I've always felt that Isaac Asimov writes brilliant science fiction with boring characters. I love a good time travel story, mostly to see what this author's take on the usual time travel paradoxes will be. Anyone who writes about agents changing history has to explain how they deal with things like the Grandfather Paradox, meeting earlier or later versions of yourself, and so on. There are a handful of well-known ways to deal with these issues (alternate timelines, a deterministic universe, spe ...more

Final review, first posted on Fantasy Literature:

Re-reading a favorite book from your teenage years is always a risky endeavor. I’ve been dismayed by how often my youthful memories are tarnished by a re-read, and I end up wondering if my taste as a young adult was all in my mouth.


But I couldn’t resist trying The End of Eternity (1955) by Isaac Asimov again, partly because I remembered liking it so well as a teenager, but my memories of it were so extremely hazy (for the longest time, until a Goo

If you haven't read Asimov's SF classic, it's one of those time-travel stories where you can change the past. The people with the time machines are a shadowy, infinitely powerful organisation called the Eternals. They flit around in time, changing things "for the good of humanity". Except that, as I'm sure you already guessed, it isn't quite clear after a while that humanity is benefiting from all this attention. The agents who are responsible for making the changes are called Technicians, and t ...more

I just had to do a little retro SF catch-up, grabbing those old classics by big-name SF authors that I haven't yet had the pleasure to read, and this one kept cropping up as one of the best of the best by Asimov.

You know, OTHER than Foundation and the Robot novels. Of which, a few are sub-par. We'll ignore all of these for now and focus on this standalone.

Nutshell: antisocial nerd, responsible for historical amendments to spacetime continuum, dicks it up for everyone in order to lose virginity.

Eternity is an interdimensional NGO, set up in the 27th century (32), initially to carry on intertemporal trade (43), which trade was promoted as its primary purpose. Its true primary task is to "prevent catastrophe from striking mankind" and "to breed out of Reality any factors that might lead to such knowledge" of its biotemporal management of human histo

In many ways, an absolute masterpiece of classic science fiction. Asimov's best stand-alone novel, which is kind of by default due to his other great work Foundation being a series and most of his other science fiction works to be short stories. (And yes, I know The End of Eternity in an indirect way does connect to Foundation.)

The time travel mechanics are mind-boggling in all the best ways. The concept of Eternity which manipulates time century by century, erasing entire realities by constantl

This is a unique one for Asimov, and not connected to his usual fictional universe. Ironically, this is his first book I tried to read, in Malayalam translation, no less! But either the translation was bad, or the story was untranslatable, or I was too young for it... I dropped it after a few pages. I am glad I did, because I could read the original afresh.

This story is about a group called Eternals who travel outside of linear time, stepping in when required within the time-stream to make thing

Even though I tend to pick them apart, I love stories dealing with time-travel. Most end up creating what should be a paradox or forget little things that I tend to pick up on. Not this one. Asimov did a spectacular job. I thought I had him a couple of times but he covered everything.

Eternity, in this case, is something separate from our reality. The people who live there, the Eternals, have the ability to tweak our reality to produce different outcomes from those that occurred naturally. They s

Less than 200 pages. The same material nowadays would be expanded to at least 600 pages or probably a trilogy.

Well cool ideas:

* The time shafts are powered by our Sun going supernova in the distant future.
* Idealogical debate between Utilitarianism and ‘adventure’. (And fighting for frontiers) or ‘short term’ safety vs risk and long term growth.
* Everything that happens is intricately played out according to the central plot driver

I suppose because SF writers feel obliged to provide ‘characters

Asimov is doing a couple of things here that raise a dull story to interesting, but you won't be able to catch it until the final two chapters. Dare I say this is a feminist critique of society?... I mean, as critical as a '50s dude from sexist academia could deliver? And delivered in quite possibly the most offensive way possible, at least to modern sensibilities? It partly serves as a polemic against critics of the space program (I smell a colleague confrontation brewing, Asi), partly an effor ...more

I loved this! It is very rare for e to like classic literature, and even though I love science fiction, classic sci-fi bores me with its dry writing style or dull characters. But this book! The cool ideas about time travel, science and society glued me to its pages! The writing style was okay and characters were tolerable.

This is somehow my first Asimov book. At first, I was underwhelmed. However, as the book went forward, I found that there was much more depth to the writing than originally met the eye and that the shallow characters were shallow with a purpose.

Asimov sets up a group of scientist who are outside of time called the Eternals. While everyone on earth thinks that their main job is to facilitate commerce between various centuries, their true function is to manipulate history to make it play out more

I'm a SF buff, a big Asimov fan, and I'd rate this book among his very best. Having read through most of Asimov's Robot and Foundation series, what drew me to read The End of Eternity was the often mentioned fact that this book describes why Asimov's fictional universe panned out the way it did. And I wasn't disappointed. What a story!

