“Sapere Aude! Have the courage to use your own intelligence!”
Immanuel Kant (1724–1804) German philosopher
What is Enlightenment? (1784)
Variant: Have the courage to use your own reason- That is the motto of enlightenment.
Source: Groundwork of the Metaphysics of Morals
Context: Enlightenment is man’s leaving his self-caused immaturity. Immaturity is the incapacity to use one's intelligence without the guidance of another. Such immaturity is self-caused if it is not caused by lack of intelligence, but by lack of determination and courage to use one's intelligence without being guided by another. Sapere Aude! Have the courage to use your own intelligence! is therefore the motto of the enlightenment.
Khalil Gibran (1883–1931) Lebanese artist, poet, and writer
The Forerunner (1920)
Context: You are your own forerunner, and the towers you have builded are but the foundation of your giant-self. And that self too shall be a foundation.
And I too am my own forerunner, for the long shadow stretching before me at sunrise shall gather under my feet at the noon hour. Yet another sunrise shall lay another shadow before me, and that also shall be gathered at another noon.
Always have we been our own forerunners, and always shall we be. And all that we have gathered and shall gather shall be but seeds for fields yet unploughed. We are the fields and the ploughmen, the gatherers and the gathered.
