Context

“Experience, the interpreter between formative nature and the human race, teaches how that nature acts among mortals; and being constrained by necessity cannot act otherwise than as reason, which is its helm, requires her to act. 1150. Wisdom is the daughter of experience. 1151. Nature is full of infinite causes that have never occured in experience. 1152. Truth was the only daughter of Time. 1153. Experience never errs; it is only your judgments that err by promising themselves effects such as are not caused by your experiments. Experience does not err;” source
