פֶּ֭תִי יַאֲמִ֣ין לְכָל־דָּבָ֑ר וְ֝עָר֗וּם יָבִ֥ין לַאֲשֻׁרֽוֹ׃
O simples dá crédito a tudo; mas o prudente atenta para os seus passos.
Sichot HaRan
It's much better to be a "Fool that believes in everything", meaning, to believe even in nonsense and falsehoods in order to thereby also arrive at the truth than to be a wise man that doubts everything,
