Never studied philosophy before, but I fail to see how step 2 – he needs to be justified in believing what he believes- makes it knowledge. I would classify that as a level above knowledge, understanding. The first and third are enough for knowledge. You can know for certainty that something is true wothout having a justifiable reason. (Ex: My head hurts. No clue why. The justifiable reason cannot be that it hurts me. Thats the fact.)
Also how is Chaim justified in believing that the person who gets the job will have ten coins in hos pocket. He can take them out etc. It’s a silly transitive (whatever its called) because its extremely sbject to change.
Also knowledge is only worth something when you can identify what the knowledge is. Chaims “knowledge” may end up turning out true, but he didn’t realize how. Hardly qualifies as knowledge.
And btw, I’m pretty sure oyyoyoy means it shouldn’t be a big deal, because how exactly is figuring this out going to change your life other than giving you some intellectual pleasure?
