Good behaviour and high moral character must come first, for unless the character be trained, acquiring knowledge will only prove injurious. Knowledge is praiseworthy when it is coupled with ethical conduct and virtuous character; otherwise it is a deadly poison, a frightful danger. A physician of evil character, and who betrayeth his trust, can bring on death, and become the source of numerous infirmities and diseases.
