The ancient Greek philosopher who had the biggest influence on St. Thomas Aquinas's philosophy is Aristotle.

Explanation:

St. Thomas Aquinas, a medieval philosopher and theologian, was heavily influenced by Aristotle's works, particularly in the areas of metaphysics, ethics, and epistemology. Aquinas adapted and integrated Aristotle's ideas into Christian theology, arguing that reason and faith are harmoniously intertwined. He utilized Aristotelian concepts such as substance, form, and the nature of God, providing a philosophical foundation that helped shape medieval scholastic thought. While Plato, Plotinus, and Socrates also contributed to philosophical discourse, it is Aristotle whose empirical approach and rational methodology significantly impacted Aquinas's intellectual framework. This influence is most clearly seen in Aquinas’s emphasis on the use of reason in understanding faith and moral philosophy.
