The Essence of the 'Great Treatise A': A Philosophical Inquiry into the Gentleman's Establishment of Life and the Order of the *Yi*

This article deeply interprets the core proposition from the 'Great Treatise A'—'That which the gentleman dwells in and finds peace is the order of the *Yi*.' It examines how the gentleman, by internalizing the Way of Heaven and Earth and utilizing the *Book of Changes* as the foundation for establishing his life, achieves a state of 'auspiciousness without detriment' through observing the images and contemplating the textual explanations, situated within the Pre-Qin context and the Confucian tradition.

V. The Four Dimensions and the Four Human Faculties

From the perspective of human cognitive abilities, the four dimensions correspond to different faculties:

  • Observing Images—Requires the faculty of "intuition": the ability to directly perceive the implied imagery and atmosphere from the hexagram figures.
  • Contemplating Words—Requires the faculty of "understanding": the ability to deeply grasp the meaning and logic of language.
  • Observing Changes—Requires the faculty of "insight": the ability to keenly perceive the trend and direction of transformation.
  • Contemplating Divinations—Requires the faculty of "judgment": the ability to synthesize various pieces of information to make correct decisions.

The comprehensive development and coordinated use of these four faculties—intuition, understanding, insight, and judgment—is the core competency the Yi seeks to cultivate.

This resonates internally with the Confucian sequence of cultivation outlined in the Great Learning (Da Xue 大学): "investigation of things, extension of knowledge, sincerity of the will, rectification of the mind, cultivation of the self, ordering of the family, governing the state, and bringing peace to the world." Investigating things and extending knowledge require intuition and understanding; sincerity of will and rectification of the mind require insight; cultivating the self and governing the world require judgment.
