Prejudices of the Senses
Is it not strange that our eyes always deceive us, even when we have very good sight, and that on the contrary our ears do not deceive us? Let your well-informed ear hear "You are beautiful, I love you"; it is quite certain that someone has not said "I hate you, you are ugly": but you see a smooth mirror; it is demonstrated that you are mistaken, it has a very uneven surface. You see the sun as about two feet in diameter; it is demonstrated that it is a million times bigger than the earth.
It seems that God has put truth in your ears, and error in your eyes; but study optics, and you will see that God has not deceived you, and that it is impossible for objects to appear to you otherwise than you see them in the present state of things.
