He should not adopt an unquestioning belief of his teacher and his textbook. He studies the fact, examines the scientific arguments, and makes an assessment of the reliability of the information. If he has doubts, he should reserve his judgement until such time as when he is able to investigate the accuracy of the information for himself. To a Buddhist, confidence is a product of reason, knowledge and experience. When it is developed, confidence can never be blind faith. Confidence becomes a power of the mind to understand the nature and the meaning of life.
