Voltaire: Frases en inglés (página 8)

Qu’est-ce que la tolérance? c’est l’apanage de l’humanité. Nous sommes tous pétris de faiblesses et d’erreurs; pardonnons-nous réciproquement nos sottises, c’est la première loi de la nature.
"Tolerance" (1764)
Citas, Dictionnaire philosophique (1764)

C'est une des superstitions de l'esprit humain d'avoir imaginé que la virginité pouvait être une vertu.
Notebooks (c.1735-c.1750)
This quotation and the three that follow directly below are from the so-called Leningrad Notebook, also known as Le Sottisier; it is one of several posthumously published notebooks of Voltaire.

This attribution to Voltaire appears in Strauss' Familiar Medical Quotations (1968), p. 394, and in publications as early as 1956 http://books.google.pt/books?id=lCtCAQAAIAAJ&q=%22Doctors+are+men+who+prescribe+medicine+of%22&dq=%22Doctors+are+men+who+prescribe+medicine+of%22&hl=pt-PT&sa=X&ei=mbnWUsvDIfTB7Aaw_YD4Dw&redir_esc=y; the quotation in French does not, however, appear to be original, and is probably a relatively modern invention, only quoted in recent (21st century) published works, which attribute it to "Voltaire" without citing any source.
Original: (fr) Les médecins administrent des médicaments dont ils savent très peu, à des malades dont ils savent moins, pour guérir des maladies dont ils ne savent rien.

Original: (fr) C'est le privilège du vrai génie, et surtout du génie qui ouvre une carrière, de faire impunément de grandes fautes.

"Canon Law: Ecclesiastical Ministry" (1771)
Questions sur l'Encyclopédie (1770–1774)
Original: (fr) La vertu suppose la liberté, comme le transport d’un fardeau suppose la force active. Dans la contrainte point de vertu, et sans vertu point de religion. Rends-moi esclave, je n’en serai pas meilleur. Le souverain même n’a aucun droit d’employer la contrainte pour amener les hommes à la religion, qui suppose essentiellement choix et liberté. Ma pensée n’est pas plus soumise à l’autorité que la maladie ou la santé.

Variants:
No oaths, no seals, no official mummeries were used; the treaty was ratified on both sides with a yea, yea — the only one, says Voltaire, that the world has known, never sworn to and never broken.
As quoted in William Penn : An Historical Biography (1851) by William Hepworth Dixon
William Penn began by making a league with the Americans, his neighbors. It is the only one between those natives and the Christians which was never sworn to, and the only one that was never broken.
As quoted in American Pioneers (1905), by William Augustus Mowry and Blanche Swett Mowry, p. 80
It was the only treaty made by the settlers with the Indians that was never sworn to, and the only one that was never broken.
As quoted in A History of the American Peace Movement (2008) by Charles F. Howlett, and ‎Robbie Lieberman, p. 33

"Prayers" (1770)
Questions sur l'Encyclopédie (1770–1774)
Original: (fr) 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.

The History of the Quakers (1762)

The viceadmiral thought his son crazy; but soon discovered he was a Quaker. He then employed every method that prudence could suggest to engage him to behave and act like other people. The youth answered his father only with repeated exhortations to turn Quaker also. After much altercation, his father confined himself to this single request, that he would wait on the king and the duke of York with his hat under his arm, and that he would not "thee" and "thou" them. William answered that his conscience would not permit him to do these things. This exasperated his father to such a degree that he turned him out of doors. Young Penn gave God thanks that he permitted him to suffer so early in His cause, and went into the city, where he held forth, and made a great number of converts; and being young, handsome, and of a graceful figure, both court and city ladies flocked very devoutly to hear him. The patriarch Fox, hearing of his great reputation, came to London — notwithstanding the length of the journey — purposely to see and converse with him. They both agreed to go upon missions into foreign countries; and accordingly they embarked for Holland, after having left a sufficient number of laborers to take care of the London vineyard.

The most surprising circumstance is that this letter, though written by an obscure person, was so happy in its effect as to put a stop to the persecution.

Variants:
He looked on everything as imitation. The most original writers, he said, borrowed one from another. Boyardo has imitated Pulci, and Ariofio Boyardo. The instruction we find in books is like fire; we fetch it from our neighbour, kindle it as home, communicate it to others, and it becomes the property of all.
Historical and Critical Memoirs of the Life and Writings of M. de Voltaire (1786) by Louis Mayeul Chaudon, p. 348
What we find in books is like the fire in our hearths. We fetch it from our neighbors, we kindle it at home, we communicate it to others, and it becomes the property of all.
As translated in Geary's Guide to the World's Great Aphorists (2008), by James Geary, p. 373
Original: (fr) Ainsi, presque tout est imitation. L’idée des Lettres persanes est prise de celle de l’Espion turc. Le Boiardo a imité le Pulci, l’Arioste a imité le Boiardo. Les esprits les plus originaux empruntent les uns des autres. Michel Cervantes fait un fou de son don Quichotte; mais Roland est-il autre chose qu'un fou? Il serait difficile de décider si la chevalerie errante est plus tournée en ridicule par les peintures grotesques de Cervantes que par la féconde imagination de l'Arioste. Métastase a pris la plupart de ses opéras dans nos tragédies françaises. Plusieurs auteurs anglais nous ont copiés, et n'en ont rien dit. Il en est des livres comme du feu de nos foyers; on va prendre ce feu chez son voisin, on l’allume chez soi, on le communique à d’autres, et il appartient à tous.
