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

“It is the unknown that excites the ardor of scholars, who, in the known alone, would wither.”

“He who asks a question is a fool for five minutes. He who does not ask a question is a fool forever. O-# It is the constant and determined effort that breaks down resistance and sweeps away all obstacles.”

“As a rule, he or she that has the most information will have the greatest success in life.”

“The only people who achieve much are those who want knowledge so badly that they seek it while the conditions are still favorable. Favorable conditions never come.”
