All our knowledge has its origin in our preceptions.
Science, its principles and rules (1148—1161)
1148.
Science is the observation of things possible, whether present or past; prescience is the knowledge of things which may come to pass, though but slowly.
1149.
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.
