Extra Dimensions, Materialism and Consciousness: Science vs. Woo

A week or so ago, I participated in a super saturated Deepak Chopra-esque woo discussion on Facebook. It astounds me that a participating member of a technologically advanced society can confidentially assert the statements I’ve captured below. I don’t know how we can dispel so many of these misconceptions but I do know that they are widespread and often held by intelligent people. I can only try to wash away some of the ignorance one Facebook discussion at a time.


For the rest of this article, I will sum up the poster’s arguments and discuss each.

Point One: Other dimensions exist and they make up the spiritual world.

This person sees the extra dimensions (in addition to the three we are familiar with: two spatial and one temporal) that many theories in physics postulate in an attempt to unify the four fundamental forces (gravitational, electromagnetic, strong nuclear and weak nuclear) as haunted by spirits. While there are promising mathematical models that suggest the existence of extra dimensions, scientists have so far not found evidence to confirm these models (though they’re working on it). If this poster could prove the existence of extra dimensions, he’d win a nobel prize and if he could prove that those dimensions were populated by spirits, he’d force the rewriting of scientific laws. (the Second Law of Thermodynamics comes to mind).

Point Two: Materialism is false.

If you believe that spirits exist and you are philosophically consistent, you reject materialism because materialism denies the existence of such things. I’ve spoken about how humans are not ghosts in the machine because there is no supporting evidence that stands up to scientific scrutiny. Science tells us, we are our brains or as neuroscientist Christof Koch likes to put it, “no brain, never mind!”. The brain endows us with consciousness, gives us our personality, our predispositions, our cognitive abilities, our level of empathy and so on. When our brains die, the electrical impulses and matter than generates them dies too and we exist no more.

The poster also asserts that science limits its queries to the so-called “five senses”; this is patently false. For example, science has led to the development of technology that uses electro-magnetic radiation, most of it imperceptible to human senses. We cannot see, hear, smell, taste or feel many radio waves, yet thanks to the science that discovered them, we use them to communicate, learn new things about the cosmosdiagnose medical conditionscook our meals and much more.

Point Three: The Hard Problem of Consciousness is unsolvable.

The Hard Problem of Consciousness is no more unsolvable than the problem of how sicknesses are spread (The Germ Theory of Disease) or how traits are passed from one generation to the next (heredity by DNA). Imagine that our ancestors had taken this writer’s advice to “stay agnostic”, instead of striving to truly understand the nature of things? Where would our civilization be today if those before us had accepted claims that bad air and evil spirits make us sick or that god created humans and all living things in their current forms?

Lastly, when the poster calls the scientific quest to understand consciousness a “dogma that has limited evidence”, he shows that he fundamentally misunderstands science. Dogma, according to the Merriam-Webster dictionary, is a belief or set of beliefs that is accepted by the members of a group without being questioned or doubted. In contrast, science sees nothing as sacred; as Richard Feynman famously said,

It does not make any difference how beautiful your guess is. It does not make any difference how smart you are, who made the guess, or what his name is – if it disagrees with experiment it is wrong. That is all there is to it.

Because science has not yet solved the The Hard Problem it does not mean that we get to stuff those gaps in our knowledge with spirits or any other fantastical beings and as Christof Koch knows, a theory for “how and why the physical world is capable of generating phenomenal experience…can’t just be vague, airy-fairy, but must be concrete, quantifiable, and testable“- (Koch p. 115) and such theories do exist.

I think this poster believes he is open-minded while those that see science as the best way to ascertain truth, are close-minded because we do not accept mere assertions as truth (the plural of anecdote is not data). This is where it is important to remember to keep an open mind but not so open that your brains fall out.

CBC News discusses atheism, badly as usual

Whenever CBC tackles atheism on its news network, they bungle it hideously. Several times they’ve had panels discussing atheism without a single atheist present, and no one speaking for an atheist position – you can imagine how they’ve turned out. Well on The National on Sunday night, Wendy Mesley – … Continue reading
