Quote by Daniel J. Boorstin
The greatest obstacle to discovering the shape of the earth, the continents, and the oceans was not ignorance but the illusion of knowledge.
Summary
This quote suggests that the major hindrance in uncovering the true nature of the earth, including its shape, continents, and oceans, is not lack of knowledge, but rather the assumption of possessing knowledge. It implies that when individuals firmly believe they already understand something, they may close themselves off to new possibilities and hinder the progress of discovery. Thus, the quote reminds us of the importance of questioning our assumptions and maintaining an open mind in the pursuit of knowledge and understanding.
