Most great minds are way beyond the understanding and tolerance  of the contemporaries'. The very special character that differs genius from mediocrity also prevent them being understood by the rest of hte world, So here comes the saying that great minds can be decided by later generation , not by their peers. I have to admit the fact that there were plenty of genius scorned and banished by his peers, however, not all great minds suffer from this.
When regarding the nature science fields, we can discover a dozen of cases like that. The spirit and essence of science determines that its purpose is to discover the truth beneath the surface and explore the unknown areas. It's a tough progress during which persistence and endeavor are siginificantly crucial for that it may take years before finding the truth finally. And also, the significant meaning of a certain finding could wait decades before the world recognize its value .

When it comes to fields such like arts and literaure, many a many artists striving for their lived to be recognized and accepted by the majority however end up anonymous. Vincent Van Gogh, who is regarded as one of the greatest painter of history, could not sell even a piece of painting while he is alive! Art serves to reveal the inner emotion of artist and convey them through their work. When their understanding of beauty and goodness or their expression of their subjective thoughts are beyond the comprehension of the majority , they are meant to be lonely and anonymous for most of their lives.
However in today's business world,  there is no room for nameless genius and anonymous inventions. In the realm of business, in most cases, great achievement is recognized immediately . More convincing is the field of business: the names such as Bill Gates and Mark Zurkerberg, are eminet because they fullfils billions of people's dream: to be young and weathy. nothing else. We appreciate these persons as great ones because we live in a time when the criteria of success is wealth. So it lead us to think,
