“All our knowledge has its origin in our perceptions”

“All our knowledge hast its origins in our perceptions … In nature there is no effect without a cause … Experience never errs; it is only your judgments that err by promising themselves effects such as are not caused by your experiments … Science is the observation of things possible, whether present or past; prescience is the knowledge of things which may come to pass.”

“The knowledge of all things is possible”

“Art is the queen of all sciences communicating knowledge to all the generations of the world.”

“All sciences are vain and full of errors that are not born of Experience, the mother of all Knowledge.”

“The organ of perception acts more readily than judgment.”

“Our life is made by the death of others.”
