“It is only prudent never to place complete confidence in that by which we have even once been deceived.”

“...it is a mark of prudence never to place our complete trust in those who have deceived us even once.”

“Whatever I have up till now accepted as most true and assured I have gotten either from the senses or through the senses. But from time to time I have found that the senses deceive, and it is prudent never to trust completely those who have deceived us even once.”

“Once for each thing. Just once; no more. And we too, just once. And never again. But to have been this once, completely, even if only once: to have been at one with the earth, seems beyond undoing.”

“Everyone once, once only. Just once and no more. And we also once. Never again. But this having been once, although only once, to have been of the earth, seems irrevocable.”

“Of all the agonies of life, that which is most poignant and harrowing- that which for the time annihilates all reason and leaves our whole organization one lacerated, mangled heart-- is the conviction that we have been deceived where we placed all the trust of love.”
