One of the most remarkable video sequences I have seen

By -
In a documentary called Wild China, I watched two guys use a grasshopper as bait so that they could tie a feather to a live hornet. I kid you not: while the hornet was busy eating the grasshopper, these two guys tied a feather to its waist.

Why would they bother doing that? The feather acted as a tracking device, allowing the two men to follow the horn back to its nest high in a tree. Once there, they smoked all of the adult hornets out of the nest, brought it down to the ground, and proceeded to eat all the grubs inside of it.

But here was what really got me: the hornets seemed to know that the feather was a problem. As soon as the tagged hornet reached the nest, other hornets began chewing through the string that attached the feather to its body, eventually cutting the feather away.

Cruel to be kind means that I love you . Because, while I think you are mistaken, your hearts are in the right place -- yes, even you, Silas --  unlike some people . This Breitbart fellow (discussed in the link above), by all appearances, deliberately doctored a video of Shirley Sherrod to make her remarks appear virulently racist, when they had, in fact, the opposite import.

While that description is not entirely inaccurate, I must say that a lot of these people who today call themselves conservative give me the heebie-jeebies.

"Pre-Galilean" Foolishness

 I am currently reading The Master and His Emissary , which appears to be an excellent book. ("Appears" because I don't know the neuroscience literature well enough to say for sure, yet.) But then on page 186 I find: "Asking cognition, however, to give a perspective on the relationship between cognition and affect is like asking astronomer in the pre-Galilean geocentric world, whether, in his opinion, the sun moves round the earth of the earth around the sun. To ask a question alone would be enough to label one as mad." OK, this is garbage. First of all, it should be pre-Copernican, not pre-Galilean. But much worse is that people have seriously been considering heliocentrism for many centuries before Copernicus. Aristarchus had proposed a heliocentric model in the 4th-century BC. It had generally been considered wrong, but not "mad." (And wrong for scientific reasons: Why, for instance, did we not observe stellar parallax?) And when Copernicus propose