One of the things I like most about Asimov's SF is how small and insignificant it makes you feel when it speaks about millions of inhabited planets spread across t
4.0 to 4.5 Stars. Superb Asimov story and his best novel not set within the Foundation and Robot Universe.
Time Travel!

I am a huge fan of time travel, particularly when it's done well. And, should I expect anything less in the hands of Asimov? Long before we learned how to harness the pathways of time and to make the proper adjustments to each time reality, Asimov bequeathed to us this incredible novel that postulates a world where there me travel exists in a corridor known as Eternity and the Eternals, who live in this narrow corridor, travel tens of thousands of years in something like Wonka's gia

I recently watched a TV series called Steins;gate. It started out as a lighthearted comedy, where a self-proclaimed mad scientist creates a time machine that allows him to send text messages into the past, by making the plate in his microwave turn backwards. It was really funny and entertaining, and then it went really, really dark as all of the consequences to changes in the past that they made with the machine started hitting, and they spent the rest of the series trying to undo or otherwise f ...more

Lately, I’ve been a bit nostalgic for classic sci-fi and I’ve been reading some Heinlein and Asimov. I somehow missed this book when I tore through all the Asimov novels way back in my youth. I enjoyed this book, but it does have a significant flaw. The basic premise is mankind’s establishment of Eternity in the 27th century that allowed trade of goods from one century to another. However, those that controlled Eternity also controlled human history.

This book is amazing. I would say that Asimov is amazing too, but since I’ve only read The End of Eternity, and given the great amount of books that he wrote, that wouldn’t be fair. But nevertheless, the Asimov I saw there is amazing and that’s enough.

Short books are a dangerous thing. They seem the perfect choice if one wants to read but has little time, but may become an endless torment (like Crash) or a time-consuming obsession (like The End of Eternity). In both cases you need to end the bo
Apr 04, 2015 rated it it was amazing  ·  review of another edition
In a way, it's unfortunate that so much of Asimov's fiction falls into his massive future history of Foundations and robots and galactic empires. And then, in the 80's, Asimov littered his canon with so many subpar prequels and refits and bridges that the few singletons he had were even further buried beneath the onslaught. And that's too bad, because The End of Eternity is the best novel Asimov ever wrote.

It has all the hallmarks of his best work, the supremely cool high concept, the strict lo

I love going back to the classics. It’s fun to see what inspired modern-day novelists and screenwriters when they were kids. The End of Eternity, by Isaac Asimov, surely inspired cool stories like The Adjustment Bureau, Fringe, 12 Monkeys, Looper, and Primer.

Check it out: the story is told from the perspective of an “Observer” whose job it is to tweak history so that the aggregate majority of humans live in the highest achievable state of happiness. Just outside of Time is this place called Eter

ENGLISH: This book is quite similar to "Guardians of time" by Poul Anderson, but in a certain sense it is also its opposite. In both cases, time travel is supposed to be possible and the present can be changed by manipulating the past. But in Anderson's series of stories, our far descendants stage the time guardians to prevent those changes in the past that would affect their own existence. What happens in Asimov's novel is quite the opposite. This is understandable, for the end of the novel mak ...more

Andrew Harlan bothered me with the way he jumped to conclusions and then proceeded to interpret everything based upon those unjustified conclusions. However, I loved the premise and Asimov gives the reader some unexpected twists in the final quarter of the book.
This book made me think about time travel and space exploration like no other book has done before.

Re-read of an SF Classic.

There are numerous time travel stories in the literature, including Timescape by Gregory Benford and Dark Matter by Blake Crouch with their multiplying timelines, but this early entry by the master Isaac Asimov, is one of the leading examples of the immutable timeline. In The End of Eternity, mankind has discovered the secret of time travel, and in the process further determined that there is only one reality or timeline, which can be changed to a large or small degree

This is vintage Asimov, a novel exuding brilliance in imagination and intelligent philosophising of possible future realities. How better to muse about what different realities we can face about the future from near to far to...eternity, without the plot device of time travelling. Asimov puts this plot device to great use by exploring the various destinies that human motives can achieve or fall victim of. The story ingeniously threads these philosophical questions and tells a story about eternit ...more

I don't know whether I began reading Asimov's nonfiction or fiction works first. I do know that I wrote a fan letter to him and actually got a reply back. Granted, it was a form-letter postcard but it was still pretty "cool" that I was "corresponding" with an actual author.

I was also very selective in what I read. I enjoyed the first three books of the Foundation but I never had any desire to read any of the Robot novels, and subsequent Foundation novels were disappointing (with the brilliant ex

I hate the two main characters, Harlan and Noys, and it is their relationship, as described in the book, makes no sense for me whatsoever. Insta love is already a pet peeve of mine, but the irrational behavior that is caused by it in this book is next level bullshit.
