Although nature commences with reason and ends in experience it is necessary for us to do the opposite, that is to commence with experience and from this to proceed to investigate the reason.
Experience does not err. Only your judgments err by expecting from her what is not in her power.
Experience does not ever err; it is only your judgment that errs in promising itself results which are not caused by your experiments
Wisdom is the daughter of experience.
Nature is full of infinite causes that have never occurred in experience.
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.
Experience never errs; it is only your judgments that err by promising themselves effects such as are not caused by your experiments.
Every instrument requires to be made by experience.
