But I do not approve of what I see in use, that is, to seek to affirm and support our religion by the prosperity of our enterprises. Our belief has other foundation enough, without going about to authorize it by events: for the people being accustomed to such plausible arguments as these and so proper to their taste, it is to be feared, lest when they fail of success they should also stagger in their faith.

[Mais je trouve mauvais ce que je voy en usage, de chercher à fermir & appuyer nostre religion par la prosperité de nos entreprises. Nostre creance a assez d’autres fondemens, sans l’authoriser par les evenemens. Car le peuple accoustumé à ces argumens plausibles, & proprement de son goust, il est danger, quand les evenemens viennent à leur tour contraires & des-avantageux, qu’il en esbranle sa foy.]

Michel de Montaigne (1533-1592) French essayist

Essay (1572), “That a Man Is Soberly to Judge of the Divine Ordinance [Qu’il faut sobrement se mesler de juger des ordonnances divines], Essays, Book 1, ch. 31 (1.31) (1595) [tr. Cotton/Hazlitt (1877)]
    (Source)

This chapter name has multiple disparate translations, e.g.:

• "Hazarding an Opinion on God’s Plans Demands Caution"
• "That a Man must not be too hasty in judging of Divine Ordinances"
• "We should meddle soberly with judging divine ordinances"
• "Judgements on God’s ordinances must be embarked upon with prudence"
• "That It Is With Sobriety That We Should Undertake to Judge of the Divine Decrees"

Some editions and translations use the older 1588 chapter order, and refer to this as chapter 32, as noted below.

But I utterly disalow a common custome amongst us, which is to ground and establish our religion upon the prosperitie of our enterprises. Our beleefe hath other sufficient foundations, and need not be authorized by events. For the people accustomed to these plausible arguments, and agreeing with his taste, when events sort contrarie and dis-advantageous to their expectation, they are in hazard to waver in their faith.
[tr. Florio (1603)]

But I do not approve of what I see in use, that is, to seek to establish and support our religion by the prosperity of our enterprises. Our belief has other foundations enough, without authorising it by events; for people accustomed to such plausible arguments as these, and so peculiar to their own taste, it is to be feared, lest when they fail of success, they should also stagger in their faith.
[tr. Cotton (1686)]

But I think ill of what I see to the customary -- the seeking to strengthen and support our religion by the prosperity of our undertakings. Our belief has enough other foundations, without giving authority to it by events; for if the people become accusomed to these arguments, which are plausible and suited to their taste, there is a danger that when, in turn, adverse and disadvantageous events happen, their faith will be shaken by them.
[tr. Ives (1925), 1.32]

But I think that the practice I see is bad, of trying to strengthen and support our religion by the good fortune and prosperity of our enterprises. Our belief has enough other foundations; it does not need events to authorize it. For when the people are accustomed to these arguments, which are plausible and suited to their taste, there is a danger that when in turn contrary and disadvantageous events come, this will shake their faith.
[tr. Frame (1943), 1.32]

What I consider wrong is our usual practice of trying to support and confirm our religion by the success or happy outcome of our undertakings. Our belief has enough other foundations without seeking sanction from events: people who have grown accustomed to such plausible arguments well-suited to their taste are in danger of having their faith shaken when the turn comes for events to prove hostile and unfavourable.
[tr. Screech (1987), 1.32]
