“Our weapon is our knowledge. But remember, it may be a knowledge we may not know that we possess.”

“We know that we are not dreaming, but, however unable we may be to prove it rationally, our inability proves nothing but the weakness of our reason, and not the uncertainty of all our knowledge as they maintain.”

“It is by no means certain that we advance our philosophical quest by reading Plato or Aristotle. It may increase our knowledge of history but not of the world.”

“We may know ourselves, and yet even with all the efforts we make, we do not know ourselves. We know our fellowman, and yet we do not know him, because we are not a thing, and our fellowman is not a thing. The further we reach into the depths of our being, on someone else's being, the more the goal of knowledge eludes us.”

“Knowledge grows exponentially. The more we know, the greater our ability to learn, and the faster we expand our knowledge base.”

“The end then of learning is to repair the ruins of our first parents by regaining to know God aright, and out of that knowledge to love him, to imitate him, to be like him, as we may the nearest by possessing our souls of true virtue, which being united to the heavenly grace of faith makes up the highest perfection.”
