Frase de Gaston Bachelard

“Science is the product of a thought process that refuses the obvious and is built against what is merely perceived.”

“Knowledge of the real is a light that always casts some shadows.”

“One cannot possess the truth without having corrected an error, without having discovered an error.”

“Opinion thinks poorly; it does not think: it translates needs into knowledge.”

“For the scientific mind, all knowledge is an answer to a question. If there is no question, there can be no scientific knowledge.”
