Some of the greatest modern philosophers held racist views. John Locke (1632-1704), David Hume (1711-76), Immanuel Kant (1724-1804), G W F Hegel (1770-1831) and many others believed that Black and Indigenous peoples the world over were savage, inferior and in need of correction by European enlightenment. No serious philosopher today defends these explicitly racist views but, with good reason, they continue to study the writings of these authors. However what impact does it have on society today?
