Autor de Sapiens, bestseller del momento con más de diez millones de copias vendidas en todo el mundo.

Sapiens es un recorrido por nuestro pasado.
Homo Deus, una mirada a nuestro futuro.
21 lecciones para el siglo XXI es una exploración de nuestro presente.

¿Cómo podemos protegernos de las guerras nucleares, los cataclismos ecológicos o las tecnologías disruptivas? ¿Qué podemos hacer contra la propagación de la posverdad o la amenaza del terrorismo? ¿Qué debemos enseñar a nuestros hijos?

Con la misma prosa inteligente, fresca y provocadora, Harari vuelve a librerías con un nuevo título, 21 lecciones para el siglo XXI, en el que examina algunas de las cuestiones más urgentes de nuestro presente. El hilo dorado que recorre este estimulante nuevo libro es el desafío de mantener nuestro enfoque colectivo e individual frente al constante y desorientador cambio que estamos viviendo.

¿Somos aún capaces de entender el mundo que hemos creado?


ENGLISH DESCRIPTION

In Sapiens, he explored our past; in Homo Deus he looked to our future. Now, one of the most innovative thinkers on the planet turns to the present to make sense of today's most pressing issues.

Religion, terrorism, war, politics, fake news, human migration, the environment, nationalism. 21 Lessons for the 21st Century is a probing investigation into the big subjects that we are confronting on a daily basis in the media and in our lives, and the issues of crucial importance to understand as we move into the unchartered territory of the future. As technology advances faster than our understanding of it, hacking becomes a tactic of war, terrorism and fundamentalism rise, and the world feels more polarized than ever, Harari makes sense of it all and raises the important questions we need to ask ourselves if we are to survive. In 21 accessible chapters that are both provocative and profound, he provides advice on how to think about these topics and how to act in order to prepare for a future unlike anything we can dream of. Few writers of nonfiction have captured the imaginations of millions of readers in quite the astonishing way Harari has managed. His unique ability to look at where we have come from and where we are going has gained him fans from every corner of the globe. There is an immediacy and accessibility to this new book that makes it essential reading for anyone interested in navigating the world today.

Great for night time play!
Size: One-Size-for-Most
This ball is great! It is a 2-for-one light up feature so we love the flashing lights and if she drops it in the snow after those lights stop, we can still find it because of the strong glow that gets its charge from the flashing LED lights. Our first one lasted a few years, we lost it on a trip so now back for our second one so we can keep the night time fetch going! She is a golden retriever for size reference. Any bigger of a breed and I would worry it might be too small for her mouth. It’s a bit smaller than a tennis ball. Just don’t make the same mistake I did and let them have it in the house at night, she walked up to my bedside while I was asleep one night and squeezed it to activate it. Those lights are so bright it was a rude awakening!

Good option for playing at night
Size: One-Size-for-Most
This ball is a good option if your dog likes to fetch at night. It stays lit for about 20 minutes or so, but that is me only leaving it out of the counter, being "charged" by whatever house lights are on. My dog isn't a big chewer, but it seems as though it would hold up well. I like that it is easy to rinse and clean. It seems to be a good value.

Night play
Size: One-Size-for-Most
My dog like many other dogs loves to play. We needed a ball that fit into the handheld thrower we had but something that we could find it at night. This has been wonderful!

It stopped working after three play sessions
Size: One-Size-for-Most
I thought this ball was great until a week later it stopped blinking and got lost in the snow. We only played with it for three days for 20 minutes at a time. It should’ve lasted a lot longer.

It’s absolutely perfect for fetch in the dark!
Size: One-Size-for-Most
We needed to find a glow in the dark ball to run our over active dog after dark ( gets dark now about 5 pm ish) I was hesitant to buy this ball at first. We went to try it out and it totally blew my expectations! The ball really glows, it’s a durable rubber and when it hits the ground it lights up blue and red. Incredibly satisfied and just ordered 2 more. If you need to run your dog in the dark, this is absolutely for you. Highly recommend it
