The courage To question and to inquire by Arthur Schopenhauer

It is the courage to make a clean breast of it in the face of every question that makes the philosopher.
He must be like Sophocles' Oedipus, who, seeking enlightenment concerning his terrible fate, pursues his indefatigable inquiry even though he divines that appalling horror awaits him in the answer.
But most of us carry with us the Jocasta in our hearts, who begs Oedipus, for God's sake, not to inquire further.
Arthur Schopenhauer,Letter to Johann Wolfgang von Goethe
