"There is a degree of depravity in mankind which requires a certain degree of circumspection and distrust."

To point out the importance of circumspection in your conduct, it may be proper to observe that a good moral character is the first essential in a man, and that the habits contracted at your age are generally indelible, and your conduct here may stamp your character through life. It is therefore highly important that you should endeavor not only to be learned but virtuous.
