“The hunger and thirst for knowledge, the keen delight in the chase, the good humored willingness to admit that the scent was false, the eager desire to get on with the work, the cheerful resolution to go back and begin again, the broad good sense, the unaffected modesty, the imperturbable temper, the gratitude for any little help that was given - all these will remain in my memory though I cannot paint them for others.”

“C'est l'inconnu qui excite l'ardeur des savants, qui, dans le seul connu, se flétriraient.”

“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.”
