Answer:
The belief that sensory experience is the key to all knowledge
Step-by-step explanation:
Rene Descartes was born in 1596 in France. He proposed a philosophy that advocated the belief that sensory experience is the key to all knowledge. This philosopher motivated the people to never believe in the false and always to doubt what is being said by someone. This philosophy suggested a new view of nature, which nullified the moral and religious significance of the time, for which reason Descartes came into conflict with the church that banned all his books in 1663.
