Posthumanism is a difficult concept to grasp. Academic essays can often be exceedingly intricate and often obnoxious. Nayar in this book simplifies his language but not at the expense of the complexity of the topic. Although I've read a lot about posthumanism before, I do think that out of the books I've read on the topic, Nayar's style of writing is the most accessible for people newer to the topic or who (like me) struggle with some of the genomic/biological debate around it.
The book is structured very clearly, lay out in sections easy to navigate. As well as this, he touches upon biological advances, but takes time to explain why these are relevant to the debate and often situates them alongside literary or sociological discourse to help aid your understanding.
The points he makes are exceedingly relevant and frequently made me pause to really take not and question them. I wrote a lot of notes reading this, and I highly recommend doing the same if you're reading, because it helps to digest and understand and remember the vast quantity of information in here.
