"Fire destroys falsehood, that is sophistry, and..." - Quote by Leonardo Da Vinci

“While you are alone you are entirely your own master and if you have one companion you are but half your own, and the less so in proportion to the indiscretion of his behavior.”

“I know very well that because I am unlettered some presumptuous people will think they have the right to criticize me, saying that I am an uncultured man. What stupid fools! Do they not know that I could reply to them as Marius did to the Roman patricians: "Do those who pride themselves on the works of other men claim to challenge mine?”

“Good men by nature, wish to know. I know that many will call this useless work... men who desire nothing but material riches and are absolutely devoid of that of wisdom, which is the food and only true riches of the mind.”

“The liar is no whit better than the thief, and if his mendacity takes the form of slander he may be worse than most thieves. It puts a premium upon knavery untruthfully to attack an honest man, or even with hysterical exaggeration to assail a bad man with untruth.”

“Children are not deceived by fairy-tales; they are often and gravely deceived by school-stories. Adults are not deceived by science-fiction ; they can be deceived by the stories in the women's magazines.”

“Is not anyone with any degree of mental honesty conscious of telling lies all day long, both in talking and writing, simply because lies will fall into artistic shape when truth will not?”

“It is the act of a bad man to deceive by falsehood.”

“Truth is like the stars; it does not appear except from behind obscurity of the night. Truth is like all beautiful things in the world; it does not disclose its desirability except to those who first feel the influence of falsehood. Truth is a deep kindness that teaches us to be content in our everyday life and share with the people the same happiness.”

“There are some disguised falsehoods so like truths, that 'twould be to judge ill not to be deceived by them.”
