Why is the Hard Problem of Consciousness so Hard? Intentionality.

Someone I know sent me some material related to their research on consciousness, asking for some feedback. What follows is an edited version of what I wrote to them.
Flint Spear and Arrow-Heads
Solving the easy problem of consciousness — by explaining the causes and neural correlates of particular conscious experiences — is challenging but at least conceivable. This is not so for any claim to have solved the hard problem of consciousness — it is going to evoke skepticism from both scientists and philosophers. I’m one of the many neuroscientists that do not think the hard problem is solvable — to us it is not clear that phenomenal consciousness is a scientifically tractable phenomenon in the first place.

Science does not disprove free will

Someone contacted me through Quora recently because they were having an existential crisis — it was stimulated by the ostensibly scientific notion that humans do not have free well.

Any theory that insists that we do not actually make choices is going to causes distress among many people who valorize academic thinking. Many hard-nosed metaphysicians simply don’t care about the mental well-being of the general public. I find this attitude simultaneously patronizing and irresponsible.

Yanny or Laurel? A perspective from the science of mind and brain

I really like the Yanny versus Laurel meme, which exploded yesterday. It helps illustrate some key points about human perception:

  1. In some situations people can differ wildly in their experience of low-level perception.
  2. Active top-down expectations (and other, weirder processes) have a strong effect on low-level perception.

So basically, it’s an auditory version of #ThatDress.

Is a memory a bunch of atoms? And does this mean we can transfer exact memories?

I was asked the following question on Quora.

Are specific memories just arrangements of atoms in our brains? Could you put certain molecules in someones head and give them an exact memory that you had?

Short answer: No.


Modern science has shown that every thing is an arrangement of atoms: neurons, apples, tables, rockets, asteroids, aardvarks… they are all made up of atoms.

The question now is this: is a memory a thing?
