Recently, there has been a revival in taking empirical magnitudes seriously. Weights, heights, velocities and the like have been accepted as abstract entities in their own right rather than just equivalence classes of objects. The aim of my paper is to show that this revival should include value magnitudes. If we posit such magnitudes, important value comparisons (cross-world, cross-time, mind to world, cross-theory, cross-polarity, ratio) can be easily explained; it becomes easier to satisfy the axioms for measurement of value; goodness, badness, and neutrality can be given univocal definitions; value aggregation can be given a non-mathematical understanding which allows for Moorean organic unities. Of course, this does not come for free. One has to accept a rich ontology of abstract value magnitudes, but, to quote David Lewis, ‘The price is right; the benefits in theoretical unity and economy are well worth the entities.’

近来，认真对待经验量已经复苏。重量，高度，速度等本身已被接受为抽象实体，而不仅仅是对象的等价类。我的论文的目的是表明这种复兴应包括价值数量级。如果我们设定这样的数量级，就可以很容易地解释重要的价值比较（跨世界，跨时间，心智对世界，跨理论，跨极性，比率）。满足价值度量公理变得更容易；善，恶和中立可以用明确的定义来表示；可以通过非数学的理解来实现价值汇总，从而实现摩尔人有机统一。当然，这不是免费的。人们必须接受丰富的抽象价值量级的本体论，但是引用大卫·刘易斯的话来说，“价格是正确的；价格是合理的。理论上的团结和经济上的利益是实体所应得的。”
