Δαφνη Ευτυχια Αρθουρος

"Il est juste que ce qui est juste soit suivi; il est nécessaire que ce qui est le plus fort soit suivi.
 La justice sans la force est impuissante, la force sans la justice est tyrannique.
 La justice sans force est contredite, parce qu'il y a toujours des méchants. La force sans la justice est accusée. Il faut donc mettre ensemble la justice et la force, et pour cela faire que ce qui est juste soit fort ou que ce qui est fort soit juste.
 La justice est sujette à dispute. La force est très reconnaissable et sans dispute. Aussi on n'a pu donner la force à la justice, parce que la force a contredit la justice et a dit qu'elle était injuste, et a dit que c'était elle qui était juste.
 Et ainsi ne pouvant faire que ce qui est juste fût fort, on a fait que ce qui est fort fût juste.
   -- Blaise Pascal (b. 1623-06-19, d. 1662-08-19), Pensées (published posthumously in 1669) [quoted passage appears on 17th page of the linked PDF, but as Wikipedia notes, "The proper order of the Pensées is heavily disputed." Bold emphasis added (same applies to translations below).]

Translated by Honor Levi ( Pensées and Other Writings, Oxford University Press, 1995):

It is just to follow justice. It is necessary to follow the strongest.
Justice without strength is powerless. Strength without justice is tyranical.
Justice without strength is a contradiction because there are always wicked people. Strength without justice is an indictment. So justice and strength must be joined, and for that, what is just must be made strong, or what is strong, just.
Justice lays itself open to wrangling. Strength is clearly recognizable and cannot be argued with. So we have been unable to combine strength with justice because strength has overturned justice, has said justice is unjust, and claimed justice for itself.
So, having been unable to strengthen justice, we have justified strength.

Translated by C. Kegan Paul The Thoughts of Blaise Pascal, Kegan Paul, Trench & Co., 1885):

It is just that what is just should be obeyed, it is of necessity that what is strongest should be obeyed.
Justice without power is unavailing, power without justice is tyrannical. Justice without power is gainsaid, because the wicked always exist, power without justice is condemned. We must therefore combine justice and power, making what is just strong, and what is strong just. Justice is subject to dispute, power is easily recognised and cannot be disputed. Thus we cannot give power to justice, because power has arraigned justice, saying that justice is unjust, and she herself is truly just; so since we are unable to bring about that what is just should be strong, we have made the strong just.

Translator not named in front matter; may be M. Brunschvicg? ( Pascal's Pensées, E.P. Dutton &anp; Co., Inc, 1958):

It is right that what is just should be obeyed; it is necessary that what is strongest should be obeyed. Justice without might is helpless; might without justice is tyrannical. Justice without might is gainsaid, because there are always offenders; might without justice is condemned. We must then combine justice and might, and for this end make what is just strong, or what is strong just.

Justice is subject to dispute; might is easily recognised and is not disputed. So we cannot give might to justice, because might has gainsaid justice, and has declared that it is she herself who is just. And thus being unable to make what is just strong, we have made what is strong just.

According to Google Translate:

It is right that what is right be followed; it is necessary that what is strongest be followed.
Justice without force is powerless, force without justice is tyrannical.
Justice without force is contradicted, because there are always bad people. Force without justice is accused. It is therefore necessary to put justice and force together, and for that to make that what is just is strong or that what is strong is just.
Justice is subject to dispute. The strength is very recognizable and without dispute. So we could not give force to justice, because force contradicted justice and said that it was unjust, and said that it was she who was just.
And so, being able to do only what was right was strong, we made what was strong was right.
