 individuals who have contributed to Irish philosophical thought are chronicled. Entries profile major philosophers and other thinkers, including John Scottus Eriugena, Francis Hutcheson, George Berkeley, Iris Murdoch, Robert Boyle, William Thompson, Edmund Burke and John Tyndall. The dictionary ranges beyond the major figures, however, including those whose contributions are less well known but nonetheless original and thought-provoking, e.g. Arthur Little on aesthetics, Alice Oldham on socialism, George Sigerson on evolution and T.W. Rolleston on the life-force.
