This volume presents a selection of new articles examining the state of Irish philosophy during the lifetime of Ireland's most famous philosopher, Bishop George Berkeley (1685–1753). The thinkers examined include Berkeley, Robert Boyle, William King, William Molyneux, Robert Molesworth, Peter Browne, Jonathan Swift, John Toland, Thomas Prior, Samuel Madden, Arthur Dobbs, Francis Hutcheson, Mary Barber, Constantia Grierson, Laetitia Pilkington, Elizabeth Sican, and John Austin. This interdisciplinary collection includes attention both to local Irish concerns and to Ireland's relation to the broader European context, and discusses philosophical reflections on topics as diverse as religion, economics, laughter, and motherhood.
