The superstitious man is to the knave, what the slave is to the tyrant; nay more — the superstitious man is governed by the fanatic, and becomes a fanatic himself.

Life is thick sown with thorns, and I know no other remedy than to pass quickly through them. The longer we dwell on our misfortunes, the greater is their power to harm us.

[La vie est hérissée d’épines, & je ne sçais d’autre remède, que de passer vite à travers ces broussailles. C’est donner de la consistance aux maux, que de trop s’y arrêter.]

To learn who rules over you, simply find out who you are not allowed to criticize.

Voltaire (1694-1778) French writer [pseud. of Francois-Marie Arouet]
(Misattributed)

Frequently attributed to Voltaire in memes, but unsourced in any of his writings. More accurately attributed to Kevin Alfred Strom during a 1993 anti-semitic screed on a radio broadcast:

To determine the true rulers of any society, all you must do is ask yourself this question: Who is it that I am not permitted to criticize?

I disapprove of what you say, but I will defend to the death your right to say it.

Voltaire (1694-1778) French writer [pseud. of Francois-Marie Arouet]
(Misattributed)
(Source)

The words are not found in any Voltaire and actually belong to historian Evelyn Beatrice Hall, writing as S. G. Tallentyre in The Friends of Voltaire (1906), describing an 1759 incident where Voltaire learned that Claude-Adrien Helvétius' book On the Mind [De l’esprit] had been burned (along with Voltaire's own "On Natural Law") after condemnation by the Paris Parliament and the Sorbonne.

‘What a fuss about an omelette!’ he had exclaimed when he heard of the burning. How abominably unjust to persecute a man for such an airy trifle as that! ‘I disapprove of what you say, but I will defend to the death your right to say it,’ was his attitude now.

Hall later wrote to a friend that the actual words were her own and ought not to have had quotation marks.

Variations:

I wholly disapprove of what you say -- and will defend to the death your right to say it.
Monsieur l’Abbé, je déteste ce que vous écrivez, mais je donnerais ma vie pour que vous puissiez continuer à écrire.

Voltaire -- Candide, ch. 23 (1759) [tr. Adams (1966)]

In this country it is useful from time to time to kill one admiral in order to encourage the others.

[Dans ce pays-ci il est bon de tuer de tems en tems un Amiral pour encourager les autres.]

Voltaire (1694-1778) French writer [pseud. of Francois-Marie Arouet]
Candide, ch. 23 (1759) [tr. Adams (1966)]
(Source)

As Candide witnesses the (real-life) 1757 execution of English Admiral John Byng, who withdrew his undermanned ships from a naval battle during the French invasion of Minorca at the beginning of the Seven Years War. Byng was scapegoated for poor condition of the Mediterranean fleet, and court martialed for "failing to do his utmost" in the battle, which carried an automatic death penalty. In real life, Voltaire had been one of the people who attempted to intervene on Byng's behalf. In the book, Candide is so appalled by the injustice, he refuses to touch ground on English soil.

The last few words ("pour encourager les autres") are frequently quoted on their own referring to any harsh punishment used as an example to incent those who follow.

Voltaire -- Questions sur l’Encyclopédie, “Prayers,” (1770-1774)

Dave — Wed, 16 Jul 2008 09:31:22 +0000

The Eternal has his designs from all eternity. If prayer is in accord with his immutable wishes, it is quite useless to ask of him what he has resolved to do. If one prays to him to do the contrary of what he has resolved, it is praying that he be weak, frivolous, inconstant; it is believing that he is thus, it is to mock him. Either you ask him a just thing, in which case he must do it, the thing being done without your praying to him for it, and so to entreat him is then to distrust him; or the thing is unjust, and then you insult him. You are worthy or unworthy of the grace you implore: if worthy, he knows it better than you; if unworthy, you commit another crime by requesting what is undeserved.

In a word, we only pray to God because we have made him in our image. We treat him like a pasha, like a sultan whom one may provoke or appease.

[L’Éternel a ses desseins de toute éternité. Si la prière est d’accord avec ses volontés immuables, il est très inutile de lui demander ce qu’il a résolu de faire. Si on le prie de faire le contraire de ce qu’il a résolu, c’est le prier d’être faible, léger, inconstant; c’est croire qu’il soit tel, c’est se moquer de lui. Ou vous lui demandez une chose juste; en ce cas il la doit, et elle se fera sans qu’on l’en prie; c’est même se défier de lui que lui faire instance ou la chose est injuste, et alors on l’outrage. Vous êtes digne ou indigne de la grâce que vous implorez: si digne, il le sait mieux que vous; si indigne, on commet un crime de plus en demandant ce qu’on ne mérite pas.

En un mot, nous ne faisons des prières à Dieu que parce que nous l’avons fait à notre image. Nous le traitons comme un bacha, comme un sultan qu’on peut irriter ou apaiser.]

Voltaire -- Questions sur les miracles (1765)

Dave — Wed, 11 Jun 2008 10:45:06 +0000

Formerly there were those who said: You believe things that are incomprehensible, inconsistent, impossible because we have commanded you to believe them; go then and do what is unjust because we command it. Such people show admirable reasoning. Truly, whoever is able to make you absurd is able to make you unjust. If the God-given understanding of your mind does not resist a demand to believe what is impossible, then you will not resist a demand to do wrong to that God-given sense of justice in your heart. As soon as one faculty of your soul has been dominated, other faculties will follow as well. And from this derives all those crimes of religion which have overrun the world.

[Il y a eu des gens qui ont dit autrefois: Vous croyez des choses incompréhensibles, contradictoires, impossibles, parce que nous vous l’avons ordonné; faites donc des choses injustes parce que nous vous l’ordonnons. Ces gens-là raisonnaient à merveille. Certainement qui est en droit de vous rendre absurde est en droit de vous rendre injuste. Si vous n’opposez point aux ordres de croire l’impossible l’intelligence que Dieu a mise dans votre esprit, vous ne devez point opposer aux ordres de malfaire la justice que Dieu a mise dans votre coeur. Une faculté de votre âme étant une fois tyrannisée, toutes les autres facultés doivent l’être également. Et c’est là ce qui a produit tous les crimes religieux dont la terre a été inondée.]

Sometimes misattributed to Oscar Wilde. This is part of a canto added from another Voltaire piece, probably by a publisher, to the end of the 1756 edition of Voltaire's poem, as noted in the "Additional Notes" included with 19th Century editions of the work. It reads in part:

O gift from heaven! tender love! sweet desire!
We are still happy with your image:
Illusion is the first of all pleasures.

[O don du ciel! tendre amour! doux désir!
On est encore heureux par votre image;
L'illusion est le premier plaisir.]

The canto was not included the Voltaire-authorized 1762 edition. The English translation of the quoted line goes back at least to 1881.

You are perfectly right, Sire. A wise and courageous prince, with money, troops, and laws, can perfectly well govern men without the aid of religion, which was made only to deceive them; but the stupid people would soon make one for themselves, and as long as there are fools and rascals there will be religions.
