Answer: The philosopher that wrote "Sapere aude" was Immanuel Kant.
Explanation: "Sapere aude", which is the motto of the Enlightenment, is a Latin phrase used to mean "Dare to know". Although it was first used by the poet Horace in 20 BCE, Immanuel Kant, a German philosopher who supported trascendental idealism, was the first to use it to refer to the Enlightenment. Kant introduced the phrase "sapere aude" in his essay “Answering the Question: What Is Enlightenment?” written in 1784 to emphasize the importance of reason when dealing with human affairs.
