Epiphenominalism commits the stolen concept fallacy. It utilises the very concept it is denying the root causal function of, in this case, the concept of consciousness as an active, causally efficacious awareness.
In the very act of affirming the doctrine, consciousness is required to play a causal role (thinking, choosing words, communicating).
Example
“Consciousness exists, but it doesn’t cause anything.”
Info
The concept of causal-consciousness is being stolen to strip consciousness of its causal identity. How did the one uttering such a statement do so if their consciousness is incapable of playing a causal role?
