"If any philosopher had been asked for a definition of infinity, he might have produced some unintelligible rigmarole, but he would certainly not have been able to give a definition that had any meaning at all"

This quote by Bertrand Russell is describing the concept of infinity and how it is difficult to specify it in a significant method. Russell is suggesting that if a thinker were asked to define infinity, they would likely produce a long and complex response that would not make any sense. This is because infinity is an abstract concept that is beyond our understanding and can not be explained in an easy meaning. Russell is indicating that infinity is something that is beyond our understanding and can not be totally understood. This quote highlights the difficulty of attempting to specify something that is so vast and complex. It also works as a tip that there are some things in life that are just beyond our understanding.
