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.

The US Senate’s passage of the 2026 National Defense Authorization Act (NDAA), which urges Taiwan’s inclusion in the Rim of the Pacific (RIMPAC) exercise and allocates US$1 billion in military aid, marks yet another milestone in Washington’s growing support for Taipei. On paper, it reflects the steadiness of US commitment, but beneath this show of solidarity lies contradiction. While the US Congress builds a stable, bipartisan architecture of deterrence, US President Donald Trump repeatedly undercuts it through erratic decisions and transactional diplomacy. This dissonance not only weakens the US’ credibility abroad — it also fractures public trust within Taiwan. For decades,
In 1976, the Gang of Four was ousted. The Gang of Four was a leftist political group comprising Chinese Communist Party (CCP) members: Jiang Qing (江青), its leading figure and Mao Zedong’s (毛澤東) last wife; Zhang Chunqiao (張春橋); Yao Wenyuan (姚文元); and Wang Hongwen (王洪文). The four wielded supreme power during the Cultural Revolution (1966-1976), but when Mao died, they were overthrown and charged with crimes against China in what was in essence a political coup of the right against the left. The same type of thing might be happening again as the CCP has expelled nine top generals. Rather than a
Former Chinese Nationalist Party (KMT) lawmaker Cheng Li-wun (鄭麗文) on Saturday won the party’s chairperson election with 65,122 votes, or 50.15 percent of the votes, becoming the second woman in the seat and the first to have switched allegiance from the Democratic Progressive Party (DPP) to the KMT. Cheng, running for the top KMT position for the first time, had been termed a “dark horse,” while the biggest contender was former Taipei mayor Hau Lung-bin (郝龍斌), considered by many to represent the party’s establishment elite. Hau also has substantial experience in government and in the KMT. Cheng joined the Wild Lily Student
Taipei stands as one of the safest capital cities the world. Taiwan has exceptionally low crime rates — lower than many European nations — and is one of Asia’s leading democracies, respected for its rule of law and commitment to human rights. It is among the few Asian countries to have given legal effect to the International Covenant on Civil and Political Rights and the International Covenant of Social Economic and Cultural Rights. Yet Taiwan continues to uphold the death penalty. This year, the government has taken a number of regressive steps: Executions have resumed, proposals for harsher prison sentences
