If I were to suggest two books to read this year, they would be “Brief Answers to the Big Questions,” by the renowned cosmologist Stephen Hawking, who died in 2018, and “Sapiens: A Brief History of Humankind,” by the historian Yuval Noah Harari. Both present lucid insights into what might happen after we die and the stories we tell ourselves to explain why we die.
Of heaven and superhumans
Writers have attempted to explain the origins of the universe as well as looking into the future. Before his death Stephen Hawking predicted the rise of 'superhumans.' and a new phase of what he called “self-designed evolution.”

“Do I have faith?” asks Hawking, who could only communicate using his facial muscles due to a progressive motor neuron disease, in his book. “We are free to believe what we want, and it’s my view that the simplest explanation is that there is no God,” he writes. “No one created the universe and no one directs our fate. This leads me to a profound realization: There is probably no heaven and afterlife either.”
Hawking argues that “the universe was spontaneously created out of nothing, according to the laws of science” in “an event we now call the Big Bang” and, therefore, no divine explanation for our existence is needed.
Billions of years later, after the planet presented the necessary conditions for the emergence of life and, eventually, of humans, we started searching for explanations. And this is where Harari’s insights into the wonderful history of humankind begins.
Despite a near universal desire for an end to Venezuela’s manmade disaster, sending in U.S forces to take out the Maduro regime would be counter-productive. It should be categorically rejected by interim president Juan Guaidó, not to mention the Trump administration.
The firing of undocumented workers at Trump's golf clubs just shows how the practice of employing immigrants without legal work papers is much more common than we might imagine. Such is life in the United States.
The Trump administration should be wary of fueling fake news predictions about an imminent American invasion which unrealistically raises expectations about Maduro's removal.
At some point we will have to accept the fact that the border between Mexico and the United States is nothing more than an invention.
The United States has had a major role in the evolving drama of the fight for democracy in Venezuela and Nicaragua. And so far, it’s been surprisingly coordinated, a veritable model of multilateralism.
Has the Maduro regime reached breaking point? It remains hard to say, but tomorrow is another - more hopeful - day for the restoration of democracy in the South American nation.
It’s impossible to get into Trump’s head but what comes out of his mouth are racist remarks. But, saddest of all are the millions who tolerate his views, cheer him on and emulate his behavior.
The time is well past due for the U.S. government to conduct a thorough review of leaders and their senior colleagues before they leave office to determine if they merit visas.
Harari explains that we have invented many myths and legends in an attempt to explain everything that happens to us, and this is precisely what defines us and sets us apart from other animals. “This ability to speak about fictions is the most unique feature of Sapiens language,” writes Harari. “It’s relatively easy to agree that only Homo sapiens can speak about things that don’t really exist, and believe six impossible things before breakfast. You could never convince a monkey to give you a banana by promising him limitless bananas after death in monkey heaven.”
Harari contends that it is this collective imagination that enables us to believe in “common myths” and allows strangers to cooperate successfully with each other, which is “why Homo sapiens came to dominate the planet.” This is precisely what separates us from bees, ants and chimpanzees.
In the future, Hawking predicts the rise of “superhumans.” He proposes that humankind is entering a new phase of “self-designed evolution,” in which we will be able to change and improve our DNA in order to become more intelligent and less aggressive, and resist the diseases that kill us.
At first glance, this seems like something to look forward to. If cancer, diabetes, sclerosis and heart disease could be eradicated, we could live longer and considerably improve our quality of life. Still, this kind of genetic engineering, this ability to tinker with our DNA, could cause a great division among humankind.
“Once such superhumans appear,” Hawking writes, “there are going to be major political problems with the unimproved humans, who won’t be able to compete. Presumably, they will die out, or become unimportant. Instead, there will be a race of self-designing beings, who are improving themselves at an ever-increasing rate.” Once life expectancy is longer, Hawking suggests, the human race will be able to colonize other planets.
He also predicts that while laws will likely be passed against genetic engineering, the temptation will be too hard to resist. This, of course, sounds rather troubling, like a delirious science-fiction scenario. Both Harari and Hawking are extraordinary examples of scientists who never stop asking questions and are not afraid to posit what some answers might look like.
Hawking, who died at age 76, also humbly reflects on the meaning and purpose of his life in his book: “I don’t have a grudge against God,” he writes. “I do not want to give the impression that my work is about proving or disproving the existence of God. My work is about finding a rational framework to understand the universe around us. For centuries, it was believed that disabled people like me were living under a curse that was inflicted by God. Well, I suppose it’s possible that I’ve upset someone up there, but I prefer to think that everything can be explained another way. ...”
Both these books offer, without a doubt, another way of looking at the big questions.
