  1. Survey of Precursors Of Category Theory
    inquiryintoinquiry.com/2023/04

    A few years ago I began a sketch on the “Precursors of Category Theory”, tracing the continuities of the category concept from Aristotle, to Kant and Peirce, through Hilbert and Ackermann, to contemporary mathematical practice. A Survey of resources on the topic is given below, still very rough and incomplete, but perhaps a few will find it of use.

    One of my favorite mathematical tricks — it almost seems too tricky to be true — is the #PropositionsAsTypesAnalogy. And I see hints the 2-part analogy can be extended to a 3-part analogy, as follows.

    \(\text{proof hint : proof : proposition :: untyped term : typed term : type}\)

    Re: R.J. LiptonMathematical Tricks

    One of my favorite mathematical tricks — it almost seems too tricky to be true — is the Propositions As Types Analogy.

    And I see hints the 2‑part analogy can be extended to a 3‑part analogy, as follows.

    See my working notes on the Propositions As Types Analogy for more information.
