Success as Proof of Virtue

Ivanka contrasts “proactive” people, who are “passionate and productive,” with “negative people,” those who are “swayed by the external and are frequently the victim of circumstance.” Her worldview, it turns out, is not so different from her father’s. Both see society through the lens of quasi-mystical corporate self-help, the sort pioneered by Norman Vincent Peale, author of The Power of Positive Thinking and a major influence on Donald Trump. In their schema, success is pr...

 How Science Resists the Philosophical Concept that Percep...

In the traditional theory, which still is the prevailing one, there were alleged to exist inherent defects in perception and observation as means of knowledge, in reference to the subjectmatter they furnish. This material, in the older notion, is inherently so particular, so contingent and variable, that by no possible means can it contribute to knowledge; it can result only in opinion, mere belief. But in modern science, there are only practical defects in the senses, certain limitations of ...

 The Problem of Inferring Anything about the Star Trek Uni...

The second problem has more to do with using Starfleet as the lens through which we draw conclusions about Federation society. If I were to show some alien society a documentary about the United States, set primarily on a US aircraft carrier, with ~90% of the situations and characters taking place in a military context, my alien viewers would draw some very interesting inferences about the US (or, more broadly, all of human society). They'd think we were a rigidly hierarchical society. They'd...

 Couples as Socially-Distributed Cognitive Systems

In everyday life remembering occurs within social contexts, and theories from a number of disciplines predict cognitive and social benefits of shared remembering. Recent debates have revolved around the possibility that cognition can be distributed across individuals and material resources, as well as across groups of individuals. We review evidence from a maturing program of empirical research in which we adopted the lens of distributed cognition to gain new insights into the ways that remem...

 Summary of Postmodernism

The teaching that there is no objective reality, but rather many subjec¬ tive realities, or in this case, that the subjective realities are on an equal par with the objective reality (you're dead!) in turn influences students' views of the primacy of knowledge. To critics, history is no longer the search for what really happened, but rather the victor's interpretation as seen through the lens of power and oppression, and it bears a cultural and political focus. Literature is no longer a stud...

 Newton's Experiment Proving White Contains All Colors

Newton wasn't the first person to make a rainbow with a prism. Other people had already got the same result. But many of them thought the prism somehow 'coloured' the white light, like adding a dye. Newton's idea was quite different. He thought that white light was a mixture of all the colours, and the prism was just separating them from each other. He was right, and he proved it with a pair of neat experiments. First, he took his prism, as before, and stuck a narrow slit in the way of the co...

 Evolution of the Eye

A possible sequence of such changes begins with simple eyespots made of light-sensitive pigment, as seen in flatworms. The skin then folds in, forming a cup that protects the eyespot and allows it to better localize the light source. Limpets have eyes like this. In the chambered nautilus, we see a further narrowing of the cup’s opening to produce an improved image, and in ragworms the cup is capped by a protective transparent cover to protect the opening. In abalones, part of the fluid in t...
