“In the sciences, the authority of thousands of opinions is not worth as much as one tiny spark of reason in an individual man.”

“In questions of science, the authority of a thousand is not worth the humble reasoning of a single individual.”

“Sì perché l'autorità dell'opinione di mille nelle scienze non val per una scintilla di ragione di un solo, sì perché le presenti osservazioni spogliano d'autorità i decreti de' passati scrittori, i quali se vedute l'avessero, avrebbono diversamente determinato.For in the sciences the authority of thousands of opinions is not worth as much as one tiny spark of reason in an individual man. Besides, the modern observations deprive all former writers of any authority, since if they had seen what we see, they would have judged as we judge.”

“One test result is the worth one-thousand expert opinions.”

“One good test is worth a thousand expert opinions.”

“What is reasoning? It is the result of doing away with the vital distinction which separates subjectivity and objectivity. As a form of abstract thought reasoning is not profoundly dialectical enough; as an opinion and a conviction it lacks full-blooded individuality. But where mere scope is concerned, reasoning has all the apparent advantage; for a thinker can encompass his science, a man can have an opinion upon a particular subject and a conviction as a result of a certain view of life, but one can reason about anything.”
