“To speak well of a base man is much the same as speaking ill of a good man.”
The Notebooks of Leonardo da Vinci (1883), XIX Philosophical Maxims. Morals. Polemics and Speculations.

“Tell no man anything, for no man listens
Yet hold thy lips ready to speak.”

Variant: Men are so simple and so much inclined to obey immediate needs that a deceiver will never lack victims for his deceptions.

§ IV
1910s, At the Feet of the Master (1911)
Context: See what gossip does. It begins with evil thought, and that in itself is a crime. For in everyone and in everything there is good; in everyone and in everything there is evil. Either of these we can strengthen by thinking of it, and in this way we can help or hinder evolution; we can do the will of the Logos or we can resist Him. If you think of the evil in another, you are doing at the same time three wicked things:
(1) You are filling your neighbourhood with evil thought instead of with good thought, and so you are adding to the sorrow of the world.
(2) If there is in that man the evil which you think, you are strengthening it and feeding it; and so you are making your brother worse instead of better. But generally the evil is not there, and you have only fancied it; and then your wicked thought tempts your brother to do wrong, for if he is not yet perfect you may make him that which you have thought him.
(3) You fill your own mind with evil thoughts instead of good; and so you hinder your own growth, and make yourself, for those who can see, an ugly and painful object instead of a beautiful and lovable one.
Not content with having done all this harm to himself and to his victim, the gossip tries with all his might to make other men partners in his crime. Eagerly he tells his wicked tale to them, hoping that they will believe it; and then they join with him in pouring evil thought upon the poor sufferer. And this goes on day after day, and is done not by one man but by thousands. Do you begin to see how base, how terrible a sin this is? You must avoid it altogether.

1790s
Context: To preserve the freedom of the human mind then and freedom of the press, every spirit should be ready to devote itself to martyrdom; for as long as we may think as we will, and speak as we think, the condition of man will proceed in improvement. The generation which is going off the stage has deserved well of mankind for the struggles it has made, and for having arrested the course of despotism which had overwhelmed the world for thousands and thousands of years. If there seems to be danger that the ground they have gained will be lost again, that danger comes from the generation your contemporary. But that the enthusiasm which characterizes youth should lift its parricide hands against freedom and science would be such a monstrous phenomenon as I cannot place among possible things in this age and country.
