From Karl Popper's Conjectures and Refutations, chapter 7, "Kant's Critique and Cosmology":
But let us see how Kant himself describes the idea of the Enlightnment :
Enlightenment is the emancipation of man from a state of self-imposed tutelage .... of incapacity to use his own intelligence without external guidance. Such a state of tutelage I call 'self-imposed' if it is due, not to lack of intelligence, but to lack of courage or determination to use one's own intelligence without the help of a leader. Sapere audé! Dare to use your own intelligence! This is the battle-cry of the Enlightenment.
Kant is saying something very personal here. It is part of his own history. Brought up in near poverty, in the narrow outlook of Pietism - a severe German version of Puritanism - his own life was a story of emancipation through knowledge. In later years he used to look back with horror to what he called 'the slavery of childhood', his period of tutelage. One might well say that the dominant theme of his whole life was the struggle for personal freedom.
 "What is the Enlightenment?" (1785); Immanuel Kant's Werke, ed., Ernst Cassirer, et al., vol iv, p. 169.
Please forward this glyph to anyone who might be interested. The Explorers Foundation Glyphery is a collection containing indications of things that have to do with the emergence of a world fit for explorers, and of a people fit to inhabit such a world. We call this the emergence of freeorder. We intend our work and the work of similar ventures to spread a conviction that such a world is the destiny of humanity, one hard fought for by a growing few over centuries. Such conviction will inspire an avalanche of events, in imagination, thought, and action that will make it so. If you share our belief that the character of the adventurer whose quests are governed by strong integrity is the heart of all possible civilizations, we would like to know you.
