Is it unlikely that an author would write a work is on his or her own values and beliefs?

It's highly unlikely that an author would *completely* avoid expressing their values and beliefs in their work. Even seemingly objective works, like historical accounts or scientific papers, reflect the author's biases in their selection of information, the way it's presented, and the conclusions drawn.

While an author might consciously try to suppress their personal views, it's almost impossible to entirely separate oneself from one's worldview. Values and beliefs inevitably shape an author's:

* Choice of subject matter: What stories they choose to tell reflects their interests and what they consider important.

* Character development: Characters' motivations, flaws, and ultimate fates often mirror the author's own moral compass, even if subtly.

* Narrative style and tone: The author's voice and perspective inevitably seep into the writing style.

* Themes and messages: Even if not explicitly stated, underlying themes often reflect the author's beliefs about the world.

Therefore, while an author might not explicitly preach their beliefs, it's far more likely their work will implicitly reflect them in many ways.
