Neuropsychologist Nicholas Humphrey vs. Philosopher Daniel Dennett


Word Count: 670

It can be argued that the exact antithesis of Daniel Dennett's position (on consciousness) is put forward by the neuropsychologist Nicholas Humphrey. This is graphically shown in Humphrey's phrase “the experience of raw being”. That is, a level of consciousness that's worlds away from Dennett's propositional or functional consciousness. In addition, it's a “lower-level” of consciousness that's “unreflected on”. In more detail:

“[P]rimitive sensations of light, cold, smell, taste, touch, pain; a the is-ness, the present tense of sensory experience, which doesn't require any further analysis or introspective awareness to be there for us but is just as ? Of existence.”

If such a state, what would Dennett have to hold onto? Where's the third-person heterophenomenology in all of this? Where are the judgments or the “verbal reports”?

It doesn't help that Humphrey uses terms like “the is-ness” and the like. The problem, then, is that Humphrey's account may be seen like a position on some kind of "spiritual" or Zen-like states. However, I believe that Humphrey hasn't all this in mind at all. These aren't Zen-like or spiritual states of consciousness he's referring to. They're states that most of us experience at certain points each and every day. And neither are these “raw” states the end result of mental preparations and will power; as spiritual states often are. I would argue that they are the givens of everyday experience or consciousness.

In any case, Dennett would surely reject these conscious states. He'd be an eliminativist and a verificationist about them. They are, after all, private (if in a very rudimentary sense). Still, these raw states don't necessarily fall foul of the strictures of behaviourists, Wittgenstein, Quine, functionalists and the rest. That's because nothing much is being claimed for them. They aren't the “source of meaning” (which Wittgenstein and Quine rejected). They don't constitute a "private language" of any kind. And neither do they constitute first-person “infallible knowledge”. They're simply basic experiences. Therefore, almost by definition, they're outside of science and Dennett's own philosophical heterophenomenology and verificationism.

Basically, one can admit that they serve no purpose... as such. Nonetheless, they do serve a purpose for Humphrey himself in that they show him

that is what's it's like to be me, or what it's like to be a dog, or what it's like to be a baby”.

So we don't need to build a philosophical edifice on top of Humphrey's “raw being” or “is-ness”; as Descartes, the phenomenologists and others did. We simply need to accept that these states are part of consciousness. And they're essentially above and beyond all that's functional, cognitive, judgmental, propositional and the like.

Earlier the lack of purpose for these basic conscious states was mentioned. And that's why Dennett said that following to Humphrey:

Look, I hear what you're saying, but I simply don't have any reference point for it. Your raw sensations, if they exist, leave nothing behind. They might as well never have occurred.”

So as was said earlier:

i) If the conscious states Humphrey refers to have no “reference point”, then they serve no purpose.
ii) If they “leave nothing behind”, then they serve no purpose.
iii) And if they “might as well never have occurred”, then they serve no purpose.

In other words, to Dennett, all this basically means (surely) that even if these consciousness states serve no purpose, then they don't/mustn't exist. That really does seem to be Dennett's position. And it is pure verificationism and indeed eliminativism at one and the same time.

This conclusion, therefore, is completely at one with Humphrey when he responds to Dennett by saying that

[f]or Dan, the basic constituents of consciousness are ideas, judgements, propositions, and so on”.


For Dan, if there's nothing left after the sensation has passed – nothing in the way of a text, which says something like, 'Memo to self: have just had a sensation' – then it didn't happen.”

Dennett's position is extreme. (At least it is to me.) What's more, I can't help believing that it's obviously false.
