Final answer:
To exploit traits such as boldness and initiative, one must cultivate them actively, akin to muscles or skills. Human nature's inclination to create and assert dominance requires ambition and rationality, tempered with realistic expectations and societal adaptability.
Step-by-step explanation:
To exploit the human traits such as boldness, initiative, strength of will, and imagination use, one must cultivate these characteristics akin to a muscle or a skill that improves with exercise and deliberate application. Referencing the texts, we can see that intelligence used strategically in warfare, for instance, demonstrates one's ability to plan and make calculated decisions. The virtue of enterprise is important in endeavors such as leading armies to combat or achieving success in various fields, requiring preparation and the cultivation of inherent abilities.
As Aristotle noted, virtues are not passive traits; but rather, are developed through action. By engaging in brave acts, one becomes brave. This extends to the abstract notion that human nature is inclined toward creation and asserting dominance over the environment for the sake of enhancing and enjoying life. It is this combination of ambition, creativity, and rationality that forms the bedrock of human advancement. However, the texts also suggest managing expectations and rejecting fantastical dreams, channeling our aspirations within the constraints of reality.
Conclusively, to fully exploit boldness, initiative, strength of will, and imagination, one must engage in a continuous process of learning, practicing, and challenging oneself, while remaining adaptable to the ever-changing definitions of success and virtue in society.
