Science and philosophy. A Hackney SITP review

Tonight I made it, somewhat late (sorry), to see Clio Bellenis present on “Is philosophy relevant to science?” at Hackney SITP. This is a subject that has huge resonance for me. For I was once a student of science who became increasingly disenchanted with the subject and who took up philosophy in order to provide some answers to the questions I felt science was unable to answer. And, having started studying physical science at university, I ended up with a degree in philosophy, to the great disappointment of my parents.

So it was with great anticipation that I turned up to the friendly Hackney SITP to see Dr Bellenis speak. Boy, was I disappointed. After (rightly) putting the boot in to Professor Brian Cox for his idiotic attack on philosophy, she gave a very muddled presentation that touched on philosophy of mind and the free will/determinism debate but which managed to avoid any discussion at all about philosophy of science. In the questions that followed, Dr Bellenis presented some astonishingly facile arguments against the existence of God [“He is logically impossible, unless He is a sadist. If God is omniscient, omnipresent and omnipotent, how can there be suffering in the world? He must be evil. Therefore God cannot exist” This argument manages to undervalue the concept of freedom. Every parent knows that it’s better for their child to be free to make mistakes than to be constrained], railed against grammar school tests and, most irritatingly of all, stated that she knew very little about philosophy of science.

Given that this was supposed to be the subject of her presentation, I felt this to be a very major failing. I do prefer it when speakers at this sort of event manage to answer the exam question they have set for themselves.

An alternative approach might have been to identify a few reasonable but controversial propositions that scientists might make and then test them using philosophy. For example:

  1. “Science is the only way to acquire knowledge”. This could have allowed discussion of alternative methods of knowledge-acquisition and whether they are, philosophically speaking, as valid as science. What gives science its higher position, if anything? The work of Paul Feyerabend would be a good reference here. Shouldn’t we be open to mad approaches to knowledge acquisition if they produce information that is useful? Even religious approaches?
  2. “The empirical method is infallible”. This could have allowed discussion of some of the challenges to empiricism. In particular, the work of Thomas Kuhn (which Dr Bellenis sadly misused horribly in the question and answer session: paradigm shifts are fundamental changes in the building blocks of science, not a change from one theory to another. [Incidentally, Kuhn is poison for most skeptics, who do seem to prefer the idea of a linear progression towards perfect knowledge. I do wonder why he’s so popular with them]), which suggests that science can be very bad at analysing evidence fairly, especially when it contradicts the major theories of the day. Conflicting theories often don’t get a fair assessment until there are so many holes in traditional science that it becomes untenable. Doesn’t this mean that scientists should be more receptive to radical, unconventional theories today?
  3. “Only those things that can be replicated using the scientific method shall be considered true”. This could have allowed discussion of logical positivism, which seems to curry favour with some more radical skeptics today, even though the theory has fallen into disrepute in modern philosophy. But what can replace it? What are the implications for science?

Now it’s been some 20 years since I studied philosophy of science, so I’m a bit rusty, I know. But, in my view, this would have provided a much more stimulating framework for discussion of the relationship between science and philosophy than Dr Bellenis’s rather incoherent presentation. Ultimately science doesn’t need philosophy, just as it doesn’t need history or politics. But it’s much, much stronger for taking account of it.

Many thanks to the lovely Alice Sheppard for arranging tonight’s presentation and for making Hackney SITP an essential part of the monthly calendar.
