Rudolf Schuessler has argued that sixteenth-century thinkers developed a concept of equal probability that was virtually absent before 1500 and that may have contributed to the birth of mathematical probability shortly after 1650. This note uses additional textual evidence to argue that the concept of equal probability was in fact generally available to medieval thinkers. It is true that ascriptions of equal probability are comparatively rare in medieval texts, but this can be explained without positing a conceptual blind spot.

关于 1500 之前的等概率的注释

鲁道夫·舒斯勒 (Rudolf Schuessler) 认为，16 世纪的思想家发展了一种等概率概念，这种概念在 1500 年之前几乎不存在，但可能促成了 1650 年后不久数学概率的诞生。本文使用额外的文本证据来论证等概率概念事实上，中世纪的思想家普遍可用。诚然，等概率归因在中世纪文本中相对较少，但这可以在不设置概念盲点的情况下进行解释。
