How does the idea of the unknown play a role in the philosophy of Lord of the Rings?

In J.R.R. Tolkien's Lord of the Rings trilogy, the concept of the unknown plays a significant role in exploring the nature of the heroes of the story. The unknown is frequently represented as a source of fear, uncertainty, and danger, challenging the characters and their established beliefs.

Throughout the story, the characters encounter the unknown, whether it be the vast and mysterious forests, the treacherous mountains, or the unspeakable horrors of Sauron's armies. Yet, despite the danger and uncertainty, the characters also find power and growth in the face of what they do not or cannot know. Frodo, for example, gains strength from his willingness to undertake a perilous task without knowing its full extent, while Aragorn is forced to confront his fear of taking up his true identity as a king and leader.

The philosophy of Lord of the Rings, therefore, emphasizes the importance of confronting the unknown, pushing beyond one's established boundaries, and embracing the uncertainty and fear that come along with it. By doing so, the characters grow in strength and character, demonstrating that fear and uncertainty need not be obstacles to be avoided, but rather opportunities for growth and transformation.
