In simple terms, the statement suggests that individuals who are inherently unscrupulous or deceitful do not require guidance from books or external teachings to engage in harmful or manipulative behavior; they naturally act on their instincts and tendencies without needing instruction. This implies that such people's nature dictates their actions, making them prone to unethical conduct regardless of whether they have read about it.
On a deeper level, this quote also touches upon the idea that certain behaviors are intrinsic rather than learned from external sources like books or mentors. It suggests that ethical principles and moral guidance are essential for individuals who might otherwise lack an inherent sense of right and wrong. The statement highlights the importance of understanding human nature and the varying motivations behind actions. For those who naturally incline towards manipulation, rules and guidelines serve as crucial tools to foster positive behavior and prevent harmful acts. Additionally, it underscores the complexity of assessing someone's character based solely on their actions or lack thereof; some individuals may not need external prompts to behave badly because unethical conduct stems from their core values rather than a lack of knowledge about what is right.
