Motte-and-Bailey of Idealism
I've been following Acharya Prashant and looking into the philosophy of idealism after seeing a few posts and comments here. Before I get to my concerns, let me acknowledge what he does well:
What I Respect:
- He does call out pseudoscience. He has publicly dismissed astrology, homeopathy, and mystical claims on the grounds that they aren't falsifiable or verifiable.
- He advocates for veganism and animal rights. A lot of people have become vegan through his influence. His arguments are grounded in ethics and compassion, and he's helped many make the connection between consumption and violence.
I respect this a lot.
Where I See a Problem:
Despite articulating a rigorous standard for science, his core metaphysical claim fails his own criteria. The claim that consciousness is fundamental and the material world is appearance (maya).
Here's why idealism doesn't hold up as a claim about reality:
It's unfalsifiable. Idealism makes no testable predictions that differ from naturalism. Every possible observation is compatible with "consciousness is fundamental" and also with "the brain generates consciousness." There's no experiment that could distinguish the two. A claim that can't be wrong can't be right either.
But when idealism DOES make testable claims, it fails them. If consciousness is fundamental and the brain doesn't generate it, then:
- Brain damage shouldn't erase specific conscious functions. But it does. Damage to the fusiform gyrus destroys face recognition. Hippocampal damage wipes out the ability to form new memories. Amygdala damage eliminates fear responses.
- Anesthesia shouldn't turn consciousness off. But it does, reliably and reversibly, by targeting specific molecular receptors (GABA, NMDA).
- Progressive neurodegeneration shouldn't gradually erode personality, memory, and awareness in lockstep with tissue loss. But it does.
Proponents of idealism dismiss these as correlations, but they aren't just correlations. These are direct, causal, bidirectional manipulations of conscious experience through the brain.
If consciousness exists independently of the brain, you'd need to explain why damaging this supposed "receiver" systematically destroys specific contents of consciousness. The destruction of particular capacities, rather than just signal strength, fits exactly the predictions of the "brain as generator" model (modern neuroscience).
Idealism handles this by retreating to: "That's just the ego-mind being affected, not the fundamental consciousness." But this is adding ad hoc machinery to protect the claim from evidence. The fundamental consciousness conveniently is poorly defined, can't be measured, detected, or affected by any physical process. It's immune to disconfirmation by definition.
This is the same structure as Last Thursdayism (the universe was created last Thursday with all history planted to appear older) or Young Earth creationism (the Earth is 6,000 years old, fossils were placed to test faith). All three make claims about how reality actually is while being structured so no observation can ever count against them.
I find that the rhetoric fits the motte-and-bailey: When the claim is challenged, retreat to the motte ("Vedanta isn't science, it's philosophy/darshana, you can't attack it with empirical standards"). But when promoting the teaching, imply the bailey (that consciousness being fundamental is actually true, not just a philosophical stance).
The contradiction is: he uses falsifiability to defend against astrology but exempts his own claims from the same standard.
My Question:
Why do people find him compelling?
I am not trying to diss him here, I am actually curious.
Try to go through the rationale and arguments I have attempted to articulate and engage with them if you disagree.
