Back to Popper

Image result for pseudoscience watch

A 2013 anthology, PHILOSOPHY OF PSEUDOSCIENCE, contends that Karl Popper was in essence right on his crucial contentions over falsifiability and science.

Here's a link. 

Specifically, Popper contended first that it is important (as a task within the broad domain of epistemology) for philosophers to distinguish between what is science and what isn't; second that what is science must be in principle falsifiable; third that the falsifiability is linked to the good reasons why sciences are prestigious activities -- the reasons why the word 'science' is worth co-opting.

Those views have gone out of fashion, for a lot of reasons. Susan Haack, for example, argues that the "demarcation problem" is of little significance. Philosophers should stop arguing over what deserves the label "science," in part because she believes falsifiability is also good as a rough guide to valuable thought in a lot of fields of scholarship one wouldn't want to put on the "science" side of such a line.

That is precisely the contemporary suspicion that it is the point of this book to counter. The authors agree that science is not all of knowledge, but it is a very important human project, and its prestige is earned. Thus, demarcating science from non-science, and especially from non-science pretending to be science, is an important endeavor. Further, though Popper was himself open to critique in detail, there is as one of the authors represented here puts it "something profoundly right about the contrasts he sets up...."

England as a Raft?

In a lecture delivered in 1880, William James asked rhetorically, "Would England ... be the drifting raft she is now in European affairs if a Frederic the Great had inherited her throne instead of a Victoria, and if Messrs Bentham, Mill, Cobden, and Bright had all been born in Prussia?"

Beneath that, in a collection of such lectures later published under James' direction, was placed the footnote, "The reader will remember when this was written."

The suggestion of the bit about Bentham, Mill, etc. is that the utilitarians as a school helped render England ineffective as a European power, a drifting raft.

The footnote was added in 1897. So either James is suggesting that the baleful influence of Bentham, Mill etc wore off in the meantime or that he had over-estimated it.

Let's unpack this a bit.  What was happening in the period before 1880 that made England seem a drifting raft in European affairs, to a friendly though foreign observer (to the older brother…

Cancer Breakthrough

Hopeful news in recent days about an old and dear desideratum: a cure for cancer. Or at least for a cancer, and a nasty one at that.

The news comes about because investors in GlaxoSmithKline are greedy for profits, and has already inspired a bit of deregulation to boot. 

The FDA has paved the road for a speedy review of a new BCMA drug for multiple myeloma, essentially cancer of the bone marrow. This means that the US govt has removed some of the hurdles that would otherwise (by decision of the same govt) face a company trying to proceed with these trials expeditiously. 

This has been done because the Phase I clinical trial results have been very promising. The report I've seen indicates that details of these results will be shared with the world on Dec. 11 at the annual meeting of the American Society of Hematology. 

The European Medicines Agency has also given priority treatment to the drug in question. 

GSK's website identifies the drug at issue as "GSK2857916," althou…

Francesco Orsi

I thought briefly that I had found a contemporary philosopher whose views on ethics and meta-ethics checked all four key boxes. An ally all down the line.

The four, as regular readers of this blog may remember, are: cognitivism, intuitionism, consequentialism, pluralism. These represent the views that, respectively: some ethical judgments constitute knowledge; one important source for this knowledge consists of quasi-sensory non-inferential primary recognitions ("intuitions"); the right is logically dependent upon the good; and there exists an irreducible plurality of good.

Francesco Orsi seemed to believe all of these propositions. Here's his website and a link to one relevant paper:

What was better: Orsi is a young man. Born in 1980. A damned child! Has no memories of the age of disco!

So I emailed him asking if I was right that he believed all of those things. His answer: three out of …
