This is better than the original essay as published because “the notation has been modernized, some of the archaisms have been removed, and what seem to be obvious printer’s errors have been corrected.”

Daniel’s uncle, Jacob Bernoulli, wrote Ars Conjectandi, published posthumously in 1713. Daniel distinguishes between the monetary value of an event and its utility. Bayes isn’t concerned with this distinction, but he clearly means to define the probability of an event as the ratio of its expected utility to the utility realized if it occurs.

Blitzstein JK, Hwang J. Introduction to probability. Second edition. Boca Raton: CRC Press; 2019.

My favorite probability textbook. Look for Joseph Blitzstein’s Stat 110 lectures on YouTube. This book and the other probability textbooks on my shelf (see list below) present the probability axioms, basic rules, and definitions — what Price calls “the general laws of chance” — in roughly the same order that Bayes does in Section 1 of this essay. Except for Jaynes, they all use the notation of set theory.

The following books all identify $P(A \cap B) = P(A)P(B|A)$ as the “multiplication rule”:

As we will see, Bayes couldn’t find a good approximate solution to his problem when the number of successes and failures are both large (>15). Laplace found one 20 years later. Dale shows that Price, building on Bayes’s analysis, got close.

Jaynes ET, Bretthorst GL. Probability theory: the logic of science. Cambridge, UK; New York, NY: Cambridge University Press; 2003. 727 p.

Jaynes presents probability as an extension of logic. In other words, he extends reasoning about the truth of a proposition to reasoning about its plausibility. His approach is more general than the Kolmogorov system of probability with its use of set notation, but since that is the approach taken by Blitzstein and the other textbooks on my shelf, I will use set notation in my comments. Jaynes refers to propositions that are true or false; the other books (and Bayes) refer to events that either occur or fail to occur.

Before his “General Theory of Employment, Interest and Money”, Keynes published this book on probability theory, which according to Dale (see above), presents the odds form of Bayes’s Rule.

Laplace, Pierre Simon. 1814. “A Philosophical Essay on Probabilities” Blackmore Dennett. Kindle Edition. Published 2019.

This is Laplace’s write-up of lectures that he delivered in 1795 to “the normal schools” where he had been called by the national convention as a professor of mathematics. It covers the same material as his “Analytical Theory of Probabilities”, but without the equations. This is the 1902 English translation by F.W. Truscott and F.L.Emory.

See Chapter 3: Inverse Probability. Stigler differs from some others on the nature of Bayes’s key insight.

An interesting article about Richard Price and especially his appendix to Bayes’s essay.
