The Depth of Empiricism

[This is part of a set: Thinking]

In the previous post on empiricism I looked at how philosopher Stephen Law missed a few tricks when he debated chemist Peter Atkins.

In this post I pick up on Jerry Coyne’s post making similar points: Can philosophy or religion alone establish facts?

I think the problem for philosophers is two-fold.

One is their commitment to their profession.

I see this as similar to the position of some priests who in many respects seem to accept all the intellectual criticisms of religion and faith, but can’t quite bring themselves to go the whole hog – there’s too much to give up, too much cognitive dissonance to contend with. So they fall back on faith – the only excuse left to maintain belief.

In the case of philosophers it seems to be their indebtedness to the history of the subject. This too is similar to theology – where the ideas of the ancients seem to retain some philosophical sacredness. Philosophers seem to need their ancients more than any other discipline with the exception of history. That “there’s nothing new in history” might well be applied to how some philosophers see their field.

And this brings me to the other problem. It doesn’t matter how much philosophy they claim to do, how much critical thinking they perform, how much evidence they consider, they still seem to retain a conviction to the primacy of thought and reason. It doesn’t matter how much pure reason is criticised, they still indulge in it.

I wonder if this stems from Descartes Cogito. This is a pretty good starting point, and one I use myself, in particular here. But many philosophers, even non-dualists, seem to be stuck with the idea that because we start out by discovering that we think, that this is our natural and primary mode of understanding. I don’t think they get how deep empiricism goes, how much we are empirical creatures before thinking entities.

Okay, so that’s where we start, with thinking about stuff. But before long, when we follow the trail and side-step Solipsism, we are left with a few clues to the fact that we are not primarily thinking entities.

Evolution is the big clue. You have to throw out evolution to avoid inferring the following from it.

We are evolved from creatures that didn’t have brains. Our ancestors were various in nature, ranging from the simple single cellular, through multiple cellular, to entities with multiple organs. Back then we were primarily experiential sensory creatures – and by sensory I mean in the simplest sense: physical and chemical interactions at our surfaces. And where there were neuronal nervous systems they might not be central nervous systems but distributed neural nets. An advantage of electrical communication over purely physical and chemical is the speed and the targeted nature of the connections. As early as neurons might have evolved they weren’t forming what we would call brains – though, given a physicalist perspective, that begs the question of what a brain is anyway. Nevertheless, through physical contact, chemical interaction, neuron transmission, our ancestors were empirical creatures.

This is what we still are, of course. I guess our sensing using light and sound removes us as whole entities from direct contact with much of our environment. Our actual contact with the wider environment, through touch, is often more difficult, and often undesirable: there are many things for which it’s safe to look at but not to touch; and if you can touch you may well be too close. Vision and hearing give us some protection against dangers, but they also isolate us from our environment to some extent.

This gives us the illusion that we stand alone in the world, so that we acquire (once we have thinking brains) the feeling that we are subjective individuals independent of the rest of the world.

We seem to be enclosed minds, when really we are empirical creatures that have brains connected to the outside world by remote sensing.

On top of that, this brain that we each have awakens and becomes aware of itself. This happens to each of us as individuals as we develop from an infant into a fully interactive child, teen, adult. And collectively it has come about culturally, historically, as our collective recorded awareness of our consciousness has dawned on us as a species (and maybe our ancestor species had some of this awareness too).

The dawn of recorded history and the emergent self-awareness of the infant are mutual metaphors, both beginning, or at least becoming sufficiently complex, with the acquisition of written language for the species and language generally for the infant.

The problem has been that our philosophical view has been dominated by this awakening of the mind, as if it is the primary source of knowledge, when in fact it’s our experiential empirical nature that has primacy. Our mind is merely looking at, analysing, speculating, on what we experience – and mostly with very poor access to most of our experiences.

Not only are we not directly aware of most of what our bodies or even our brains are experiencing, but we don’t have access directly to our deep past experiences – those that we have accumulated in our DNA.

I think most people accept now that we are the combination of nature and nurture – to the extent that this dichotomy is considered a very simplistic notion. We are each of us a developing complex system of our inherited biology responding to its environment, and in turn altering that environment through the decision processes that go on in our biological brains, which in turn effects how our biology responds further. We might be inclined, biologically, to be a couch potato or an athlete, but we can generally still become either, and even both – who hasn’t seen a once keen athlete turn to flab after they retire.

Though not specifically part of evolution, abiogenesis seems the only real source of what we call life. And, though there is no direct evidence to support abiogenesis, there is no good alternative hypothesis on the table. It seems that we come from inanimate matter, and we are inanimate matter – just inanimate matter that has become pretty dynamic.

So, there is nothing to suggest there is anything else going on in our heads. There is no evidence for any other source of thinking than it being matter in action. We are ultimately empirical beings, even in our reasoning in our heads. The processes going on in there are real material experiences in their own right; but it is we who categories experiences into externally sensed, or internally reasoned, as if the reason was pure and unsullied by real nasty experience.

In this respect there isn’t a significant difference between the peripheral neurons and the neurons in our brains. Neurons are communication mechanisms, whether in our arms or in our heads. While peripheral neurons connect other tissue to the brain, brain neuron connections are mostly with other brain neurons. So in a very real sense the brain neurons are sensing each other: they are empirical. We are empirical first and foremost. Thinking is an evolutionary add-on.

That some philosophers don’t get how deep empiricism goes is exemplified by the philosopher Steven Law in his discussion with Peter Atkins.

So, some philosophers seem to think that reasoning, while our primary tool of analysis, is actually our primary tool of discovery. They are mistaken. Unless one rejects evolution we can only conclude that we are experiential, empirical beings who acquired reasoning late in the day. It may be true that our reasoning provides us with far more than our sensory bumbling through life alone ever could. But it’s an even greater mistake to think that reasoning alone could do anything – especially since without sensory experience there would be no stimulus for neurons to evolve with which we could do any thinking. Some philosophers have it arse about face.


Update…

Jerry Coyne reviews a portrait of E O Wilson.

This bit strikes me as a good assessment of philosophy:

Generation after generation of students have suffered trying to “puzzle out” what great thinkers like Socrates, Plato, and Descartes had to say on the great questions of man’s nature, Wilson said, but this was of little use, because philosophy has been based on “failed models of the brain”.
