Philosophy and the Chain of Custody

Yesterday in this space I quoted a fragment conventionally attributed to the pre-Socratic philosopher Heraclitus and, in essence, free associated from that.

That doesn't advance the cause of scholarship one tiny bit but, heck, it's a hobby blog.

Somewhat more interesting than my personal train of association chugging along its tracks might be the question: how did fragments like that get from Heraclitus to us?

Fortunately, the tradition whereby philosophers write the history of the issues with which they deal goes back a long way. Setting Plato aside (because of the dramatic/literary demands of the dialog form), Aristotle started the practice of setting one's own table historically.

A less well known later fellow named Sextus Empiricus seems to have played a big role. SE lived in the second or third century of the Christian era. He was a skeptic, that is, he believed that no firm beliefs are rational, and that by accepting our ignorance we can achieve tranquility.

Yes, one feels compelled to interject that the skeptic here implies a firm belief system of his own: that tranquility is a valuable condition, and that the acceptance of ignorance gets us there, are both beliefs he chooses not to suspend. Still, I'm uninterested in arguing with him now.

Guided by that goal, Sextus aided the world's tranquility by writing a book the title of which is generally and confusingly translated "Against the Mathematicians." "Against the Theorizers" might be a better rendering. The point was to catalog various claims to knowledge that had been made throughout the ages, and to show how each had failed.

In cataloging them, he preserved them. Much of what is called a "fragment" of philosopher X is just a piece that SE saw fit to quote, because X made it into his list of "mathematicians."

One of the components of "Against the Mathematicians" is "Against the Physicists," which is where we find discussion of pre-Socratic  dogmas about the physical cosmos. Here's a link to a book with further information about this process of "doxographic transmission" through skepticism.  https://books.google.com/books?id=9kzzCQAAQBAJ&pg=PA30&lpg=PA30&dq=Sextus+Empiricus+importance+as+a+source&source=bl&ots=QmgxsC6G_A&sig=2dHr6bXH3-C9T-TQ2nv9j71Dm88&hl=en&sa=X&ved=0ahUKEwiDrvPJurPVAhWIeD4KHQc6DOUQ6AEIUTAJ#v=onepage&q=Sextus%20Empiricus%20importance%20as%20a%20source&f=false

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 …
