"Science is a first-rate piece of furniture for a man's upper chamber, if he has common sense on the ground floor"

This quote by Oliver Wendell Holmes is a metaphor for the value of science in our lives. He is saying that science is like a furniture piece in a man's upper chamber, or his mind. It is an important property, but just if the guy also has good sense on the ground floor, or in his everyday life. Simply put, science is only helpful if it is integrated with useful knowledge and knowledge. Science can provide us with understanding and understanding, but it is only beneficial if we use it in a practical way. We must utilize our common sense to apply the knowledge we get from science to our everyday lives. Without good sense, science is just a collection of facts and theories that are of no usage to us.
