1. Oh, take a chill pill, Putin...
Sometimes people get behind on things in life and need a quick refresher or a lifeline to get by.
(I'd recommend a quick search on Wikipedia next time though, grking--I tell my students when they approach me for Shakespeare tutoring that No Fear Shakespeare/Sparknotes isn't that great...just read Wikipedia for the plot so you're not lost, and then read the actual play, because so much of what makes Shakespeare or any great author is in the language ITSELF, so just get the plot outline out of the way so you're not lost, and then focus on the language.)
You should always read the book, but sometimes, people get behind...as long as he doesn't plagiarize for a paper or anything, who cares that he got the book summary? Half the time the books' back cover/introduction itself has a summary.
Besides, one of the most overrated of sayings is "Cheaters never prosper"...pretty sure just about every successful businessman out there cheated at some time...
As long as he doesn't make a habit out of it, who cares? Even good students get behind and need a crutch sometimes...again, as long as he doesn't copy/paste that into a paper, what's it matter that he comes to class having read a synopsis?
2. You really SHOULD read this book though, grking, it's a masterpiece! :)
There's also a really good 2008 BBC miniseries version of it that I'd recommend, it's pretty faithful to the book and well acted.
3. "So our resident socialist par excellence wants to corporatize education and turn the youth into mindless clogs for the capitalist machine who just unthinkingly "get the job done". Wonderful."
"Mindless cogs for the capitalist machine"...you're just a walking self-parody at this point, aren't you?
(To say nothing of the "mindless cogs for the communist regime" in North Korea, Stalinist Russia, and Maoist China, but no, unthinking masses only occur and are only ever used in capitalist countries because alskdfaksdjfaisjodfiajiosdf. And you can quote me on that.)
4. I ask this as the absurd gushing literature fan round about these parts...
So long as he isn't copy/pasting it into an essay or otherwise using it to cheat his grade, what's so wrong with reading a plot summary?
Plots are only part of a work's value...our good buddy and Cheater Extraordinaire, Shakespeare, ripped off just about every single one of his plots...and has subsequently seen HIS plots ripped off as well (see: every ripoff of a Romeo and Juliet or Taming of the Shrew-style story, ever) and yet, with all those plots being ripped off, we still seem to value his above others most of the time.
There are only so many story "types" in the world...so you will have repetition...
Knowing the plot of Tess is nowhere near as important as delving into Hardy's juxtaposing the old with the new, nature with the D'Urbervilles home, his treatment of religion, Tess/Angel in nature vs. Tess/Angel in society, the socio-economic conditions which preempt Tess's actions, and on and on and on...
The plot is just the skeleton, while all the other elements make up the STORY, and THAT is the important thing (and why you should after this really read the book, grking.) :)
But for one class period, as long as it's just so he's not totally lost, who cares if someone spoils the plot for him? It doesn't dilute Hardy's message, it only spoils the story for him somewhat, and as long as he's not plagiarizing for a paper, why should you stand up and act indignantly towards a guy just trying to get by in class?
