1. Albert Einstein:

   To know that what is impenetrable to us really exists, manifesting itself as the highest wisdom and the most radiant beauty, which our dull facilities can comprehend only in the most primitive forms--this knowledge, this feeling, is at the center of true religiousness. In this sense, and in this sense only, I belong to the ranks of the devoutly religious men.

2. C. S. Lewis:

   Love anything and your heart will be wrung and possibly broken. If you want to make sure of keeping it intact you must give it to no one, not even an animal. Wrap it carefully round with hobbies and little luxuries; avoid all entanglements. Lock it up safe in the casket or coffin of your selfishness. But in that casket--safe, dark, motionless, airless--it will change. It will not be broken; it will become unbreakable, impenetrable, irredeemable. To love is to be vulnerable.

3. Hugh Cumberland:

5. Blaise Pascal:

   For after all what is man in nature? A nothing in relation to infinity, all in relation to nothing, a central point between nothing and all and infinitely far from understanding either. The ends of things and their beginnings are impregnably concealed from him in an impenetrable secret. He is equally incapable of seeing the nothingness out of which he was drawn and the infinite in which he is engulfed.
