Aristotle (-384–-322) is a classic author whose works are in the public domain.

Aristotle's ethical philosophy moves beyond abstract moralizing to examine virtue as a habit developed through practice and choice, offering a framework for thinking about character that remains more grounded than most modern self-help.

Aristotle's surprisingly readable treatise on art and storytelling becomes a blueprint for understanding how humans create meaning, making it as relevant to screenwriting and narrative design as it was to ancient Greek drama.
