Nice long piece on Thomas Kuhn…

Of course he was the author of The Structure of Scientific Revolutions. Mathew Rees’ perspective on how the concept of paradigm shift has fared is here, in The New Atlantis.

My own view is that neuroscience is in need of a paradigm, never mind the shift. We’re still largely data collectors as far as the big questions of how mind arises from brain activity.

On Thomas Kuhn and Paradigm breaking…

From this weekend’s Guardian, here.

Money quote:

But what really set the cat among the philosophical pigeons was one implication of Kuhn’s account of the process of paradigm change. He argued that competing paradigms are “incommensurable”: that is to say, there exists no objective way of assessing their relative merits. There’s no way, for example, that one could make a checklist comparing the merits of Newtonian mechanics (which applies to snooker balls and planets but not to anything that goes on inside the atom) and quantum mechanics (which deals with what happens at the sub-atomic level). But if rival paradigms are really incommensurable, then doesn’t that imply that scientific revolutions must be based – at least in part – on irrational grounds? In which case, are not the paradigm shifts that we celebrate as great intellectual breakthroughs merely the result of outbreaks of mob psychology?

An institute for advanced study: what purpose?

In the short time before the Spring semester commences, it’s perhaps worthwhile to step back and consider  the question of: why an institute for advanced study?

There are quite a few such institutes these days, and not just here in the States, but the granddaddy of them all is the one at Princeton, where Albert Einstein spent the War years in the 1940’s. That Institute has as its key mission “to encourage and support fundamental research in the sciences and humanities – the original, often speculative, thinking that produces advances in knowledge that change the way we understand the world.”

Note the idea of producing advances that “change the way we understand the world”.  That idea of course echos Thomas Kuhn’s notion of a paradigm shift. Not all research does this; most findings are incremental in nature. To aim for paradigm shifts is bold and fraught with risk.

Which brings to mind this commentary on venture capitalists, which appeared on my twitter feed today. Here the operative meme is that VC’s are too cautious these days. That like the Howard Hughes Medical Institute, they should take bigger risks:

VC firms must behave more like the Howard Hughes Medical Institute, which funds radical scientific innovations over long periods of time – and less like the National Institutes of Health, which prefers incremental, almost-sure advances.

 I would argue that it is in institutes for advanced studies that such science takes place, often with great collective purpose and across seemingly vastly different domains of knowledge. It is certainly what we are about at the Krasnow Institute for Advanced Study.

I’ll close with this quote, lifted from our web site, that captures Krasnow nicely:

In the end, we believe that there is no substitute for recruiting the very best people and turning them loose to explore the fascinating world of thought somehow emergent from our biological nature and evolution as Homo sapiens.
