In philosophy, particularly in ethics, the pragmatic maxim (WP) states that an object may be considered solely in terms of its effects on the surrounding context. In the special case of ethics, the maxim states that the ethical ramifications of an event are summarized by its physical effects upon the future.
In mathematics, particularly in category theory, Yoneda's lemma (WP, nLab) states that in a universe of transformations, an object is equivalent to all of the transformations which can be applied to it. In the special case of category theory, where everything is either an object or a one-way transformation between objects, Yoneda's lemma states that an object is equivalent to the collection of all transformations which start with that object.
Both of my summaries are not very deep, but a serious reader should hopefully notice the similarity between these two statements. I have found exactly one such reader. Can anybody find other philosophers who have noticed this overlap?
The goal would be to phrase the pragmatic maxim as yet another special case of Yoneda's lemma.
