"Ignorance more frequently begets confidence than does knowledge: it is those who know little, and not those who know much, who so positively assert that this or that problem will never be solved by science"

This quote by Charles Darwin talks to the power of lack of knowledge and how it can result in overconfidence. He suggests that it is those who do not have knowledge, rather than those who possess it, who are most likely to make strong and sweeping declarations about what science can and can not do. He indicates that those who are ignorant of a subject are more likely to be overconfident in their assertions, while those who are educated are most likely to be familiar with the limitations of science. This quote works as a tip that knowledge is power, which it is very important to be aware of what one does not know in order to avoid making unproven claims.
