List of ethicists including religious or political figures recognized by those outside their tradition as having made major contributions to ideas about ethics, or raised major controversies by taking strong positions on previously unexplored problems.
All are known for an ethical work or problem, but a few are primarily authors or satirists, or known as a mediator, politician, futurist or scientist, rather than as an essayist or philosopher. Some controversial figures are included, some of whom you may see as bad examples. A few are included because their names have become synonymous with certain ethical debates, but only if they personally elaborated an ethical theory justifing their actions. Inclusion on this list is not an endorsement of any ethical point of view.
