According to Mark Twain, "standards" are the lasting ideas people have, whereas "fashions" are just temporary trends or beliefs that change across the years.
<u>As an example of "standards,"</u> Twain cites Shakespeare because, for centuries, his pieces have been adopted and recreated by people worldwide.
<u>As an example of "fashions,</u>" Twain considers the different styles of music, writing, and technology being the latter the most changing with the passing of time.
