This book is hugely important, and if you are willing to give it a chance (and have some kind of idea about the big strands of French academia in the 1960s) it can be hugely rewarding. That said, Derrida is NOT an easy writer at the best of times, compounded by the fact that this book covers an enormous breadth of topics and Derrida was (according to the rumor-mill) high most of the time he wrote it. That said it proposes the basic derridean structures of writing and trace things which (IMO) have been unbelievably influential in academia, from queer theory to aftopessimism. It’s a good read, but only if you are willing to put up with its b.s.
