The motto of enlightenment is therefore: Sapere aude! Have courage to use your ownunderstanding!
Immanuel Kant (What is Enlightenment, 1784)

Reflections on Kant
One of Immanuel Kant's most important ideas is the idea of knowing. He made a important distinction about what human beings can know and what they cant know. According to Kant science was limited to what the subjective human mind and senses could access and interpret. Our knowledge was limited to what we could perceive.
