Most religions embrace and promote certain notions about the meaning of life, offering the faithful reasons why we and all other organisms exist. Indeed, perhaps the fundamental definition of religious faith is the belief that life serves a (divine) purpose. Science, however, has always given a resounding "no" to the question "Does life have a higher meaning?"
At least until now.
In a series of lectures and in a forthcoming book, science writers Eric Schneider and Dorion Sagan argue that even from a scientific perspective, life does serve a purpose, and thus does have a meaning that transcends the self. They arrived at this conclusion when trying to reconcile a contradiction that has long puzzled those who study both biology and physics.
Living organisms obviously embody arrangements of matter into complex structures. They transform chemicals and, in an orderly fashion, transport and store them in purposeful ways. Above the level of individual organisms, they form societies and ecosystems. All of us are familiar with these fundamental biological notions, and we are all part of these processes. Order seems to be the name of the biological game, and evolution leads to more complex organisms and more organized structures.
This is, of course, at odds with one of the fundamental principles of physics: the second law of thermodynamics, which holds that entropy -- the degradation of all matter and energy in the universe to an ultimate state of inert uniformity -- increases as a result of each and every process. The more the world develops the more disorder there will be. Physics even accepts the idea that entropy defines the direction of time. In the end everything will be broken down and randomly distributed.
How do Schneider and Sagan reconcile the contradiction between what appears true of life -- that it organizes matter into increasingly complex creatures and structures -- and the notion that disorder should increase and order should be lost? Equally important, how can science see any meaning of life in the reconciliation of that apparent contradiction?
The bottom line is that the second law of thermodynamics rules and that the existence of life helps increase entropy. In other words, life promotes disorder. Some might think that this could be true only if the logical end of evolution and intelligent life were to be a nuclear explosion that pulverized Earth. But that is not what Schneider and Sagan mean. Instead, they make a distinction between matter and energy and say that matter organized in structures disseminates energy gradients faster than randomly distributed matter.
As one example, they consider a phenomenon of which beer drinkers have long been aware. If you want to empty a bottle of water (or beer) and turn it upside down, the water will come out in uneven glugs. If you spin the bottle and create an eddy inside it, the water will flow out much faster and more smoothly. The eddy in the bottle is a structure in the water. Water running down is matter losing its potential energy. The structure speeds up the dissemination of the energy gradient.
Similarly, on a hot day, the air in a forest is cooler than over adjacent bare lands, thanks to evaporation and transpiration in the trees. The energy gradient, in this case that of heat, is disseminated more effectively by the structure of the forest and the life within it.
The more complex the structure the more effective is the energy dissemination. Populations are better in this respect than single individuals; ecosystems even more so, and most effective of all -- so far -- are human high-tech societies.
Thus, goes the argument, the second law of thermodynamics is not contrary to the existence of life; rather, it is the cause of life. That law drives evolution to higher levels of complexity and to more sophisticated societies and technologies for the sole purpose of disseminating energy gradients.
So life, at long last, has a higher meaning in the eyes of science -- even if serving the second law of thermodynamics is not exactly what the religiously faithful had in mind.

They did it again. For the whole world to see: an image of a Taiwan flag crushed by an industrial press, and the horrifying warning that “it’s closer than you think.” All with the seal of authenticity that only a reputable international media outlet can give. The Economist turned what looks like a pastiche of a poster for a grim horror movie into a truth everyone can digest, accept, and use to support exactly the opinion China wants you to have: It is over and done, Taiwan is doomed. Four years after inaccurately naming Taiwan the most dangerous place on
Wherever one looks, the United States is ceding ground to China. From foreign aid to foreign trade, and from reorganizations to organizational guidance, the Trump administration has embarked on a stunning effort to hobble itself in grappling with what his own secretary of state calls “the most potent and dangerous near-peer adversary this nation has ever confronted.” The problems start at the Department of State. Secretary of State Marco Rubio has asserted that “it’s not normal for the world to simply have a unipolar power” and that the world has returned to multipolarity, with “multi-great powers in different parts of the
President William Lai (賴清德) recently attended an event in Taipei marking the end of World War II in Europe, emphasizing in his speech: “Using force to invade another country is an unjust act and will ultimately fail.” In just a few words, he captured the core values of the postwar international order and reminded us again: History is not just for reflection, but serves as a warning for the present. From a broad historical perspective, his statement carries weight. For centuries, international relations operated under the law of the jungle — where the strong dominated and the weak were constrained. That
On the eve of the 80th anniversary of Victory in Europe (VE) Day, Chinese Nationalist Party (KMT) Chairman Eric Chu (朱立倫) made a statement that provoked unprecedented repudiations among the European diplomats in Taipei. Chu said during a KMT Central Standing Committee meeting that what President William Lai (賴清德) has been doing to the opposition is equivalent to what Adolf Hitler did in Nazi Germany, referencing ongoing investigations into the KMT’s alleged forgery of signatures used in recall petitions against Democratic Progressive Party legislators. In response, the German Institute Taipei posted a statement to express its “deep disappointment and concern”
