Anthropocene Traps

The concept of evolutionary traps has been used almost exclusively for studying how non-human species respond to cues in anthropogenic environments [24–34]. Key examples include artificial human lights attracting insects, island species responding naively to the presence of introduced predators, and seabirds not being able to discriminate between the cues of marine plankton and marine plastics [34–36] (figure 1a). In the context of humans, evolutionary mismatch is a much more frequently u...

 Understanding Cause and Effect is Based on Experience

Were a man, such as Adam, created in the full vigor of understanding, without experience, he would never be able to infer motion in the second ball from the motion and impulse of the first. It is not anything that reason sees in the cause, which make us infer the effect. Such an inference, were it possible, would amount to a demonstration, as being founded merely on the comparison of ideas. But no inference from cause to effect amounts to a demonstration, as being founded merely on the compar...

 Scientific Laws Mean That God has No Freedom

he one remaining area that reHgion can now lay claim to is the origin of the universe, but even here science is making progress and should soon provide a definitive answer to how the universe began. I published a book that asked if God created the universe, and that caused something of a stir. People got upset that a scientist should have anything to say on the matter of religion. I have no desire to tell anyone what to believe, but for me asking if God exists is a valid question for science...

 The Universality of Play

Gutsmuths.—Many of the ideas in PHome are better expressed, though independently arrived at, in the remarkable volume on play, published by Gutsmuths, ‘the father of play in Germany,’ towards the end of the eighteenth century. Gutsmuths recognised the universality of play among all ages and all peoples, the infinite number of games and the skill exhibited by the race in their invention and manipulation, the health-giving quality of play and its ultimate origin (though fatigue and ennui served...

 Our Modern Worldview and Morality is Shaped by Science

To begin with, the findings of science imply that the belief systems of all the world’s traditional religions and cultures—their theories of the genesis of the world, life, humans, and societies—are factually mistaken. We know, but our ancestors did not, that humans belong to a single species of African primate that developed agriculture, government, and writing late in its history. We know that our species is a tiny twig of a genealogical tree that embraces all living things and that emerged...

 The Great Lifespan Escape

At the time when the lines begin, in the mid-18th century, life expectancy in Europe and the Americas was around 35, where it had been parked for the 225 previous years for which we have data.3 Life expectancy for the world as a whole was 29. These numbers are in the range of expected life spans for most of human history. The life expectancy of hunter-gatherers is around 32.5, and it probably decreased among the peoples who first took up farming because of their starchy diet and the diseases ...

 A Student's Skill-Level Should be Private

A student's skill level should be a private matter, between him and the teacher, and students who are behind should be able to work comfortably, without embarrassment. "They know they should know more. They know they should not be working on tens and ones when their friends are doing division and fractions and all that, and there's no shame in working on it with the computer." Actually, the same principle applies to kids who are off-the-charts advanced: if they just want to relax and do high-...

 Star Wars Nostalgia VS Star Trek Futurism

Also, Star Wars is set in a fantasy past that can look like anything, while Trek is supposed to be a projection of what we imagine our own future to look like. And Star Wars has always been an exercise in nostalgia from the start — nostalgia for ’30s movie serials and comic strips, for ’40s war movies, for ’50s hot rods and samurai movies, etc. It’s always, always been based on the past and set in the past. Star Trek looks to the future, and our idea of the future is always changing.

 The Volumetric Approach to History

You will be thinking that we are coming to the end of this book: we’ve dealt with eight centuries, so there are only two to go. You may be surprised to learn, therefore, that in historical terms we are not even halfway. The reason for this discrepancy is that history is not time, and time is not history. History is not the study of the past per se; it is about people in the past. Time, separated from humanity, is purely a matter for scientists and star-gazers. If a previously unknown uninhabi...

 Of All Times in which to Live, You Would Choose Today

I don't think in terms of one year, but I can tell people what I genuinely believe, which is that if we take responsibility in being involved in our own fate if we participate, if we engage, if we speak out, if we work in our communities, if we volunteer, if we see the joy that comes from service to others, then all the problems that we face are solvable despite all the terrible news that you see, despite all the genuine cruelty, pain, and hardship people are experiencing all around the world...
