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.

Congressman Mike Gallagher (R-WI) and Congressman Raja Krishnamoorthi (D-IL) led a bipartisan delegation to Taiwan in late February. During their various meetings with Taiwan’s leaders, this delegation never missed an opportunity to emphasize the strength of their cross-party consensus on issues relating to Taiwan and China. Gallagher and Krishnamoorthi are leaders of the House Select Committee on the Chinese Communist Party. Their instruction upon taking the reins of the committee was to preserve China issues as a last bastion of bipartisanship in an otherwise deeply divided Washington. They have largely upheld their pledge. But in doing so, they have performed the
It is well known that Chinese President Xi Jinping’s (習近平) ambition is to rejuvenate the Chinese nation by unification of Taiwan, either peacefully or by force. The peaceful option has virtually gone out of the window with the last presidential elections in Taiwan. Taiwanese, especially the youth, are resolved not to be part of China. With time, this resolve has grown politically stronger. It leaves China with reunification by force as the default option. Everyone tells me how and when mighty China would invade and overpower tiny Taiwan. However, I have rarely been told that Taiwan could be defended to
It should have been Maestro’s night. It is hard to envision a film more Oscar-friendly than Bradley Cooper’s exploration of the life and loves of famed conductor and composer Leonard Bernstein. It was a prestige biopic, a longtime route to acting trophies and more (see Darkest Hour, Lincoln, and Milk). The film was a music biopic, a subgenre with an even richer history of award-winning films such as Ray, Walk the Line and Bohemian Rhapsody. What is more, it was the passion project of cowriter, producer, director and actor Bradley Cooper. That is the kind of multitasking -for-his-art overachievement that Oscar
Chinese villages are being built in the disputed zone between Bhutan and China. Last month, Chinese settlers, holding photographs of Chinese President Xi Jinping (習近平), moved into their new homes on land that was not Xi’s to give. These residents are part of the Chinese government’s resettlement program, relocating Tibetan families into the territory China claims. China shares land borders with 15 countries and sea borders with eight, and is involved in many disputes. Land disputes include the ones with Bhutan (Doklam plateau), India (Arunachal Pradesh, Aksai Chin) and Nepal (near Dolakha and Solukhumbu districts). Maritime disputes in the South China
