| Quote #1 [..] a painted table in the corner on which lay a few manuscripts and books; the dust that lay thick upon them showed that they had been long untouched. (1.3.1) |
Aha! Proof that Raskolnikov hasn't been doing his homework, and evidence that he's dropped out of school. Dostoevsky belabors this point so we understand that education is a big issue here.
| Quote #2 [Marmeladov:] "[…] but Katerina Ivanovna, my spouse, is a person of education and an officer's daughter." (1.2.18) |
The narrator tells us later that Katerina's education is what allows her to maintain a certain "dignity" and pride through all of her trial and tribulations. The suggestion is that education has value beyond helping one get that dream job. It can also be a source of sustenance. We don't know if Katerina is the best character to demonstrate that point.
| Quote #3 [Dounia:] "Pyotr Petrovitch [Luzhin] makes no secret of the fact that he had a cheap education, he is proud indeed of having made his own way." (3.3.124) |
Did you find it odd that Dounia has a better education than Luzhin, yet she can't get a decent job and he can? This is because very few professional positions were open to women in Russia (and elsewhere) in the 1860s.
