"The deadliest foe to virtue would be complete self-knowledge"

This quote by F. H. Bradley suggests that having complete expertise of oneself can be damaging to one's moral character. It suggests that if one were to have a complete understanding of their own ideas, sensations, and also motivations, it might bring about an absence of self-constraint as well as a disregard for principles. This could be because if one were to have a full understanding of their own weaknesses, they may be more likely to give in to lure and also act in ways that are not in accordance with their values. Additionally, if one were to have a complete understanding of their very own toughness, they might be most likely to act in manner ins which are self-seeking and egotistical. In either situation, having total self-knowledge can result in an absence of merit. Consequently, it is very important to keep a balance between understanding oneself and maintaining a moral compass.
