Mencius 7A.36: position changes a person's air
Mencius says environment and nurture reshape a person's bearing. Position is not neutral; it slowly forms voice, reaction, and moral atmosphere.
孟子自范之齊,望見齊王之子,喟然嘆曰:「居移氣,養移體,大哉居乎!夫非盡人之子與?」孟子曰:「王子宮室、車馬、衣服多與人同,而王子若彼者,其居使之然也。況居天下之廣居者乎?魯君之宋,呼於垤澤之門。守者曰:『此非吾君也,何其聲之似我君也?』此無他,居相似也。」
Mencius, going from Fan to Qi, saw the king of Qi's son at a distance, and said with a deep sigh, 'One's position alters the air, just as the nurture affects the body. Great is the influence of position! Are we not all men's sons in this respect?' Mencius said, 'The residence, the carriages and horses, and the dress of the king's son, are mostly the same as those of other men. That he looks so is occasioned by his position. How much more should a peculiar air distinguish him whose position is in the wide house of the world! 'When the prince of Lu went to Song, he called out at the Die Shi gate, and the keeper said, "This is not our prince. How is it that his voice is so like that of our prince?" This was occasioned by nothing but the correspondence of their positions.'

Central question

Direct answer
Because human beings are not pure will detached from setting. Long habitation in a place and order gradually shapes bearing, reaction, and even voice.
First principle
A person is formed not only by intention but by environment. To ignore setting is to overestimate will and underestimate institutional formation.
Why it matters
This passage serves searches around environment, formation, social position, and why Mencius treats order as morally formative.
