“No man was ever so much deceived by another as by himself.”
“Men are so simple of mind, and so much dominated by their immediate needs, that a deceitful man will always find plenty who are ready to be deceived.”
“The most common sort of lie is that by which a man deceives himself: the deception of others is a relatively rare offense.”
“No man is hindered by another; he is only hindered by himself. No man suffers because of another; he suffers only because of himself.”
“…he who seeks to deceive will always find someone who will allow himself to be deceived.”
“We are going to the moon that is not very far. Man has so much farther to go within himself.”
