The Fraud of Agriculture

Scholars once proclaimed that the agricultural revolution was a great leap forward for humanity. They told a tale of progress fuelled by human brain power.Evolution gradually produced ever more intelligent people. Eventually, people were so smart that they were able to decipher nature’s secrets, enabling them to tame sheep and cultivate wheat. As soon as this happened, they cheerfully abandoned the gruelling, dangerous, and often spartan life of hunter-gatherers, settling down to enjoy the pl...

 Theoretical Uncertainty has No Meaning

If one looks at the history of knowledge, it is plain that at the beginning men tried to know because they had to do so in order to live. In the absence of that organic guidance given by their structure to other animals, man had to find out what he was about, and he could find out only by studying the environment which constituted the means, obstacles and results of his behavior. The desire for intellectual or cognitive understanding had no meaning except as a means of obtaining greater secur...

 Exercises for Emotional Maturity in Children

Let's focus on the skill of expanding sensitivity. Increased attention to music, nature, and animals can increase sensitivity. Once you identify these outlets, set up a series of exercises that use these focal points to draw out sensitivity. For example: Listening: Listen to a piece of beautiful music for 10 minutes. Close your eyes and let the notes guide your mind. Focusing: Choose an animal (even an ant) and follow it for 10 minutes; watch it with full attention. Relaxing: Sit quietly for...

 The Dilemma of Human Diversity Across the Cosmos

When life spreads out and diversifies in the universe, adapting itself to a spectrum of environments far wider than any one planet can encompass, the human species will one day find itself faced with the most momentous choice that we have had to make since the days when our ancestors came down from the trees in Africa and left their cousins the chimpanzees behind. We will have to choose, either to remain one species united by a common bodily shape as well as by a common history, or to let our...

 Animal Plants: Life Adapted to a Vacuum

"These remarkable creatures combine the characteristics of animals and plants and so I call them animal-plants. ..." "All right. Don't get angry. Just explain how your creatures avoid getting dried up like mummies." "That is simple. Their skin is covered with a glassy layer, thin and flexible but absolutely impermeable to gases and liquids and all kinds of particles, so that the creatures are protected from any loss of material. . . . Their bodies have appendages which look like wings and a...

 Newton's Perspective on the Universe

As all regions below are replenished with living creatures, (not only the Earth with Beasts, and Sea with Fishes and the air with Fowls and Insects, but also standing waters, vineger, the bodies and blood of Animals and other juices {49} with innumerable living creatures too small to be seen without the help of magnifying glasses) so may the heavens above be replenished with beings whose nature we do not understand. He that shall well consider the strange and wonderful nature of life and th...

 Human Respiration is Not a Source of Carbon Emissions

That's not a problem. The CO2 that's released by humans (and animals) is produced by metabolising carbon from food, and the food comes from plants that have been grown recently. During their growth, the plants have absorbed an equivalent amount of CO2 from the atmosphere. Even when eating meat, the animals are typically only a few years old and were fed on recently grown plants. In contrast, the cars run on fossil fuels that are hundreds of million years old.

 Human Respiration is Carbon Neutral

The very first time you learned about carbon dioxide was probably in grade school: We breathe in oxygen and breathe out carbon dioxide. Any eight-year-old can rattle off this fact. More specifically, the mitochondria within our cells perform cellular respiration: they burn carbohydrates (in the example shown below, glucose) in the oxygen that we breathe in to yield carbon dioxide and water, which we exhale as waste products, as well as energy, which is required to maintain...

 Everything is Made of Atoms

Everything is made of atoms. That is the key hypothesis. The most important hypothesis in all of biology, for example, is that everything that animals do, atoms do. In other words, there is nothing that living things do that cannot be understood from the point of view that they are made of atoms acting according to the laws of physics. This was not known from the beginning it took some experimenting and theorizing to suggest this hypothesis, but now it is accepted, and it is the most useful t...
