It seems to me that the point still thinking was expressing is that some people do not have the opportunity to search for truth. Their life is often short and predefined. This is an Interesting point because truth is what we actually live.
What happens whether on earth or in outer space is real it is truth. Most of what happens throughout the universe is still a mystery to us. We observe as best we can and consider the observations and conclusions that others have reached.
Pondering the whys and wherefores is possible because most people can now read and write and have the means to analyze their existence. It sometimes seems that language is not an adequate tool for understanding deeper truth. Mathematics comes closer but some things are not quantifiable.
Truth is not a rigid set of beliefs. Once we think we posses the truth, we close our minds to other possibilities. In that moment we lose our connection with the infinite.
