Mark Hayes sees Aristotle’s ‘reciprocal exchange’ under the perspective of calculating the ‘just price’ of products when the relative ‘merit or worth’ of their producers is given ‘prior to exchange’—the inverted commas marking expressions in his comment. Strictly speaking, his comment goes beyond the article to which it refers. The article’s main intention has been to abstain from questions of justice and to concentrate on ‘geometrical accounting’ as is stated by its title.

回复海斯

马克·海斯（Mark Hayes）在计算产品的“正价”时，将生产者的相对“价值或价值”给予“交换前”，即计算价格的“正当价格”，这就是亚里士多德的“互惠交换”。严格来说，他的评论超出了它所引用的文章。这篇文章的主要目的是放弃司法问题，而将注意力集中在标题所指的“几何会计”上。
