"The greatest obstacle to discovering the shape of the Earth, the continents, and the oceans was not ignorance - it was the illusion of knowledge." -- Daniel Boorstin (1914-2004) Former Librarian of Congress
I have written a lot about this lately. See, if you think you know something, you cannot learn what is really there to learn. What we as humans accept as the way that it is, is actually the greatest obstacle to growth.
The whole world knew the earth was flat. And this was the greatest obstacle to learning it was round.
Everyone knew man could not run a mile in less than 4 minutes. And for years, no one did it until Roger banister didn’t believe them. Even in the face of doctors telling him he would die if he did it.
With this I always wonder. What is it that we ‘think’ we know today, that is really an illusion of knowledge? What do we think is just the way it is, a fact, commonly accepted, that is getting in the way of true knowledge.
Be careful to believe that anything just “is” a certain way. That might be limiting you from attaining true knowledge.
