No desire is more natural than the desire for knowledge. We assay all the means that can lead us to it. When reason fails us we make use of experience. Experience is a weaker and less dignified means: but truth is so great a matter that we must not disdain any method that leads us to it.

[Il n’est desir plus naturel que le desir de cognoissance. Nous essayons tous les moyens qui nous y peuvent mener. Quand la raison nous faut, nous y employons l’experience. Qui est un moyen de beaucoup plus foible et plus vil. Mais la verité est chose si grande, que nous ne devons desdaigner aucune entremise qui nous y conduise.]

Michel de Montaigne (1533-1592) French essayist

Essays, Book 3, ch. 13 “On Experience [De l’Experience]” (1588) (3.13) (1595) [tr. Screech (1987)]

Aristotle's Metaphysics opens with the phrase "All men by nature desire knowledge."

The 1595 edition included a quotation from Manilius inserted after the word "experience" (omitted here). It also added the second descriptor (after "weaker") of how experience compares to reason.

There is no desire more naturall, then that of knowledge. We attempt all meanes that may bring us unto it. When reason failes us, we employ experience. Which is a meane by much more, weake and vile. But trueth is of so great consequence, that wee ought not disdaine any induction, that may bring us unto it.
[tr. Florio (1603)]

There is no Desire more natural than that of Knowledge: We try all Ways that can lead us to it; where Reason is wanting, we therein employ Experience which is a Means much more weak and cheap. But Truth is so great a thing, that we ought not to disdain any Mediation that will guide us to it.
[tr. Cotton (1686)]

[tr. Cotton/Hazlitt (1877)]

There is no desire more natural than the desire for knowledge. We make trial of all means that can lead us to it. When reasoning fails us, we then make use of experience, which is a much feebler and lower means; but truth is so great a thing that we must not disdain any medium that leads us to it.
[tr. Ives (1925)]

There is no desire more natural than the desire for knowledge. We try all the ways that can lead us to it. When reason fails us, we use experience, which is a weaker and less dignified means. But truth is so great a thing that we must not disdain any medium that will lead us to it.
