Uncommon Descent Serving The Intelligent Design Community

At Mind Matters News: What if extraterrestrials can’t afford to take chances with us?

The Dark Forest Hypothesis assumes that we can use sociology to figure out what extraterrestrial intelligences might be like or might want. But can we? What's become of sociology these days? Read More ›

[L&FP 39:] Implication logic is pivotal to understanding how we think as duty-bound rational creatures

In recent months we have had several forum threads, which naturally tend to throw up onward topics worth headlining. Here, I will headline some observations on implication logic in deductive and in inductive reasoning. However, first, the core of the logic of implication. Algebraically, p => q is analysed as ~[p AND ~q]. Interpreted, for whatever reason, p being so is sufficient for q to also be so. This compound proposition does NOT assert that p, only that p is sufficient for q. Similarly, q is NECESSARY for p, i.e. if q can be false and p true, q is not implied by p. As a bare structure, this is termed material implication, fleshing out the why of the implication Read More ›

New form of human DNA found – a four-stranded knot

Researchers: The new shape looks entirely different to the double-stranded DNA double helix... "We think the coming and going of the i-motifs is a clue to what they do. It seems likely that they are there to help switch genes on or off, and to affect whether a gene is actively read or not." Just a random swish of chemicals, right? Read More ›

Michael Egnor reflects on Joshua Swamidass’s proposal for effectively canceling Christian colleges

Egnor: "Notably, Swamidass completely leaves out the one criterion that is the cornerstone of accreditation of educational institutions: outcome metrics... don’t know (and Swamidass has nothing to say about it) how students from Christian colleges compare, but is it well established that homeschooled kids (who are disproportionately taught by conservative Christian families) score almost 100 points higher on the SAT and score correspondingly higher on the ACT than the national average." Okay, but no one sponsoring the war on math is concerned about outcomes because educators have the power to jimmy marks to reward whatever they want to reward and then pass the problem on to others who must then do the same.

Remember space junk ‘Oumuamua? A conventional explanation is now offered: Nitrogen ice from Pluto

It’s curious how folklore can prevail for ages in science as long as it has a naturalistic origin. Maybe Top People shouldn’t count on everyone just forgetting that now. Read More ›

Gregory Chaitin’s take on: Was math invented or discovered?

Chaitin, best known for Chaitin's unknowable number: "Some mathematics, I think, is definitely invented, not discovered. That tends to be trivial mathematics ... But other mathematics does seem to be discovered. That’s when you find some really deep, fundamental mathematical idea, and there it really looks inevitable. " Read More ›

A Summary of the Evidence for Intelligent Design—study guide

At the suggestion of a pastor friend, I have developed a study guide to go along with the video “A Summary of the Evidence for Intelligent Design,” which was highlighted in an article by Brian Miller at Evolution News. The study guide is here. Although there is only one section (4b) that relates ID to the Bible, I think it could serve as a nice introduction to ID for a church discussion group. Notice the video now has Spanish and Polish subtitles.

Researchers: Human immune system does not “recognize” deep sea microbes

They might be useful, as the researchers say. But now that they are starting to work with them, we’d better hope that none of them turn on us, for lack of something more familiar to them that they can infect. Read More ›
