Default Einstein Derived the Lorentz Equations from ... the Lorentz Equations

In 1905 Einstein derived the Lorentz equations from the constancy of the speed of light, but where did Einstein take the constancy from? He "borrowed" it from the Lorentz equations - it is as simple as that:

Albert Einstein: "...I introduced the principle of the constancy of the velocity of light, which I borrowed from H. A. Lorentz's theory of the stationary luminiferous ether..." https://en.wikipedia.org/wiki/Lorentz_ether_theory

Default Einstein Derived the Lorentz Equations from ... the Lorentz Equations

This text, only slightly euphemistic, contains the whole truth about Einstein's relativity:

Banesh Hoffmann, Relativity and Its Roots, p.92: "Moreover, if light consists of particles, as Einstein had suggested in his paper submitted just thirteen weeks before this one, the second principle seems absurd: A stone thrown from a speeding train can do far more damage than one thrown from a train at rest; the speed of the particle is not independent of the motion of the object emitting it. And if we take light to consist of particles and assume that these particles obey Newton's laws, they will conform to Newtonian relativity and thus automatically account for the null result of the Michelson-Morley experiment without recourse to contracting lengths, local time, or Lorentz transformations. Yet, as we have seen, Einstein resisted the temptation to account for the null result in terms of particles of light and simple, familiar Newtonian ideas, and introduced as his second postulate something that was more or less obvious when thought of in terms of waves in an ether. If it was so obvious, though, why did he need to state it as a principle? Because, having taken from the idea of light waves in the ether the one aspect that he needed, he declared early in his paper, to quote his own words, that "the introduction of a 'luminiferous ether' will prove to be superfluous." https://www.amazon.com/Relativity-It.../dp/0486406768

The most important points:

1. The Michelson-Morley experiment was directly compatible with the variable speed of light posited by Newton's emission theory of light.

2. The Michelson-Morley experiment was incompatible with the constant (independent of the motion of the emitter) speed of light "without recourse to contracting lengths, local time, or Lorentz transformations".
