Frase de Immanuel Kant

“Sapere aude! Have the courage to use your own understanding!”

“Science is organized knowledge. Wisdom is organized life.”

“Two things fill the mind with ever new and increasing admiration and awe: the starry heavens above me and the moral law within me.”

“Act in such a way that you treat humanity, whether in your own person or in the person of any other, never merely as a means to an end, but always at the same time as an end.”

“Thoughts without content are empty, intuitions without concepts are blind.”
