I just learned about the "All things being equal" tool in philosophy and am trying to see if the following passage from Plato's Republic is an example of it. The snippet from the passage goes like this:
If it is complete lack of perception, like a dreamless sleep, then death would be a great advantage. For I think that if one had to pick out that night during which a man slept soundly and did not dream, put beside it the other nights and days of his life, and then see how many days and nights had been better and more pleasant than that night, not only a private person but the great king would find them easy to count compared with the other days and nights. If death is like this I say it is an advantage, for all eternity would then seem to be no more than a single night.
I have an inner intuition that this is an example of using Ceteris Paribus but I'm not really sure how to locate it exactly. English isn't my first language so I'm wondering if someone could help me pinpoint if this is actually an example or not.
