“There are mysteries which men can only guess at, which age by age they may solve only in part.”

“My only doubt was as to whether any dream could be more terrible than the unnatural, horrible net of gloom and mystery which seemed closing around me.”

“Our toil must be in silence, and our efforts all in secret; for this enlightened age, when men believe not even what they see, the doubting of wise men would be his greatest strength.”

“You English have a saying which is close to my heart, for its spirit is that which rules our boyars: "Welcome the coming, speed the parting guest.”

“Do you not think that there are things which you cannot understand, and yet which are; that some people see things that others cannot? But there are things old and new which must not be contemplate by men´s eyes, because they know -or think they know- some things which other men have told them. Ah, it is the fault of our science that it wants to explain all; and if it explain not, then it says there is nothing to explain.”

“Oh, my dear, if you only knew how strange is the matter regarding which I am here, it is you who would laugh. I have learned not to think little of any one's belief, no matter how strange it may be. I have tried to keep an open mind, and it is not the ordinary things of life that could close it, but the strange things, the extraordinary things, the things that make one doubt if they be mad or sane.”

“But we are pledged to set the world free. Our toil must be in silence, and our efforts all in secret. For in this enlightened age, when men believe not even what they see, the doubting of wise men would be his greatest strength. It would be at once his sheath and his armor, and his weapons to destroy us, his enemies, who are willing to peril even our own souls for the safety of one we love. For the good of mankind, and for the honor and glory of God.”
