“My difficulties lay deeper. It was more than I could believe that Jesus was the only incarnate son of God, and that only he who believed in him would have everlasting life. If God could have sons, all of us were His sons. If Jesus was like God, or God Himself, then all men were like God and could be God Himself. My reason was not ready to believe literally that Jesus by his death and by his blood redeemed the sins of the world. Metaphorically there might be some truth in it. Again, according to Christianity only human beings had souls, and not other living beings, for whom death meant complete extinction; while I held a contrary belief. I could accept Jesus as a martyr, an embodiment of sacrifice, and a divine teacher, but not as the most perfect man ever born. His death on the Cross was a great example to the world, but that there was anything like a mysterious or miraculous virtue in it my heart could not accept. The pious lives of Christians did not give me anything that the lives of men of other faiths had failed to give. I had seen in other lives just the same reformation that I had heard of among Christians. Philosophically there was nothing extraordinary in Christian principles. From the point of view of sacrifice, it seemed to me that the Hindus greatly surpassed the Christians. It was impossible for me to regard Christianity as a perfect religion or the greatest of all religions.”

Who among us would then be content with the counsels of patience and delay?”

“Ah, Hah! But you see, Baron, I know as a Mentat when you will send the executioner. You will hold back just so long as I am useful. To move sooner would be wasteful and I'm yet of much use. I know what it is you learned from that lovely Dune planet - waste not? True, Baron?

“It is the mark of an educated mind to be able to entertain a thought without accepting it.”

“Even the strongest current of water cannot add a drop to a cup which is already full. The most difficult subjects can be explained to the most slow-witted man if he has not formed any idea of them already; but the simplest thing cannot be made clear to the most intelligent man if he is firmly persuaded that he knows already, without a shadow of doubt, what is laid before him.”
